New Product Focus

 

fire-rated glass

In the Clear
Keralite Select is the newest innovation in fire-rated glass from Vetrotech Saint-Gobain, combining patent-pending surface polishing technology with what the company calls advanced composition to create “the sharpest, most accurate color-viewing glass ceramic in its class.”

As Kevin Frisone, Vetrotech’s sales and marketing manager, North America, explains, fire-rated glass ceramics typically have a certain level of haze. This new product, which has fire-ratings in 20, 45, 60, 90 and 180 minutes, was created to “have the lowest haze” compared to similar products on the market.

Keralite Select scored 97.1 out of 100 on the color-rendering index of 97.1, which, according to the company, is the highest R96a value for glass ceramics. It also has a haze value of 0.5 percent, which is the lowest available, according to Frisone.

Describing the product, Frisone says it’s both “higher performing and better performing,” providing clear, sharp images. “It provides a truer color,” he says, adding it also provides a high visible light transmittance, which can allow in an increased amount of natural light.

Speaking of the new glass, Frisone adds, “It provides function and aesthetics … allowing architects to be more creative …” For additional life safety, a surface-applied film is also an option.

Make Room for the VIP
Dow Corning and Okalux GmbH have collaborated to create the Okalux VIP, a high-performance insulation module that exhibits what the companies call excellent heat insulation, combined with nearly unlimited possibilities of design for every façade construction.

The vacuum insulation unit consisting of fumed silica integrated in the cavity of an insulating glass module is paired with a range of material inserts from Okalux.

Okalux VIP 40-mm thick elements can reach a U-value of 0.11 W/(m²K) | 0.02 Btu/(hr ft² °F), according to the company. The heat conductivity of a vacuum insulation panel is said to be approximately 0.005 W/(mK) and the heat transmission coefficient corresponds to that of a well-insulated wall, according to Okalux.

The thickness of the insulation modules corresponds to the constructive depth of typical glass units and individual, custom-tailored design solutions can be created. The vacuum façade elements are pre-fabricated and installed on site in the same fashion as standard insulating glass.

An Ideal Combination
Transparent, solar control, low-E glasses are elevated to new levels of clarity and solar control with Solarban 67 glass by PPG, according to the company.

Engineered with a proprietary double-silver, magnetron-sputtered vacuum deposition (MSVD) coating, Solarban 67 glass offers a vibrant, neutral appearance. Clear glass is standard, but it can also be specified with blue, green and earth-toned on the second or third surface of an insulating glass unit.

A Place in the Sun
Guardian Industries has announced the availability of its SunGuard SNX 51/23, a commercial low-E glass product with what the company says is a visible light transmission (VLT) above 50 percent and a solar heat gain coefficient below 0.25, in a standard insulating glass unit.

This new addition to the Guardian SunGuard portfolio of high performance, low-E glass, triple silver SunGuard SNX 51/23 has high visible light transmission, low reflectivity and a neutral blue appearance. The glass is designed to meet the most stringent energy codes in North America, according to the company.

SNX 51/23 is available on clear, green, UltraWhite, CrystalGray, gray and TwilightGreen substrates, in both annealed and heat treatable versions.

switchable glazing

An Innovative Switch
Innovative Glass Corp. is promoting its liquid crystal switchable privacy glass, also known as LC Privacy Glass, or eGlass®, which can be used in a variety of applications for intensive care unit (ICU) applications. The laminated glass has an electrified film imbedded within and switches from clear to frosted white at the touch of a button.

In the unpowered, default state, the glass is completely obscure, providing what the company says is 100 percent privacy from both sides while still allowing light to pass through. When electricity is provided, the molecules in the film reorient and the glass becomes clear.

LC Privacy Glass has no moving parts, and the lamination makes it virtually soundproof, according to the company.

This glass can be installed in fixed walls, partitions and sliding walls, as well as in swinging and sliding/breakaway doors found in ICUs and emergency rooms, among other types of projects. Wiring methods range from simple door loops to electrified hinges, or sophisticated and proprietary power transfer systems for the sliding/breakaway doors.

doors

Don’t Let This One Slide By
LaCantina Doors has created a new, multi-slide and full-range of swing doors.

Custom-engineered rolling hardware and AAMA-certified wheels provide a uniform, symmetrical, low-profile bottom rail, according to the company.

The multi-slide doors also feature the company’s narrow stile and rail profiles, the same used in its folding doors and new swing doors. The multi-slide offers weather-resistant and flush sill options, a minimal one piece handle and lock with an exterior key, an advanced seal system and is backed by the company’s 10-year warranty.
