Kolbe has introduced the Heritage Series XL Sterling double hung window measuring 48 inches wide by 120 inches tall. With a radius half circle and divided lites in the upper sash, this window provides historical style with modern aesthetics, efficiency and performance.
The XL Sterling presents Oak-stained Walnut on the interior and a Sapphire finish on the exterior. Heritage Series products offer an all-wood appearance, with exterior casings and nosings, several wood species, colors, finishes and prefinishes, divided lites and hardware. Antique Brass spoon locks and curved sash lift handles add further character to this window.
Energy-efficient, insulating LoE2-270 glass is standard on XL Sterling windows with several customization options to meet specific climate zone conditions and aesthetic preferences.
