Why Fiberglass?

Santoprene™ Weatherseals
Santoprene™ rubber weatherseals make our windows airtight and watertight across a range of extreme temperatures
Maximum Energy Efficiency
Pultruded Fiberglass is our material of choice for windows, meaning they have a much lower thermal conductivity than other materials. This combined with our insulated frames and sashes, results in some of the most energy efficient windows in the world.
Strength, Durability, & Stability
Pultruded Fiberglass is the strongest of all window materials. Fiberglass is eight times stronger than PVC, over three times stronger than wood composites, and 20% stronger than aluminum.
Our windows use thick-wall vinyl that is multi-chambered with fusion welded joints. Durable, sturdy and air and watertight sealing means windows won’t bend, warp, discolour, corrode, rust, fade or deteriorate under any conditions.
