Our fixed windows complement our casements as a stand-alone fixed window or they can be used to mull fixed and specialty shapes together in order to create custom configurations.
The 5500 fixed windows are designed with performance in mind. These windows perform so well in NFRC thermal tests that they have been used in 5-Star Green Build projects, Net Zero housing, and in numerous LEED certified projects.
Gerkin's 58F series offers a great alternative to storefront systems. Gerkin has designed this window to look like storefront but offer superior thermal performance, water resistance, and air infiltration.
