Electrical boxes behind wall switches generally penetrate into the wall cavity, which make them potential sources of air leakage. These polyethelyne foam gaskets install behind electric switch plate covers to reduce drafts, saving both energy and money.
For double or triple gang boxes multiple gaskets can be overlapped and trimmed to fit.
