The Kolbe Forgent GLASTRA Window

Opal Enterprises installs Kolbe Forgent Series windows made of Glastra,  a proprietary blend of copped, short-strand Fiberglass, interwoven with UV stable polymers (think of it as weldable, stronger type of fiberglass). Kolbe has been around since the 1940s and continues to be an industry leader in 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 film on the exterior means that no painting is necessary!

  • Traditional fiberglass paint scratches easily, Kolbe uses an acrylic that is more durable to abrasions than standard fiberglass and has a substantially better lifetime fade ratio.

Furthermore, Forgent Series windows:

  • Come in all the styles popular in Naperville, Des Plaines, and other Chicagoland suburbs, including traditional double-hung for timeless appeal, casement for wide-open views, sliding for effortless operation, and awning for ample ventilation even when it’s raining.
  • Are available with Glastra or wood interior options
  • Deliver energy-efficient and impact-resistant performance to meet local climate demands
  • Feature extra strength due to an advanced ladder design with multiple chambers
  • Feature a wide selection of exterior and interior finishes for curb appeal
  • Bear the ENERGY STAR® label as a mark of thermal efficiency that can ease your HVAC system’s workload and reduce your monthly energy bills.
