Touch 'n Foam insulating sealants help control airflow in and out of homes by filling gaps in the home's exterior or "shell". Air sealing the home this way means you're better able to maintain a consistent temperature year round while enjoying lower utility bills. How do they work? Touch 'n Foam sealants expand to fill gaps and cracks, creating an effective barrier against the loss of heated (or cooled) air. This ensures you get the most out of standard insulation and HVAC systems. Touch 'n Foam sealants are also great for blocking moisture, dust, sound and insects – truly making your home a more comfortable place to live.
