Cardinal Loå3-366reduces window heatgain by 64% comparedto ordinary glass.

750 insideWhen the temperature soars, ordinary window glass just can’t handle the heat.And tinted glass spoils the view. CardinalLoå3-366, however, has been specially formulated to reject the sun’s heat withoutaffecting the view. It lets more light in andkeeps more heat out. So your home stayscool and comfortable. Our patented Loå3-366 coating provides the ultimate inperformance and clarity of all our Loåproducts.

What’s more, Loå3-366 provides exceptionalfading protection as well. It blocks 95% ofthe sun’s damaging ultraviolet rays (aleading cause of fading), so it will helpyour furniture, carpets, curtains and wallcoverings stay beautiful for years to come.

During cold weather, the insulating effectof your windows has a direct impact onhow your rooms feel. Typically, 75% of theexposed surface of a window is glass, andthe temperature of the room-side of theglass directly affects the air temperature inthe room. The better insulated the windowglass, the warmer your room will be.

In fact, the Efficient Windows Collaborative(www.efficientwindows.org) suggests thatwhen glass surface temperature fallsbelow 52°F, there is a risk of thermal discomfort. To maintain the best comfortduring the winter, select a glass productthat produces surface temperatures thatwill stay above this point during the coldestoutdoor conditions.

It’s the perfect cold remedy,too.

The superior insulating capability of Cardinal Loå3-366 is akey factor in the construction of comfortable windows forcold climates. The dramatic comfort improvement fromwindows with warm glass surfaces also means the relativehumidity of the indoor air can be controlled and maintainedproperly. Proper humidity levels (not too much, not too little)will improve comfort and promote a healthier living environment.

Note: All values calculated using Window 5.2. (See http://win-dows.lbl.gov/software/window/window.html and http//windows.lbl.gov/materials/igdb/ for more information on glass optical dataand the Windows 5.2 program.) Emittance of ordinary low-e is 0.20.

Solar Heat Gain Coefficient – (SHGC). The amount of solar radiationthat enters a building as heat. The lower the number, the better theglazing is at preventing solar gain.

Fading Transmission – The portion of energy transmitted in aspectral region from 300 to 700 nanometers. This region includesall of the ultraviolet energy and most of the visible spectrum, andwill give the best representation of relative fading rates. The lowerthe number, the better the glass is for reducing fading potential ofcarpets and interior furnishings.

U-Factor – This represents the heat flow rate through a windowexpressed in BTU/hr/ft2/°F, using winter weather conditions of0°F outside and 70°F inside. The smaller the number, the betterthe window system is at reducing heat loss.

Cardinal actively supports and participates in The NationalFenestration Rating Council (NFRC). Windows with Loå3-366 thatare rated and certified by the NFRC can comply with Energy Star™

requirements for all climates in the country.
