Guardian Industries of Auburn Hills, Mich., is gearing up for the launch of a brand new product. Designed to provide not only comfort and energy savings, but fade protection from ultraviolet (UV) rays as well, ClimaGuard SPF™ will be officially unveiled at the Builders Show in January.

According to Tim Singel, Guardian’s director of residential glass products, homeowners consistently must deal with the problem of household damage caused by the fading energy of the sun—UV-A rays.

“Fading is the result of a combination of UV radiation, as well as fluctuations in temperature and humidity,” said Singel. Low-E glass, he explained, is already used in the majority of residential windows in the country, but does not address UV-A rays, which are primarily responsible for damage (i.e., fading). 

Recognizing the need to offer a product that addresses this area, Guardian began developing its ClimaGuard SPF glass. The company looked at a variety of products, including standard clear glass, spectrally-selective low-E, laminated glass and after-market films, in search of a solution for fade management.

“None of the scenarios were commensurate with performance and cost,” said Singel, “so we had to find another solution.” That’s when they chose to visit the textile industry. Singel explained that the American Association of Textile Chemists and Colorists offers a reference standard that can determine the relative color fastness of fabrics—ISO 105-B01 Textiles-Tests for Color Fastness. The test involves a wool cloth, colored with blue dyes that have varying degrees of colorfastness. Light is filtered through a variety of window configurations onto the cloth in order to compare the UV blocking ability of the different products. A control sample—black paper over the glass—was also tested. 

According to test results, the blue wool sample protected by ClimaGuard SPF resulted in an imperceptible change in color after 40 days in accelerated testing when compared to the control sample.

“ClimaGuard SPF delivered nearly the same results as the control sample,” said Singel.
Test results show that ClimaGuard SPF offers 99.9 percent UV-blocking protection compared to low-E’s 76 percent and 43 percent with clear glass. It also offers a daylight transmittance of 69 percent (low-E, 71 percent) and 11 percent reflected glare (low-E, 10 percent). Other results showed a U-factor of 0.24 (argon) and solar heat gain transmittance of 0.38.

While the official product release is not until January, Guardian has actually been selling it for two years to Beta test customers.

“We’ve been very pleased with the Beta trial,” said Singel. “We’ve been working closely with a number of high profile window manufacturers and we are very pleased with the progress.”

ClimaGuard SPF is designed primarily for the residential window market, but Singel said it does have an appeal as an architect-specified product as well.

That’s So Cool
Pittsburgh-based PPG Industries has introduced Vistacool™ Azuria™ glass. Vistacool Azuria, which has a luminous aqua-blue tint, is a high-performance glass that offers high visible light transmittance and an understated reflectivity that PPG says is more “muted” than “mirror-like” traditional, reflective glass.

PPG says it is also testing the Vistacool Azuria second-surface pyrolytic coating on other spectrally-selective and performance tints, including its Caribia® and Solargray glasses.

Can I Get a Lift?
The Wood’s Ladder Lifter is now available from C.R. Laurence Co. Inc. (CRL) of Los Angeles. The company says the new product offers a fast, efficient way to install above grade windows without staging scaffolding.

With a 375-pound minimum weight capacity ladder, the lifter clamps onto the rungs with the pulley assembly on top and the breaking wench assembly near the bottom. An adjustable hand-cup lifter bar, with two metal handle vacuum cups that attach to the window glass, is suspended from the galvanized steel cable. Using a second ladder, the installer can fit and seal the window.

The lifter has a load capacity of 185 pounds with an ANSI type 1AA 375-pound ladder. Two 8-inch Wood’s Powr-Grip Hand Cups are also required to operate the unit.

Staying on Guard
GE Advanced Materials of Pittsfield, Mass., has expanded its safety and security product line with three new transparent armor laminates for glazing applications: Armorguard™, Suregard™ and Lexgard™.

According to information from the company, these new laminates are designed for applications ranging from buildings, armored vehicles and detention centers to schools, power plants, and embassies. 

The products have also been tested to absorb 57 psi, and may also withstand gunfire from weapons ranging from 9-mm handguns to 7.62-mm NATO high-powered rifles, according to the company.
