Glare Reducing Films:
What you need to know

Glare control is a simple matter of reducing the transmission of visible light.  This is exactly what you are doing when you put on a pair of sunglasses.   Installing Glare Reducing Window Film is like putting sunglasses on your windows.  The darker the film you select, the more light it will block and the more glare it will reduce.

Don't want to go too dark?  Concord offers a wide range of films to choose from, from light to dark.  Each film has a light transmission number (we call it VLT in our industry for Visible Light Transmission).  The lower the number, the darker the film.  For example, a 5% film transmits 5% of the light and filters out 95%.  A 20% film transmits 20% and filters 80%.  The higher the film number, the more light it transmits and the lighter it is.

Sometimes our customers have other objectives as well, such as fading, heat control and/or privacy.  Concord also offers multi-purpose films which will control glare as well as heat and Ultra Violet light to reduce the fading of fabrics and furnishings.

When choosing a film for glare control, consider the darkest film you are comfortable with.  It is a common misconception that some darker films "ruin the view".  In fact, the opposite is often true.   By way of example:  Have you ever driven your car on a sunny day wearing a pair of dark sunglasses to cut down on the glare?  Did you know that most good sunglasses "such as Ray Bans" actually block as much as 95% of the visible light?  Even with that much light being blocked, you can safely drive a car at highway speed.  Are the dark glasses "ruining your view"?  Of course not.  In reality, they are enhancing your view because they are blocking the excessive visible light (the glare) which can cause you to squint, making it harder to focus on well lit objects.

The reason for this is that the human eye pupil dilates and adapts to the reduced visible light.  You can filter out a large percentage of visible light and still see perfectly well.  Therefore, when it comes to choosing a glare reducing film, the darker the better.  It will not ruin your view any more than your sunglasses do when you drive on a bright sunny day.  The key is to find a happy medium - something that will control the level of glare and keep the light levels in the room at comfortable levels.

Special Circumstances:  Storefront Display Windows

Are you seeking to reduce the amount of light coming into a storefront display window?  In this case you have a slight dilemma.  In order to cut down on the glare, you need to block as much visible light as possible.  But installing a dark film will make it harder for your customers to see your display or to look into your business.  You will have to use a medium to lighter film.  Some reduction in performance will be necessary to preserve the view.  The key is to find a "happy medium".  If your storefront or business interior is very well lit on the inside, it will work in your favor.  If your lights are not too bright inside, you will have to consider something lighter.

Another important consideration is double pane glass.  The most effective glare reducing film are also the darkest and darker films absorb more solar energy.  We have easy to follow guidelines so that you know which films are approved for application to double pane windows and which are not.

Special Circumstances:  Glare on computer monitors or other viewing screens.

In some cases, you might have direct sunlight on monitors and/or displays making them hard to see.  In these cases, it may be necessary to not only use darker films, but to reposition and/or tilt displays and monitors so that they are not subject to direct sunlight.  Even the darkest films may not be enough if the sun is directly on the monitor or display.  The combination of the film and a slight offset works well most of the time.

Our "Featured Films" are the ones which are the most popular choices for glare control applications.  For those customers who prefer to select from a wider range of films, we list our entire glare control product lineup further down on this page.  If you have any questions along the way, do not hesitate to contact one of our solar control specialists.  Selling solar control window film has been our one and only business since 1982.  We will provide you with expert advice and guidance every step of the way.

What are the differences in each of these films?


Silver Reflective:

Silver Reflective Films have a “mirror like” appearance and can be excellent choices for glare control.  There are a total of 4 different films in the Silver Series (68%, 53%, 35% & 15) and all are approved for application to thermal insulated (double pane) glass units up to 40 square feet in size.   The lower the film number, the darker and more reflective looking the Silver Film is.  The most effective glare control film within the Silver Series is the 15%, which also has the benefit of reducing a large amount of incoming solar heat.  The lighter silver films (those with higher numbers) are not as dark and will not block as much glare or solar heat.

If you would rather avoid the visibly reflective look (mirror like appearance) there are other films mentioned below that can perform equally well with a lower amount of visible reflectivity.

Glare Cut Series:

These films are among the most basic and effective window films because of their simple and purposeful construction.  Glare Cut Series Films are designed to block visible light.  You can think of them as a pair of sunglasses for your windows.  The Glare Cut Series contains a total of five different films 70% 50% 35% 20% and 05%.  The lower the number, the darker the film.  The two darkest films in the Glare Cut Series are not approved for application to thermal insulated (double pane) windows.  The remaining lighter films in this series are approved for application to double pane window units under 40 square feet in size.

Glare Cut Films are a good choice if you are seeking to simply block excessive visible light.  Although they are not specifically designed to do so, they will block some of the incoming solar heat as well.  If you are seeking to block both glare (visible light) as well as solar heat, consider one of the other films that have additional layers designed to block solar heat.

Neutral Series:

These films are an excellent choice for combined glare control along with solar heat blocking.  Incorporated within them are the micro thin metallic layers that give the film increased solar heat control performance as compared to a Glare Cut Series Film.  The metallic layers are embedded between outer layers of tinted material, so the reflective surface of the metal is hidden behind a darkened layer – making it virtually invisible.  These unique multipurpose constructions are our most popular selling films.  They have a neutral appearance on the window and are virtually undetectable from the inside looking out.

Neutral Series Films are available in 3 different shades 50% 35% and 20%.  The lower the number; the darker the film.  The darkest film in the series (20%) is not approved for application to double pane windows.  The two lighter films (50% & 35%) are approved for double pane windows up to 40 square feet in size.

Dual Reflective Films:

When considered primarily for glare control applications, these films have few advantages over Neutral Series Films with the notable exception of the Dual Reflective 10%, which is the darkest and most effective film approved for application to thermal insulated (double pane) glass units up to 40 square feet in size. 

Sputtered Neutral Films:

These films are typically not used for simple glare control applications, but if solar heat reduction is a consideration they may be considered.  As these films contain no dyes or pigments, they are considered to be among the longest lasting films in the market.  Sputtered Neutral is available in 60% 45% 35% and 20%.  Except for the 20%, Sputtered Neutral Films are approved for application to thermal insulated (double pane) glass units up to 40 square feet in size.  Double pane units larger than 40 square feet in size should not be tinted.

Sputtered Copper Bronze Films:

These films have an attractive copper tone and may be consider for aesthetic reasons.  There are a total of three different films in this series 50% 35% & 20% and all are approved for application to thermal insulated (double pane) windows up to 40 square feet in size.  Sputtered Copper Films also have excellent solar energy control properties and may be considered for that aspect as well.

Ceramic Films

Because they are among the lightest films available, Ceramic Films are generally not used for glare control applications.  There are 4 films within the series 76% 68% 67% & 58%.  All of our Ceramic Films are approved for application to Double Pane glass up to 40 square feet in size.  Double pane windows larger than 40 square feet should not be tinted with ANY film due to the risk of thermal shock fracture or seal failure.
