Kolbe introduces Ultra EP casement windows with triple pane glass for improved energy performance

Kolbe announces the addition of Ultra EP (Energy Performance) casement windows to its Ultra Series product family of energy-efficient, aluminum-clad wood windows.

The new Ultra EP windows feature triple pane glass to meet the ENERGY STAR® criteria for all Canadian climate zones, which went into effect Oct. 1, 2010.

Internationally, ENERGY STAR-qualified windows are tested and certified by an independent, accredited agency. Window products can qualify for ENERGY STAR based on their U-factor. U-factors for the four Canadian climate zones range from 0.21 to 0.32, expressed in metric units as 1.20-1.80.

Kolbe’s Ultra EP casement and awning windows come standard with 1-3/8-inch (2.54-cm) insulating glass and LoE coatings designed to achieve U-factors as low as 0.19 (approximately 1.00 in metric). Lower U-factor numbers indicate a slower transfer of heat from a warm area to a cold area. This is considered advantageous in colder climates where homeowners want to lower their heating bills by effectively and efficiently keeping the warm air inside.

Helping lower homeowners’ maintenance costs, Ultra EP wood windows’ exteriors are clad in durable aluminum. The aluminum is finished with a protective, fluoropolymer coating that carries up to a 30-year warranty, or with an optional, anodize that enhances the metallic appearance. On the interior, pine is the standard, but many wood species are available including those certified by the Forest Stewardship Council. A broad palette of paints or water-based stains can be specified, along with hardware and accessory choices, to match nearly any décor.

Contributing to smooth installation, Kolbe’s Ultra EP windows’ 3.25-inch (8.255-cm) jamb depth fits most standard applications. Kolbe’s craftsmanship is demonstrated by such construction details as sloped sills to direct water away from the structure and carefully coped corners on the sash. On the Ultra EP window, a 2.25-inch (5.715-cm) thick sash, multi-point keeper and engineered hinges accommodate the thicker, heavier triple pane glass, while ensuring nearly effortless operation for the homeowner.
