DRAFT BLOCKING AND SEALING PRODUCTS Foam switch, electrical outlet gaskets and sealers really help to seal wall plates and electrical sockets. Electrical outlet and switch boxes generally penetrate into the wall cavity, which make them potential sources of air leakage and thermal loss. This results in a heating and cooling loss by as much as 20%. Don't get messy with caulks and sticky spray foams. Made of UL listed foam, our socket sealers are pre–stamped to fit precisely. Installed easily behind the faceplate, they are completely invisible. When installed, they work to reduce drafts while helping to keep heat in your home during the winter, and the cooling in your home during the summer by insulating and air sealing. Because of our awesome prices, you can now buy in bulk and save tons compared to retail packs found in hardware stores. Our electrical outlet sealers/gaskets are top quality in the industry and will provide a tight seal while insulating at the same time. Add even more protection to socket sealers by installing child safety outlet plugs. Since electrical receptacles are also a leak point, you can add a greater level of performance to the safety outlet plugs by using the scrap outlet punch-outs (click here for demonstration). For double or triple gang boxes, simply lay multiple sealers side-by-side and trim to fit with a pair of scissors.
