Wall Seal

HandiFoam® Wall Seal effectively fills blind wall cavities where there may be little to no existing insulation. In addition, it will not shrink or settle over time like other insulation materials, providing a complete seal to stop air infiltration, while providing an R-value of 3.4 per inch. Time and labor costs are cut significantly because High Flow Technology® gives Wall Seal the power to fill the cavity completely with just one fill point per cavity. This should be verified with the use of an infrared thermal imaging camera to give customers and contractors alike the confidence that cavities are full and a complete air seal has been reached.

HandiFoam® Wall Seal is GREENGUARD Gold Certified for low chemical emissions, providing one more level of comfort to homeowners that the product in their walls contribute to a healthier indoor environment.
