GREAT STUFF™ or GREAT STUFF PRO™ Gaps & Cracks and GREAT STUFF™ or GREAT STUFF PRO™ Pestblock can be used for sealing pipe penetrations through walls. GREAT STUFF PRO™ Gaps & Cracks is also fireblock rated.; GREAT STUFF™ and GREAT STUFF PRO™ Pestblock are specially formulated to block insects and pests from entering the home by sealing gaps and cracks where they commonly enter.

Every home is a sprawling network of pipes. That means unwanted air (and pests) can run from the basement, to the kitchen, through dryer vents and up into the attic. And don’t forget the plumbing pipes hiding in bathroom cabinets and utility sinks. A recent study showed that sealing pipe penetrations under the sink can save homeowners an average of $45 a year on energy bills. ¹

¹In this study conducted by Dow and D.R. Nelson & Associates, air loss was measured using blower door tests. Potential energy savings were estimated using REM Home Energy Analysis Software. Results vary based on construction, style, year built and other unique home characteristics. Participating homeowners were current employees of Dow.
