Have windows been treated to reduce the risk?

Windows allow radiated heat to pass through and ignite combustible materials inside. The larger the pane of glass, the more vulnerable it is to fire.

Dual- or triple-pane thermal glass, and fire resistant shutters or drapes, help reduce the wildfire risk. You can also install noncombustible awnings to shield windows and use shatter-resistant glazing such as tempered or wire glass.
