Fiberglass is a natural insulator because it does not conduct heat and cold, and it doesn't expand or contract. Most window and door frame components have an interface of different materials: glass on wood, glass on aluminum or glass on vinyl. With fiberglass, the components are identical which means there is minimal expansion and contraction and if there is any, the components expand and contract as a unit.
PULTRUDED FIBERGLASS IS AN EXTRAORDINARY MATERIAL WITH SUPERIOR PERFORMANCE CHARACTERISTICS WITH THE FOLLOWING RECOGNIZED MATERIAL ADVANTAGES:
STRENGTH – A well engineered FG window delivers vastly superior strength characteristics when compared to other windows like PVC FG provides 8 times greater sheer strength when compared to PVC.
LOW MAINTENANCE – FG is the most stable material which provides an ideal base for a full range of finishes, ensuring an unbelievably durable window. This material is so tough that it will withstand extremes from Arctic cold to blazing desert heat to the rugged seacoast!
CONDUCTIVITY – FG combines strength with very low levels of conductivity, without adding thermal breaks. FG is an amazing 500 times less conductive than aluminum and FG frames and sash are also less conductive than vinyl due to reduced mass.
ENVIRONMENTALLY FRIENDLY – FG not only features the lowest embodied energy (low energy consumption in lineal production) when compared to other common window frame materials while providing and the longest life expectancy. This has led experts to recognize FG as the most environmentally friendly system.
NON-CORRODING – FG material is used in boats and bridge structures which face punishing loads and stresses as well as corrosive materials such as salt water. FG window frames provide superior life and durability to vinyl and aluminum in corrosive/coastal environments.
