Handi-Fill® Wall Seal has been specifically designed with High Flow TechnologyTM to effectively fill blind wall cavities where there may be little to no existing insulation. Even better, it will not shrink or settle with time like other insulation materials. Handi-Fill provides a complete seal to stop air infiltration. The seal power to fill the cavity completely with just one fill point can be verified with the use of an infrared thermal imaging camera giving the customer complete confidence in the product. Handi-Fill 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.
