Silex Fiberglass Windows
Custom Shape Windows
Fiberglass windows and doors are not only energy efficient and strong, they will give a lifetime of performance while looking great in any application.
* SHGC – Solar Heat Gain Coefficient
Shading Coefficient = SHGC / 0.87
*LSG – Light to Solar Heat Gain Ratio
Performance values are based on 3 mm Glass COG
High Dimensional Stability
Fiberglass expansion rate is nearly identical to the rate of glass. This low thermal expansion rate translates into virtually zero seal failure. Which makes the entire window system and weather stripping more airtight. Internal stresses are reduced because all the components are expanding and contracting at about the same rate.
