Fiberglass - the Environmentally Friendly Choice

Fiberglass window frames are made primarily of the naturally occurring silica sand. There are little emissions produced in manufacturing and no ozone depleting chemicals are used. Fiberglass construction is among the least energy intensive of all window manufacturing processes. Efficient manufacturing, combined with long life expectancy and great insulating qualities make fiberglass a very green window choice. 

Fiberglass Windows - the Durable Choice

Fiberglass is highly impact resistant and won't chip like other window coatings. It won't rust, corrode, warp, blister or peel and it insulates against noise. Fiberglass window frames are highly impact, scratch and dent resistant and will retain their strength through years of adverse weather and temperature variations.  

Fiberglass is up to 9 times stronger than PVC and is even 3 times stronger than aluminum. That means your window frames will retain their shape and resist sagging. This durability will ensure smooth usability for the long run.
