Insulated Glass
The wide use of insulated glass spurred by the energy crisis of the 70’s is no longer the simple separation
of two panes of glass by a dead airspace. Glass and coating technology has evolved the humble IG unit into a
dynamic component of the energy equation so critical in today’s ever-increasing demand for efficiency and savings.
Add to this the ability to bring sustainability, local availability, and single source supply, and Arch insulated
glass and aluminum products are clearly part of the key to success.
Tempered Glass
All tempered glass products conform to the guidelines of ASTM C 1048, and comply with both CPSC 16 CFR 1201
and ANSI Z 97.1 -2004. Arch Aluminum is a self-certifying organization. Each producing plant routinely tests
to the aforementioned standards in house. In addition, hourly tests are performed under the GANA guidelines and
semi annual audits are performed by independent, nationally recognized laboratories confirming compliance to
the aforementioned standards as safety glazing.
Spandrel Glass
Spandrel is a convenient method of masking or covering construction areas. The basic premise in glass spandrel
is to render a glass substrate opaque in reflected light. Once installed this product provides a finished appearance
when viewing from the exterior. Arch Aluminum provides spandrel using the traditional ceramic frit pigments as
well as relatively new silicone coatings.
Laminated Glass
Laminated glass is traditionally defined as two or more lites of glass and one or more interlayer’s of polyvinyl
butyral (PVB) permanently bonded together under heat and pressure.
This union of materials provides a variety of performance benefits in architectural applications. Its most important
characteristic is the ability of the interlayer to support and hold the glass when broken. This provides for
increased protection against fallout and penetration of the opening. Laminated glass is generally 75% to 90%
as strong as annealed glass of the same thickness depending on exposed temperatures, aspect ratio, plate size,
stiffness and load duration. The ability of the interlayer to resist various kinds of penetration may also be
dependent upon thickness, temperature and other variables. Check with Arch for any additional limitations, such
as roll distortion, that may result from additional processing of laminated glass
