Two triple-hung window lines from Kolbe, Old World Classic and Ultra Series Sterling, offer large amounts of vertical glass. This allows for expansive, unobstructed views, increased daylight, natural airflow, and design flexibility. The Old World Classic’s chain-and-pulley system provides a vintage feel and meets many historical building standards. It comes with decorative accessories such as pediment heads, keystones, rosettes, and corner blocks. The Ultra Series Sterling has a wood interior clad with aluminum and operates smoothly with spring-loaded block-and-tackle balances. The windows include insulating glass with low-E coatings, and laminated glass is optional for safety, security, sound control, and UV control.
