HandiFoam Extreme

HandiFoam® Extreme low-pressure, one-component, polyurethane foam sealant is a moisture cured, multi-purpose, polyurethane foam sealant formulated specifically for use in extreme temperatures and low humidity conditions. This will cure in outdoor temperatures as low as 0°F (-18°C). HandiFoam Extreme is designed for sealing small cracks and voids, preventing air and moisture infiltration.

HandiFoam Extreme is UL GREENGUARD Gold certified contributing to healthier indoor environments.

HandiFoam Extreme is available in a gun foam option and can be dispensed using a Handi-Tool® Dispensing Unit.
