Kolbe’s Old World Classic triple-hung windows expand the vertical space for greater views, increased daylight and natural airflow while offering high performance and design flexibility. The windows’ precise architectural details are customized to match traditional and historic buildings. The units, which feature a chain and pulley system to meet strict historic standards, may be specified in numerous wood species, finish options and exterior wood trim choices. Curved glass or wood exterior decorative accessories, such as pediment heads, keystones, rosettes and corner blocks, complete the aesthetic.
