Fiberglass Advantages

Low Thermal Conductivity / Energy Efficient

Pultruded Fiberglass profile insulates better than any of the traditional window and door materials. The thermal conductibility ratio is 500x less than aluminum. Insulating the frame and sash components reduces the conductivity even further, allowing for the creation of some of the most energy efficient window and door systems.

Low Maintenance

Fiberglass is the most stable material in virtually unlimited colors and an interior wood veneers. The maintenance-free frames stay true to form due to strength of materials. No need for sanding, painting, or staining.

Environmentally Friendly

Fiberglass Strings are made mostly from silica sand (sustainable natural resource), the lineal manufacture process consume the least embodied energy when compared to other common window frame materials such as Aluminum and PVC.

A440 Approva & NAFS PG90 Standard

Fiberglass Structural Integrity

High Dimensional Stability

The coefficient of expansion/contraction of pultruded fiberglass material is extremely low and almost identical to that of float glass. The low thermal expansion rate means tighter seals against weather and longer lasting. Vinyl expands at over 7x this rate.

Fiberglass Structual Integrity

Fiberglass is used to replace steel in many applications due to its high strength to weight ratio.

Fiberglass is 8x stronger than vinyl

3.5x stronger than wood/vinyl composite

2x stronger than aluminum
