Looking at Window Film Data

Have you ever been asked to look at data you aren’t familiar with, and to decipher it yourself? If not, you probably will soon if you’re shopping for window film. We in the Window Film Industry have a tendency to hand over product cards with tons of data, but not much insight on what it all means.

When shopping for window film, you’ll be handed a window film card, generally with an enclosed sample, and all the pertinent info about that product on it. But what does it mean to you, and what data or numbers should you be most concerned with? Well that all depends on what you’re buying solar control film for. Is it fading, one-way visibility, or just plain heat. This data can help you figure out which film product will work best for your needs.

The technical data above is for 3M’s Interior Prestige Window Film Products, and since most of us are looking to add film to double paned clear glass, we’re going to use those numbers in our examples below.

The First Number you’ll notice on Prestige or any window film card for that matter is a number following the name of the product. This number roughly represents the amount of visible light transmitted, and this is generally true for most window film manufacturer’s products.

Product Name = Visible Light Transmitted (The higher the VLT, the lighter the film). If you want to add a film that will not change the look of your glass, you’ll want to choose a window film with a high VLT, and probably not anything with a VLT under 45%.

• Prestige 70: 62% VLT

• Prestige 50: 45% VLT

Now that we know why a film is called Prestige 70 or Night Vision 15, we can easily decipher which film products will change the appearance of our glass. If you don’t want to darken your glass, this will limit you to films with a VLT of 45% or higher. If you don’t mind darkening your windows, you’ll have an even wider variety of options.

Once you’ve settled on how dark or light you want your window film, you’ll be able to utilize the technical data to find the perfect window film for you. Below are explanations of what all the acronyms and data mean.

Visible Light Reflected Interior: This is the amount of reflection the application of window film will add to the interior side of your glass.

Many window films will have a high interior reflection, some can even cause a mirror effect, especially at night. If you want to see out of your windows at night, you should probably stay away from window films like 3M Silver P18 series with high interior reflectivity, and opt for products with low interior reflectivity like 3M Night Vision series.

Visible Light Reflected Exterior is the amount of reflection the application of window film will add on the exterior side of your glass.

The higher this number the more reflective your glass will be. This is an important number to look at if you are wanting to add film for daytime privacy. Prestige 70 would not provide this for you, you’d need to look at a film with a VLR Exterior of at least 20%, like one of 3M’s Night Vision products.

• Prestige 70 VLR Interior: 13%

• Prestige 70 VLR Exterior: 15%

• Night Vision 15 VLR Interior: 11%

• Night Vision 15 VLR Exterior: 39%

SHGC (Solar Heat Gain Coefficient): The lower the number means the better the heat reduction performance.

• Prestige 70 on Double Paned Glass: 0.56

• Prestige 50 on Double Paned Glass: 0.53 (Prestige 50 blocks more heat than Prestige 70)

Solar Heat Reduction: This is the estimated reduction in heat transfer with the application of window film. The higher the number, the less heat transferred through your glass.

• Prestige 70: 21% heat reduction when added to basic clear double paned glass.

• Prestige 50: 25% heat reduction when added to basic clear double paned glass.

UV, Ultra Violet Light Rejected: All Window Films will reject 99.9% of the UV Light. This is because the UV inhibitors are the in the adhesive. UV is the main cause of fading.

Glare Reduction: The percentage of glare reduced with the application of a particular window film product. The higher this number, the better the film works at reducing glare. If you are looking to reduce glare in your home or office, you’ll probably need to look at a window film with a glare reduction value of at least 50%, like one of 3M’s Night Vision products to have any real benefit.

• Prestige 70: 22% Glare Reduction

• Prestige 50: 44%

• Night Vision 35: 60%

• Night Vision 15: 82%

All info provided in this BLOG is for educational purposes only, and does guarantee specific performance of glass after window film application. Numbers and estimated performance are based off provided 3M Technical data, tested using the application of 3M Solar Control Window Film on Double Paned Clear glass with an estimated SHGC of .70 prior to installation of noted window films.

"How Much Does Window Film Cost?

This question comes up a lot here at Solar Vision, and I’m sure other window film companies too. Aside from being asked by customers when they call, it’s usually one of the most popular searches when people click on our Google Ad. Unfortunately when a customer clicks on ours or any window film page, the answer is not clear at all, and most likely not available. Why is this? Why isn’t window film pricing transparent? The short answer is much like carpet or tile, there are so many variables that can change the price you’ll be quoted. However via this BLOG, I’d like to at least help you answer the question as to whether or not the average price of having film applied to your basic window is of value to you.

As a window film dealer, I’m biased. I think window film is a no-brainer. Why? Well, because it can be one of the most important home improvements you can make. Window Film is there to protect you, and your home from heat, glare, and UV Rays. This can save you on your energy bills, make your house cooler, and more comfortable, while reducing the fading of your furniture, flooring, and window coverings. With all these benefits why not look more seriously into window film?

Unlike other home improvements window film is inconspicuous. This might make it a more difficult purchase psychologically, because you don’t see or notice this passive system once in place. It’s not super fun like a new 72 inch TV with Dolby surround sound, or a new couch you just purchased at Room and Board. No one is going to really notice your new window film, like they would notice a new sofa, or 72 inch TV. Your Mother In Law probably won’t comment on your new window film. However, she might comment on how much more comfortable and cooler your house is.

Example of Double Hung Window

Okay, commercial over. Let’s go back to the price. Window Film is generally charged per square foot, it seems odd, but most of the time, your square foot price is all-encompassing. It includes the material, labor, tax, and all the other cost associated with running a business, those items coupled with the hopes of making a profit is accounted for in your total price. Without going into all the math, let’s just say on average you’re probably going to pay between $15-$20 per SQFT to have solar window film installed. Window film is going to run you between $200-$400 for a basic double hung window, dependent on product type. This is about the same price as quality window coverings, which will most likely fade and ruin over the course of a few years without window film. I digress…one more plug.

These numbers are not absolute by any means, and different companies may charge different prices dependent on their cost of material, labor, and whether or not they have overhead like rent, and insurance (I highly recommend using a company with insurance). However I hope this helps get you closer to making that phone call to have your windows tinted.

Please also keep in mind other factors, like french panes, these windows will cost much more than a standard double hung window, or architectural windows that are large, and may require special equipment to reach, like the ones pictured below. These are all variables that could add additional cost to your window film installation. There are also variables that can lower the cost, like total square footage. The more the merrier in the window tint world. This means the more windows you have filmed, the more likely your are to receive a square footage discount which will lower your per square foot price.

Much like carpet or tile, what you pay and what your neighbor pays can vary. That’s because window film is a custom project specific to your home or office.

Call Solar Vision today at 303-862-6376 to schedule your window film estimate. Or if you want a quick turn around on pricing, you can always email us with photos, and measurements of your glass at info@coloradosolarvision.com , and get an estimate back from Solar Vision within 24 hours.

3M Daylight Redirecting Film

It was approximately 6 years ago that I gave my first Day Lighting Presentation for an Architectural firm in Aspen, CO (rough life, I know). The presentation was in an effort to promote 3M’s Daylight Redirecting Film, their newest product at that time. While the original product came with a few hiccups, over the years 3M was able to develop it into a simple adhesive application for clerestory glass (upper windows) . Reception for this new product was great, at every Architectural Event, Daylight Redirecting Film samples and brochures flew off the table. It was a cutting edge application that we thought would be all over architectural specifications in the coming years, however we were wrong.

What happened? Why isn’t Daylight Redirecting Film on every school, recreation center, box store, and building of any kind receiving direct sunlight? Why haven’t these revolutionary technologies caught on? In my opinion, rough timing. Unfortunately the debut of products like Daylight Redirecting Film were overshadowed by tragic events that brought security film to the forefront. This was good and bad. While it’s been good for business and has added a layer of safety and security to many projects, it’s halted the original driving force of our industry which is energy reduction, and efficiency.

90% of the Architectural Presentations I’ve given in the past 5 years have been on Safety and Security Film. I hope that in the coming years this will start leaning towards energy efficiency again. Security films have brought a new found popularity to the window film industry. My hope is that we can use this popularity as a way to bring more attention to the energy efficient window film products that 3M and other manufacturers have developed over the years.

While it’s been 6 years, our excitement for these products hasn’t changed. Solar Vision Inc. just completed another Daylight Redirecting Film project at a bank here in Denver, and the outcome is amazing. 3M Daylight Redirecting Film is a product that reaches beyond my expectations of what window film can do.

At Solar Vision , we believe that almost every business and building can benefit from 3M Daylight Redirecting Film. Along with utilizing the sun, a natural resource to provide interior lighting, it is also the only window film product on the market that can eliminate glare, without eliminating the light. Check out the video below to learn more about 3M Daylight Redirecting Film, and call Solar Vision Inc. 303-862-6376 to learn more about all the energy efficient window film options we offer.

WINDOW FILM IN THE WINTER?

Definitely! The winter can be some of the most intense sunshine of the entire year. Especially for those south facing windows. Some homes with large picture windows can even become uncomfortably hot in the winter. Along with heat, the winter glare can be incredibly intense. Plus, UV rays don’t care about the temperature outside. They’ll cause just as bad, if not worse damage and fading to your homes furnishings and window coverings in the winter, as they do in the summer.

Depending on your situation you have many window film choices. If heat and glare are your main issue, then a traditional window film will work great. However if you’re also looking to retain the heat in your home while blocking the heat during those intense part of the days an insulating film might be what you need. An insulating window film like 3M Thinsulate will make your home more efficient 24 hours a day, 365 days a year.

Solar Control Window Film is a necessary upgrade for any home, any time of the year, and there is no better time than the winter time to make your home more comfortable year round.

3M Daylight Redirecting Film

Imagine using a free resource to light your home or building? Well now you can using 3M Daylight Redirecting Film! Clerestory glass and other high up windows can cause a lot of heat and glare, which results in a nuisance below.  You can reduce the glare by using a typical solar control film, however, if you want to make the most use of your free natural resource you can use 3M Daylight Redirecting Film instead.

3M Daylight Redirecting Film takes the sunlight and guides it to the center of the room, instead of straight down. 

Below is an example of 3M Daylight Redirecting Film at work from start to finish. The pictures were taken at a local Denver bank. The lobby has a beautiful tower with large windows to allow in natural light. Unfortunately that light was causing a lot of glare issues in the lobby for the customers and employees below. After completion the light is now where it should be....up above!! 

Visit our DRF page for more info on this awesome new product by 3M! http://www.coloradosolarvision.com/3m-daylight-redirect/

This is a great photo to highlight what was happening with the light before 3M Daylight Redirecting Film was applied. This was still early in the day, so you can imagine where the sun glare ended up in the afternoon. In the eyes of everyone below! 

These high windows required a scissor lift for the application of 3M Daylight Redirecting Film! This photo highlights the soothing frosted appearance of 3M Daylight Redirecting Film. 

Here's a partial application of 3M Daylight Redirecting Window Film. As you can see the windows on the right are receiving the most sun during this photo, and the light is directed up. 

Here's an unaltered photo of the completed look. The 3M Daylight Redirecting Film has stopped the glare and downward direction of the sun's rays. Now the light is directed to the center of this tower allowing a beautiful glow to illuminate the lobby area of this bank.

Solar Control for Apartment Living

Solar Control for apartment living can be achieved through the use of a variety of solar control window films.  I have seen a number of apartments that get a lot of sun have all kinds of things in their windows to make it more comfortable.  I've seen cardboard, newspaper, sheets, and even a mattress.  Rental  property owners may ignore this or pose fines, but ultimately it affects the value of the property.  Solar control window films can greatly reduce the amount of sun and glare coming into a room.  Because it eliminates 99% of the UV rays, furnishings are not damaged.  It has the added protection of reducing the risk of skin cancer. Apartments usually are fitted with single layered glass.  Applying window film will give the window the effect of being double layered glass.  This would result in energy savings.  If a rental property company is energy conscious, it could advertise as making these changes to help save energy.  Solar control window film is especially valuable in those areas that get direct sunlight especially in the loft apartments on the top floors.

Window film is an relatively inexpensive way to make apartment living more comfortable.  Window film is easy to clean.  It is cleaned as any other window after 30 days.

3M Night Vision 15

3M Night Vision 15 was applied to windows in this home in Arrowhead.  3M Night Vision 15 is used when the clients want a darker film that lets in the least amount of light.  The views from this gorgeous mountain home are still maintained.  The film helps the occupants to be more comfortable in their home and blinds or other coverings may not be needed.  This depends on the amount of light entering the home and the desires of the owners.  In some cases, blinds may still be needed during certain times of the day. (solutions.3m.com) Night Vision 15 is the darkest of the Night Vision Series.  Its low reflectivity leaves the view from the home more clearer than ever.  This is wonderful especially in homes which are purchased because of the spectacular views in mountain homes.

3M Night Vision:

• Is easy to maintain
• Can be cleaned as any other window after 30 days
• Does not inhibit wifi or other electronic signals
• Gives daytime privacy, with the ability to see out at night

• Lets in 35% of light into the home
• Has an abrasion resistant coating for added durability
• Is covered by 3M warranties

Window Film Uses in Churches

Window film uses in churches add to their beauty, safety, and energy efficiency. There are few things more beautiful than a stained glass window.  The window creates a worshipful environment and help to set the tone in the church building.  Stained glass is very expensive and not all churches have the resources to have them.  Window film can be used in place of stained glass to give the church the atmosphere it wants.  Traditional art can be used or modern art can be used.  Any picture or any graphics can be imprinted on the film and put on the glass at a fraction of the cost of stained glass. The picture can be on one side or both sides.  A picture can be made so that one can see through the glass on one side and have the picture on the other.  Logos and murals can be put up on any flat surface of the church.  Some churches are mixing new art with the more traditional art.  New technology is used to create whatever look the artist imagines.

Bible versus can be used to remind people of messages the church wants to emphasize.

Privacy can be added where it is needed in the church using Fasara frosted film.  So many looks can be achieved through the use of Fasara films. Computer aided design techniques are used to plot and cut the film.(solutions.3m.com)

Solar control window film will cut down on energy costs and if there would be film breakage  because of something like a weather event, the film would hold the glass shards together and prevent injuries.  The film cuts down on glare and protects furnishings from harmful UV rays.

Unfortunately, sometimes churches are targeted by vandals.  Anti-graffiti film can be placed on signage or windows to prevent vandals from ruining the sign or glass.  Safety and security film can be put on glass to prevent break-ins.  Because some of the time no one is in the church, the church may be a target for robberies or vandals.  The films give an extra layer of protection.

The window film is used in retrofitting situations as well as new construction.  It is easy to clean.

Our Solar Vision mission is to inspire a passion for and generate living and working environments that are comfortable, safe, energy efficient and innovative.  If you have any design needs, comfort, and/or security needs in your church, please call Solar Vision.  Our staff will work with you to meet your needs.

3M Prestige 60

3M Prestige 60 was applied to this home.  The film was applied to the bottom window and the top window had not been applied yet.  This is a picture that represents well how the view of a window is maintained.  3M Prestige 60 is the ultimate in window film technology.  It consists of over 200 layers and is as thin as paper.  The technology used is called nanotechnology.  The folds cannot even be seen using a microscope.  These folds bend and catch light to create a film that produces the effects out clients want. (solutions.3m.com) 3M Prestige 60:

• Reduces the amount of energy used to cool a home
• Eliminates over 99% of UV rays which damages furnishings and is a cause for skin cancer
• Is less reflective than class, so it enhances views
• Is nonmetallic and does not interfere with cell phone or wifi signals
• Increases personal safety by  holding together shards of glass in the event of something that would cause the glass to shatter

3M Prestige 60 is covered by the 3M Lifetime Warranty.

Exterior Prestige Window Film

Exterior Prestige Window Film is made using nanotechnology.  The film consists of over 200 thin layers and is the thickness of a piece of paper.  This technology allows the film to provide superior heat control and glare reduction while preserving exterior and interior window views.  The film contains no metals so it does not interfere with wireless signals.  It is used in areas that are difficult to film from the inside.  If there is furniture that is difficult to move or permanent fixtures that make it impossible or near impossible to put on a film from the inside, then Exterior Prestige Window Film is the solution. Exterior Prestige Window Film might also be used if there is a high likelihood of breakage of a particular type of glass. With the exterior film, the sun does not heat the glass. (solutions.3m.com) Exterior Prestige Window Film:

• has a strong scratch resistant coating
• not self-cleaning, but repels water
• has virtually no chance of glass breakage
• can be used on dual or triple pane glass
• has high heat rejection with high visible light transmission
• comes in Prestige 40, 70, and 90

Colorado 2nd Place in LEED Certification

The state of Colorado achieved 2nd place in LEED Certification.  Congratulations, Colorado!  A new report by the US Green Building Council reported recently the top ten states with the highest ratings.  The rating system calculates the square feet of the space that is LEED certified and divides it by the number of residents that live in the state.  The measurement is a way to indicate how states are moving toward green building. Illinois was rated number 1 gaining a score of 3.3.  Colorado received a rating of 3.2.  Illinois and Colorado are the only 2 states that have been in the top 10 over the past 5 years.  This type of measurement began by the US Green Building Council 5 years ago.  If it were a state, the District of Columbia far surpasses the ratings of any of the states. (www.tripudit.com/2015/02)

LEED is used throughout the world to evaluate green building systems.  The top rating is a Platinum rating. There is also a Gold rating.  A Silver rating has recently been included so that more buildings can be rated at a lower cost.  LEED certified buildings use less energy and water, reduce carbon emissions, save money, and create a healthier environment.  There are a lot of things that builders have to do to acquire points for this ratings. This information is available on the USGBC website.

A few of the buildings in Denver which have received a platinum rating are:  1800 Larimer, NREL Research Support Facilities, Signature Centre, and Williams Village at the University of Colorado.  A list is available on the web.

Energy Savings with Window Film

Energy savings can be obtained with the use of window film.  Window film reduces the amount of heat that enters a room.  Less energy is required to cool the room.  In the winter, the film acts as an extra insulation on the window, reducing heating costs. LEED credits can be obtain by using window film.  The number of points that are obtained, depend on the amount of energy saved.

The goal of this credit is:  Achieve increasing levels of energy performance above the baseline in the prerequisite standard to reduce environmental and economic impacts associated with excessive energy use.  (www.3M.com/windowfilm)

There are 3 different methods for achieving this requirement.  Up to 10 credits can be obtained depending on the amount of energy savings. For specific information on the methods see the sustainable design information sheet in pdf form on the 3m web site:  multimedia.3m.com/mws/media/6636910/sustainable-design-information-sheet.pdf

Window film is a first tier technology that can have an approximate 3 year payback for buildings.  Window films are ranked in retro-fitted building envelopes as having the highest probability of success.  It ranks above replacement windows. Already existing materials are used decreasing the amount of waste. (https://promo.3m.com/assets/3MCAN/1202511082.pdf)

Window Film Reduces Light Pollution

Window film can aid in reducing light pollution.  In creating buildings that are environmentally and socially responsible, designers seek LEED credits.  LEED is a building certification program developed by the US Green Building Council. Credits are given for new building construction and major renovations. There are 9 possible points a building project can achieve through the use of window film.  One credit can be earned in the area of light pollution reduction. Light pollution is misused light or misdirected light.

 The light pollution creates:

• Sky Glow which is a hazy glow over urban areas caused by light escaping into the night sky.
• Glare shining into the eyes of pedestrians or drivers.
• Light Trespass which is light shining into a neighboring buildings.
• Light clutter such as in the area of Las Vegas casinos.

Light pollution effects all of us by:

• Consuming valuable natural resources.  Hundreds of millions of coal and oil are used.
• Polluting through the use of fossil fuels.
• Disrupting nocturnal wildlife.  One example is the baby sea turtles in Florida who move toward the artificial light on the beach instead of the natural light of the moon's glow that leads them out to sea.
• Affecting human health by disrupting circadian rhythms and melatonin production, depressing the immune system, and disrupting sleep patterns.
• Destroying the enjoyment of the view of the starry night sky. (www.starrynightlight.com)

Window film is not the cure for all those things, but it can play a part.

The goal of the credit for Light Pollution Reduction is:

Minimize light trespass from the building and site, reduce  sky-glow to increase night sky access, improve nighttime visibility through glare reduction, and reduce development impact on nocturnal environments.

One way window film can meet this requirement is to reduce the amount of light passing through a window from the inside to the outside by up to 85% while minimizing the reflection from the interior lights. Even at night an amazing view can be maintained.  (multimedia.3m.com/mws/media/6636910/sustainable-design-information-sheet.pdf)

To see if a project qualifies for this credit most of the internal light has to fall within the building.  Luminosity measurements are taken outdoors with all the lights off and are compared to the measurements with all the lights on. The credit is achieved if the outdoor illumination level does not increase more than 10 % with the lights on.  Window films with lower visible light transmission ratings will greatly reduce the light trespass from the buildings.

Our Solar Vision representative can help you find the right film that can meet your needs for reducing light trespassing.

3M Window Film Saves Art Studio

3M Window Film saves art studio located on an Iowa historical farm.  When straight line winds hit the farm house, the windows in the art studio located in the southeast corner of the home cracked.  The windows, however, held together because of the window film.  If the rain had gotten in the house, precious art work which could not be replaced and expensive art supplies would have been lost.  The window also stayed in place for a period of time until the window could be replaced.  Injury and damage due to flying shards of glass was eliminated. The owner is an artist and interior decorator.  She knew that her antiques, furnishings and artwork was being protected everyday from the harmful effects of UV Rays by the window film applied to all windows of the house.  The film also reduced glare and provided privacy.  The windows did not have to be covered with drapes.  The beautiful landscape of this home was not diminished by blinds or other window coverings.  She was also able to use less energy in cooling her home. The window film provides extra insulation to the windows. For example, if you have single-paned window, the film would make the window perform like a double-paned window.

The owner is so thankful she had the window film applied to her windows.  The loss due the weather event would have been great.  Insurance can't replace property with sentimental value or creative property.

School Comfort and Window Film

School classrooms that are  comfortable are more conducive to learning.  The first consideration for window film is school safety. (See previous article)  Window film can be used in a number of ways to improve school comfort, make learning easier, and save energy as well. Comfort and Energy Savings

During my 34 years of teaching, I have been in a number of buildings.  All of those buildings have had hot spots.  There are rooms where the sunlight coming into the room is unbearable during certain parts of the day. It is distracting to be in a classroom that is overly hot. To keep those rooms at a temperature that is somewhat comfortable, the air conditioning has to be turned up. Many of the rooms in the school are then too cold and students need their sweaters or just shiver.  A hot room does not help students concentrate on their studies nor does a cold one. More schools are going to a year round schedule, so they have to deal with even more summer heat.  Solar Control Window film applied to classroom windows reduce the heat entering the room.  Not having to lower the thermostat, saves energy.  In winter, the film acts as an extra insulator on the window.  Savings is realized in the winter also.  The US Department of Energy says a third of a building's cooling comes from solar gain through the windows.  Window film will make the windows more efficient.  (http://solutions.3m.com/)

Window film also eliminates glare on whiteboards.  The film protects occupants from harmful UV rays which can cause skin cancer.  Some rooms may require a combination of window film and blinds.  When the blinds do not have to be closed, natural light enters the classroom.  Students learn better in natural light. Eyes get less tired.

We know that students learn better in natural light.  Attendance and behavior is also improved. (http://www.healthyschools.org/Daylight.pdf) Window film still allows natural light.  A new 3M Window Film is 3M Daylight Redirecting Film.  If you have just the right space, the film brings in more light at the top of the window and redirects it to the room.  This lessens the need for artificial light.

Mirrors or Perforated Graphics

I worked in some areas where we took data on the behavior of students.  Graphics or mirrors can be put on  the window to observe students undetected.  The graphics are made with tiny dots. On one side you see a picture.  On the other side you can see through.  A mirrored film can be put on a window and from the other side observations can be made.  This could work well when the dean's office has a window to the cafeteria.  The possibilities are endless in the school.

Smart or Switchable Film

A smart film can be turned on and off.  When it is on the film is frosted.  When it is off the window is clear.  Think of the many uses for offices like the principal's office. He/She can see what is going on when it is off and can have privacy when he needs it for conferences with parents, teachers, students, etc.

Sports Viewing Rooms

Black out film can be used in athletic viewing rooms to eliminate screen glare.  Solar Vision has installed this at a number of colleges and universities.

Anti-Bacterial

A film that is not a window film, but is an architectural film is Di-Noc.  Some Di-Noc contains silver which cuts down on the growth of bacteria.  In areas, such as the nurses office and preschool classrooms, the film applied to smooth walls may help reduce the spread of germs.

Solar Vision can do a study of how window film can save energy and help you plan ways to use window and architectural films in your school.  If you would like a study done, give us a call at 303-862-6376 or e-mail us at info@coloradosolarvision.com.

3M Daylight Redirecting Film

At the 3M Conference in Puerto Rico, 3M introduced its new product 3M Daylight Redirecting Film, which is intended to help create green buildings.  The 3M Daylight Redirecting Film uses micro-replication to redirect the light that would have originally hit the floor a few feet from the window.  The light is directed to go up to the ceiling and then be reflected off the ceiling to light the room as far as 40 feet from the window.  About 80% of the light is brought into the room.  This reduces the need for artificial light during the day.  The natural light coming into the room increases productivity, people buy more, and reduces the need for electric lighting.  This energy efficient new window film technology can be used in retrofitting as well as new construction.   It is generally a commercial window film. The Daylight Redirecting Film is installed on the south, east, and west facing windows and is installed above a sill height of 6 feet to keep the sunlight out of the eyes of the people in the building.  The appearance of the glass with the redirecting film has the appearance of frosted glass.  The window film still keeps out harmful UV rays and stops glare and fading.  Some of the same benefits could be gained by putting a shelf on the window frame that reflects the light.  This shelf is not very attractive and is difficult to clean.  The window film is attractive and can be cleaned like any other window.

3M Daylight Redirecting Film will increase the sustainability and tenant satisfaction of a building.  It can be an effective energy management tool.  For specific information on how to use this new technology, contact  a Solar Vision Inc. representative.
