Sill Seal

Sill seal is ribbed polyethylene foam used to seal the gap between the sill plate and the foundation. Lightweight and resilient, it is easy to cut to length and installs without tools. The ribs effectively seal out air currents, moisture and insects, leaving you worry free to enjoy your home.

Sill seal is available in 3/16” by 50 foot long rolls in widths of 3 ½”, 5 ½” and 7 ½”. Custom cut widths are available upon request. Sill seal is packed in boxes suitable for UPS shipping.
