Consider this: If you took all the gaps and cracks around window and door frames, electrical outlets, plumbing lines, under the siding, in the basement, and in many other places in your home, they'd add up to a space the size of a standard window. So essentially, you're heating and cooling your house year-round with a window open.
There are six formulations of GREAT STUFF™ Sealants to help you close these gaps and cracks: Gaps & Cracks, Big Gap Filler, Window & Door, Fireblock, Pond & Stone and Pestblock.
GREAT STUFF Gaps & Cracks expands to fill, seal and insulate gaps up to 1 inch inside or outside your home. It forms a durable, airtight, and water-resistant bond that reduces drafts, making your home more comfortable and less expensive to heat.
