Pur Fill WF window foam is a custom formulated ne-component, minimal expanding, polyurethane foam sealant. Use around windows and doors to stop the passage of air and drafts.
Proper installation will assure no bowing or moving of the window. An inch of foam will have an R factor of 6. The goal for the window installer is to match the R factor of the window being installed. Do not overfill void. Place the foam as close to the exterior wall as possible and bridge the void with a 1/2-1 inch diameter bead. After this bead is cured, carefully add foam to completely fi ll void if needed.
