Why is SHGC important?

Solar Heat Gain Coefficient

The SHGC is the fraction of incident solar radiation admitted through a window, both directly transmitted and absorbed and subsequently released inward. SHGC is expressed as a number between 0 and 1.

The lower a window’s solar heat gain coefficient, the less solar heat it transmits. The nationally recognized rating method by the National Fenestration Rating Council (NFRC) is for the whole window, including the effects of the frame.

Alternately, the center-of-glass SHGC is sometimes referenced, which describes the effect of the glazing alone. Whole window SHGC is lower than glass-only SHGC, and is generally below 0.8.

Solar heat gain can provide free heat in the winter but can also lead to overheating in the summer. How to best balance solar heat gain with an appropriate SHGC depends upon the climate, orientation, shading conditions and other factors.

Anti Glare Window Film

Anti-glare window film is a special type of sun control film that helps eliminate a significant amount of unwanted sunlight and glare while allowing natural light to pass through. Whether it is the long sunny days of summer, the intensity of morning and evening sun, or the low-lying nature of the winter sun, the intense brightness and ultraviolet (UV) rays from the sun can pose a problem year around.

Compared to traditional solutions like blinds and screens, glare-reduction window film is a more cost-effective and easy-to-maintain solution that won’t obstruct or block your view to the outdoors.

Glare Control Window Film helps make it more comfortable to look at virtually any electronic device – even in the most sun-flooded room, at high noon. We help you to create the right environment.

Like the lenses in your favorite sunglasses, Our Glare Control film is easy to put on and reduces glare to help you see better, no matter what you’re viewing.

Anti-Graffiti Film

Vandalism can’t always be avoided but protecting your wallet in the midst of crime is something every store owner wants. The anti-graffiti film is a transparent layer of film placed on top of windows to prevent the need for full window replacements while continuing to keep the window’s views.

When vandalized, the film can be easily removed and replaced. The replacement cost is cheaper and more affordable than the need to replace the glass of the window.

Making the investment on anti-graffiti film now will save store owners from future headaches and economic loss

Is anti-graffiti film easy to install?

No. The most common problems that occur with the installation of anti-graffiti film are:

Peeling corners – the outer frames of windows hold onto a lot of debris. Even after several washings this debris will easily get sucked behind the edges of the film as it is being trimmed to fit the window. Not only does this produce a bubbly “rash” of grit behind the film, but weakens the bond between the film and the glass. Since the adhesives in anti-graffiti film are designed to be more easily removed, any amount of dirt that inhibits this already loose bond will result in the premature failure of the adhesive.

Wind – anti-graffiti window films are around 4 times thicker than average solar control window films. This means that even the smallest speck of dust will create a large bubble behind the film, because the film is too thick to mould around it. Storefront windows are big. To remove the liner on such a large piece of film, soak it with application fluid and get it onto the window without the wind catching the film or peppering it with dust is an issue every installer has to deal with, but only few are well experienced at preventing.

Does the brand of anti-graffiti film matter?

Not to the consumer. As long as you are using an optically-clear multi-layered film with at least 7-MIL construction for a glass thickness of 8mm or above and 4 Mil for less than 8mm thickness glasses, then you are good to go.

The major difference between each brand is how easy the film is to remove. This is something that matters more to the company installing (and some day replacing) the film. Some films remove easily while others come off in small pieces leaving a lot of adhesive behind.

How is anti-graffiti film different from security film?

The major difference is the adhesive. Security films are not meant to be removed and have an aggressive adhesive that is designed to hold the glass together in the event of breakage. The adhesives in anti-graffiti films are designed for easier removal.

Security film is meant to be installed on the interior surface of the glass and only has UV protectant in the adhesive layer of the film. Since anti-graffiti films are meant to be used outdoors, they have a UV coat on the exterior of the film in addition to the adhesive to prevent premature breakdown of the film.

Although some “safety” films come in thicknesses as low as 4-MIL, the most commonly used “security” thickness is 7-MIL, about 25% thicker than the most commonly used anti-graffiti film.
