Windquest Series

Windquest series vinyl windows and patio doors, part of Kolbe & Kolbe’s K-Force impact-certified product line, are available in casement, awning, sliding and single-hung windows, and sliding doors. All products in the series have been tested according to Miami-Dade County HVHZ protocol, and have met large missile impact level D and wind zone 4 testing standards in excess of 140 mph, the manufacturer reports. Multi-chambered PVC extrusions create a thermal barrier for improved performance, while fusion-welded frames and sash corners prevent the infiltration of water and air, and provide greater structural integrity. The products are available with optional energy-efficient LoE glass with argon gas. They are available in white or beige, with numerous divided lite patterns from optional grilles-in-the-airspace. Trims, accessories, screens and a selection of handle and hardware styles are also available.
