Borosilicate Glass for High Heat & Outdoor Applications
Gray Glass has offered fabrication and machining for the glass industry for over 60 years. Serving all industrial glass fabricating needs with precision CNC machining and water jet cutting services for cutting and sizing, hole drilling, glass polishing, laminating, etching and UV bonding. Gray Glass is also a complete source for architectural specialty glass stocking the largest selection available from anywhere nationwide. Gray Glass has antireflection laminated UV float and optical glasses with glass components manufactured to OEM specifications.
Now emphasizing our custom lighting products designed to meet your specs and now feature all types of specialty glass including high temperate borosilicate glass good for thermal shock resistance and flat glass for lighting design.
For Lighting Applications, borosilicate is a material of choice for high heat and outdoor applications. It is usually needed for safety coverings over hot fixture lamps and it is especially useful for landscape and architectural lighting, where a hot lens may be subject to thermal shock from cold rain or snow. Other Borosilicate glass available from Gray Glass are; Borofloat®, Alkali Free Borosilicate (7059 & 1737 glass codes), Furnace Observation Blue Borosilicate and Infrared Reflecting Borosilicate (IRR Borosilicate).
Borosilicate - A type of glass with main glass-forming constituents silica and boron oxide. Well know for having very low coefficient of thermal expansion (~5 × 10-6 /°C at 20°C). However, there are many different borosilicate glasses made with various expansion coefficients (e.g. Pyrex and Borofloat are 32.5 while 7059 is 49). The lower the coefficient of expansion the more resistant the glass is to thermal shock.
Since 1946 Gray Glass has been the front runner for precision glass fabrication and machining with an in-depth knowledge of industrial OEM, instrument and gage manufacturers as well as optical production experience for glass requirements. Improved precision water jet cutting and machining expands our capabilities to cut virtually any shape cutting a wide range of thickness to high tolerances for custom glass machined components.
Offering architectural glass solutions for commercial and residential lighting manufacturers, showcase and display, and custom furniture. Stage and theatrical lighting and colored glass filters are available from Devon Glass. We ship globally and service government, defense contractors, science researchers and architectural, residential and commercial markets.
