Apel PF370 Door and Window Foam is a one-component filling and installation foam that cures with ambient moisture and has a low expansion rate. It is specially formulated for the installation of door and window frames. With its lower expansion it fills all the necessary gaps without pulling, swelling or distorting your frames.

Features

• Excellent gap-filling and bonding capability.
• Cures with airborne moisture; ambient humidity accelerates curing.
• No expansion or shrinkage in volume after curing.
• The dispensed foam swells to at most twice its initial volume.
• Cured foam can be trimmed, cut and painted over.

Areas of Use

• Used in the installation of door and window frames, for filling cracks, as a filler in hollow structures, for insulating electrical and natural-gas installations, around hot-water pipes in boiler rooms, and for general-purpose gap filling.
