Optimum's Fire Rated Double and Single Hung Steel Windows

Here at The Window Man we're pleased to carry Optimum's Series SC7650 fire-rated double and single hung steel windows.

These steel double and single hung windows have been proven to withstand temperatures in excess of 1650 degrees (900 degrees C) in laboratory tests. Even after 45 minutes of fire exposure all individual muntins, mullions, jamb members and sash components remained in position. Each window features two fusible link components made of slow melting alloy. When exposed to temperatures of 165 degrees or more, the links melt and automatically seal the window shut, which prevents the spread of smoke and fire to adjacent buildings.

Stop by any of our three Northern Virginia showrooms to see if the Series SC7650 windows are right for your renovation or new construction project.
