Todol – PUR Fill WF Window Foam

Pur Fill WF window foam is a custom formulated one-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 fill void if needed.

Pur Fill WF has been tested and conforms to AAMA 812-04. The elastic merits provide flexibility during temperature swings. The foam cures to form a skin that acts as an air barrier as well as a moisture penetration prevention.
