This article first appeared in the October 2019 issue of Pro Builder.

Part of the company’s Ultra Series line that mimics traditional wood windows and doors, the Sterling double-hung unit from Kolbe Windows & Doors features interior wood covers that conceal the jamb liners and balances to create an all-wood appearance. Low-E glazing results in U-values as low as 0.21, and aluminum cladding delivers low maintenance. Customers may choose from 14 interior wood species and a range of exterior colors.
