Frost King Ac43h Air Conditioner Foam Weather Seal, 2-1/4 X 2-1/4 X 42 In.

Window air conditioners can leak cool air around the edges and allow heat transfer, reducing efficiency and increasing energy costs. Frost King AC43H Air Conditioner Foam Weather Seal fills gaps around your air conditioner unit to help it cool more efficiently in summer while preventing heat loss in winter. This open cell polyurethane foam strip compresses to fit irregular gaps and stays in place through seasonal temperature changes.

The high compressibility of the foam allows it to conform to gaps while maintaining structural integrity, and its design helps reduce vibrations from the running unit. This weather seal is made of highly compressible open cell polyurethane foam that adapts to the space around your air conditioner.
