Why Fiberglass?
Energy Efficiency
Energy Efficiency
Fiberglass is created by pulling strands of glass through a heated die, resulting in a material that is strong, resilient, and suited to all weather conditions. Essentially a carbon fiber product, it has been used for many purposes, including boats, satellites, bridges, and goalie masks, where it is subject to extreme temperatures and constant abuse.
Fiberglass can meet a wide variety fenestration needs, from design, to durability, to performance objectives.

Conductivity
Energy efficient frames have low conductivity that discourages the transfer of heat or cold into a building. Fiberglass has a much lower conductivity than metal options; simply placing a hand on a fiberglass frame compared to an aluminum frame in -20°C weather makes the difference very clear.

The warmth of the frame can be seen in the below models. Fiberglass is much less conducive to allowing cold temperatures to pass through the frame, thus helping to prevent condensation and loss of heat.
Climate Considerations
Installing ENERGY STAR qualified doors lowers energy bills and saves you money. With more efficient doors, you also use less energy, which reduces greenhouse gas emissions from power plants. Can you feel your carbon footprint getting smaller? .
