Posted on February 4th, 2019

Kolbe-2019-IBS-Forgent-AE400web.jpgDuring the National Association of Home Builders International Builders' Show (NAHB IBS) in booth #C2519, Kolbe Windows & Doors will highlight the expanded offering of its Forgent® Series window and door products.

Kolbe's innovative Forgent Series is a high-performance product line constructed of Glastra® – a hybrid of fiberglass and UV-stable polymer formulated for strength and resilience. Multi-chambered Glastra extrusions in an advanced ladder design add strength and promote energy efficiency. An integral nailing fin, and welded sash and frame provide rigidity, keeping units square, and preventing air and water from entering the joint.

Kolbe-2019-IBS-Forgent-AE417web.jpgForgent Series casements, awnings, double hungs and sliding windows are engineered with Glastra on the exterior, with either wood or Glastra on the interior. Complementary specialty windows, sliding patio doors and swinging patio doors also are available with the same aesthetic options.

"The Forgent Series is the perfect solution for projects with short lead times," says Mark Harger, Forgent's general manager. "Designed for strength, performance and ease-of-installation, Forgent Series windows are simple, convenient and easy to install."

Builders can choose from three convenient installation options – integral nailing fin, installation clips and screw through frame – based on which will be fastest and easiest for each project.

Kolbe has added a new construction frame design for Forgent Series double hung and sliding windows. Additional interior finishes offer a choice of 11 different stain colors, plus black and white paint for Glastra/wood units. For All Glastra units, a midnight or bronze interior is available.

Kolbe-2019-IBS-Forgent-AE823web.jpg"Through ongoing research of new materials and development of advanced design, Kolbe continues to bring the best products to market," says Jeff De Lonay, president of Kolbe Windows & Doors. "Proprietary material and thoughtful design elevate Forgent Series windows and doors above other vinyl or fiberglass products."

This unit features energy-efficient insulating glass with 7/8-inch performance divided lites on the top sash, matte black hardware and a BetterVue® mesh screen.
