New Product Focus
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
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
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
SNX 51/23 is available on clear, green, UltraWhite, CrystalGray, gray
and TwilightGreen substrates, in both annealed and heat treatable versions.
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.
Don’t Let This One Slide By
LaCantina Doors has created a new, multi-slide and full-range of swing
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.
