Glastra Frame System

The Kolbe Forgent GLASTRA Window

What is the Kolbe Glastra Forgent window? Opal Exteriors demonstrates.

We install Kolbe Forgent Series windows made of Glastra, a proprietary blend of copped, short-strand fiberglass, interwoven with UV stable polymers (think of it as a weldable, stronger type of fiberglass). Kolbe has been around since the 1940s and remains an industry leader in residential windows.

Kolbe continuously innovates their products to combine old-world craftsmanship with new-age technology. Forgent frame corners are welded (stronger than corner key joints). These frame corners:

Are extremely structural and water-tight. At no point will it ever slip, open, or gap with installation or transportation
Require at least 400 pounds of pressure to break. Typical fiberglass is 100-150

Acrylic exterior

Acrylic film on the exterior means that no painting is necessary. Traditional fiberglass paint scratches easily. Kolbe uses acrylic that is more durable to abrasions than standard fiberglass, and has a substantially better lifetime fade ratio.
