Casement
The Gerkin 5300 casement and 5500 fixed
windows are designed with performance
in mind. The air infiltration on our casement
is often better than our competitors’ fixed
windows. These windows perform so well
in NFRC thermal tests that they have been
used in 5-Star Green Build projects, Net Zero
housing and numerous LEED certified projects.
