Pilkington Offers Low-Reflective Solution
Pilkington North America offers solutions for low-reflective glazing requirements
with its Special Applications glass products. The Special Applications
range includes low-reflective products for almost any application.
Among the options, Pilkington OptAR is a low-reflective, glare control
glass that can be used in technical applications. It reduces glare and
provides low reflectivity to minimize eye strain, and increases visual
acuity and allows for displays to be read more easily by reducing visible
reflections to less than one percent. It appears slightly blue-red in
color, which aids in glare control, and also shows that it is not a plain
piece of glass, allowing it to be successfully used in monolithic applications.
With its electrically conductive properties, OptAR can be used in applications
including touch panel displays, aircraft transparencies, flat panel LCD
monitors, televisions and other electronic applications.
OptiView is a color-neutral laminated glass with low-reflective coatings
on the first and fourth surfaces of the glass. The coating reduces the
interior and exterior visible light reflectance to less than two percent.
Views from the interior and exterior of a building are clear and virtually
reflection-free, making it suitable for a wide range of applications in
which clarity of view is of paramount importance.
Both options use pyrolytic coatings, making them durable and easily handled,
transported and processed.

U.S. Aluminum Introduces New Design Manuals
U.S. Aluminum, a subsidiary of C.R. Laurence Co. Inc., has published a
two-volume series of architectural design manuals. The manuals include
aluminum storefronts, entrances, window walls, windows, hurricane-resistant
and blast mitigation systems, as well as several other company architectural
systems. Every chapter contains a selection of complementary architectural
hardware plus all of the accessories required to ensure a professional
installation, according to the company.

Bystronic Glass Provides High-Speed IGU Solutions
Speed’sealer is the new high-speed sealing robot from Bystronic Glass,
designed for insulating glass unit production. The Speed’sealer seals
windows and façade elements at a maximum flow rate, and with a
high application speed. Due to its dynamic mixer it is possible, even
with different production conditions, to actively and consistently mix
the two-sealant material components. With consistent quality, the machine
seals double and triple insulating glass units at high-speed. This is
achieved immediately after production begins regardless of the sealing
material selected or variations in material quality or temperature.
The constant mixing ratio of the two adhesive components is monitored
electronically. The high-precision dosing technology ensures an accurate,
volume-controlled application of sealing material and immediately adjusts
volumes where the joint depths vary, according to the company.

Rainscreen Panel Extrusions Now Available
Southern Aluminum Finishing Co. Inc. (SAF) has introduced a full line
of panel extrusions to hang, join and secure rainscreen panels for curtainwall
applications. SAF panel extrusions work with the company’s panel wall
systems, or may be ordered stock length and finished to meet customer
specifications. The panel extrusions are part of the more than 200 other
extrusions SAF stocks for ready availability.

3M Films Add Light and Color
A broad range of new products derived from advances in 3M’s core technologies
offer helpful properties to glass makers. Among them, the Ultra-Clear
Solar Film, sandwiched between outer and inner lites, reduces solar radiation
by up to 34 percent with minimal reduction of visible light—especially
beneficial for retailers who require clear view of merchandise in storefronts
or façade designs that maximize natural light. The film reduces
heat streaming through the glass by selectively blocking infrared light.
This clear, low-reflective film is compatible with tinted, coated and
other types of glass; works with PVB, EVA and SentryGlas®Plus interlayers;
and, since it contains no metal, will neither corrode nor interfere with
radio frequencies of electronic devices.
A new daylight redirecting film was designed to bring natural light deeper
into the interior of the building by acting as a light shelf to redirect
the light while blocking ultraviolet rays, according to the company. This
cost-effective film redirects light toward the ceiling, reducing the need
for artificial light during the day. In addition, the versatile film gives
glass manufacturers and architects different aesthetic designs when applied
to different glasses.
Company officials say 3M’s dichroic films for laminated glass offer a
brilliant and unusual decorative look to architectural glass. The color
of the film changes from different viewing angles. Depending on the type
of film used, architects and designers can liven a structure with vibrant
hues of gold, blue, aqua, bronze or copper. These nonmetallic, colorful
films can be applied to low-iron, tempered and other glass types.

Fenzi Study Says Fabricators Can Improve IG Performance with Thiover
A study conducted by Fenzi North America highlights the importance of
a secondary seal in reducing gas leakage in insulating glass units (IGU).
The company reports that its laboratories demonstrated the superior performance
of its Thiover as a secondary seal versus normal silicones.
The company studied the improper application of polyisobutylene (PIB)
and the effect it has on an IGU using various sealants. Each unit analyzed
was given a 1-cm gap in the PIB on one side of the unit to see the affect
of the common deficiency. The units were then subjected to high humidity
testing where the temperatures were controlled at 60 degrees Celsius and
relative humidity at 98 percent.
The company reports that the study shows that polysulfide lost less than
8 percent of gas over 1,680 hours of high humidity and high temperature,
whereas silicone lost up to 20 percent from original gas filling in that
same time span. Several factors contributed to these results, such as
the physical gas retention properties of silicone and polysulfide, and
differences in mechanical properties of the two sealants.
