NFRC Certification

V-Kool has recently learned that the manufacturer of V-Kool Window Films, Southwall Technologies, has had certain V-Kool films certified by the NFRC.

 

 V-Kool 75

Has most of the advantage of V-Kool 70 with less solar heat rejection. This product will give you the most clarity, with reduced heat rejection versus V-Kool 70.

 

V-Kool 70

Heat build up and nighttime or daytime visibility (looking out) are maximized with V-Kool 70 due to the high degree of clarity of this window coating. It is virtually clear. It is also well suited to reduce solar heat while maintaining architectural integrity.

V-Kool 65

Has similar advantage of V-Kool 70, but with less solar heat rejection and less clarity. It is a lower cost solution.

 

V-Kool 55

V-Kool 55 was developed to meet the IEC of .40 SHGC.  This product has solar properties in between V-Kool 70 and V-Kool 40.

V-Kool 40

When solar heat build up is the primary problem, V-Kool 40 maximizes solar heat reduction. V-Kool 40 is best suited for UV fade and heat buildup.

V-Kool 35

For solar heat reduction and glare reduction V-Kool 35 and 40 are your better choices.

 

The Technology Behind Our Products

Construction

V-Kool® was originally developed for America's Space and Defense programs. It represents an important breakthrough in surface and partical science. It works through a patented process known as sputtering in which tiny particles of exotic metals are embedded in optically clear, durable polyester film. We use a durable pressure-sensitive adhesive to adhere to the glass and on the other side is a durable Scratch Resistant coating to ensure a long life.

 

Spectrum Graph

V-Kool® is spectrally selective and allows in 73% Visible Light, while blocking over 90% infrared spectrum. This means your window remains Visibly Clear but cuts out 55% of the Solar Heat. No other product can match V-Kool®'s performance. When applied to your windows, V-Kool® forms a virtually clear barrier. That means less need for expensive air conditioning and electric lighting, making V-Kool® a great way to help control soaring energy costs.

Popular Science

It's True! V-Kool®'s spectrally selective technology has been voted as one of the Top 100 inventions of the Millennium, along side other essentials like canned food, the refrigerator, computer, insulation, internet and the telephone*.

"For years, windows were a big yawn. Sure, they let in too much cold in the winter and heat in the summer, but c'est la vie. But the introduction of new glazing systems in the early 1980's kicked off a surge in window technology that sparked such enthused descriptions as "Wonder Windows" and "Superwindows." Among the dramatic innovations were coatings that let in light but not heat; inert-gas filling between panes; and heat-stopping edge spacers. The Southwall Heat Mirror, a heat-retaining film, was one of the more dramatic advances."
