Pyrolytic & Sputter Deposition Products
Low-E products improve the energy performance of an insulated glass unit in terms of U value and shading coefficients such as the solar heat gain coefficient or relative heat gain coefficient while allowing high visible light transmittance.
Low-E Coating Information
Two categories of low-E products are available: pyrolytic and sputter deposition. Both products have a thin metallic coating that reflects the infrared portion of the heat spectrum back to its source, retaining radiant heat created within a building and refusing exterior radiant heat.
Sputter coatings are applied in multiple layers to glass using a vacuum chamber. The advantage of this coating is the wide selection of materials that can be sputtered. These combinations provide nearly invisible coatings with the highest level of performance possible. Sputtered coatings must be protected inside a sealed insulated glass unit due to the relatively fragile nature of the coating.
Pyrolytic coatings are applied to hot glass embedding thin layers of metal into still-soft surfaces of the material before it is cooled on the lehr line. The coating is highly durable.
Glass Fabricators Inc. is currently a certified fabricator of Cardinal Industries and Vitro Glass low-E products. Please get in touch with us to see what low-E product is right for your project.
Cross Section
Construction:
Insulated glass units consist of two or more lites of glass separated by a metal spacer, filled with desiccant, and hermetically sealed with polyisobutylene as the primary sealant, and polysulfide or silicone as the secondary sealant. Units are fabricated to the requirements of the project in terms of dimension and components.
Desiccant:
Low deflection molecular sieve/silica gel blend
Spacer:
Laser wielded aluminum tubing
Primary seal:
Polyisobutylene
Secondary seal:
Polysulfide or silicone
Corners:
Crimped butyl sealed corner keys
Warranty
Glass Fabricators’ insulated glass units are warrantied against seal failure due to manufacturing defect for ten years. The warranty is dependent upon correct handling, storage, and glazing. It is the responsibility of the purchaser to comply with federal, state, and local building codes with respect to safety precautions, wind loading, and suitability. A copy of the warranty is available by contacting Glass Fabricators Inc. The warranty details terms, limitations, and remedy in the event of a claim.
