PVC PIPE PENETRATIONS
Unless you live in a frontier cabin without running water, there will be many pipe penetrations into and out of your home, as well as to and from the living space. Each and every one should be sealed with GREAT STUFF™ Gaps & Cracks. Fortunately, it's easy. Just follow the pipes (whether they're metal or PVC) and everywhere there is a wall or floor penetration, fill and seal the gaps with GREAT STUFF™. (GREAT STUFF™ Fireblock should be used for penetrations between floors.)
