How is ZipFoam Installed?
There are two different ways to install ZipFoam. (1) spray it onto any open surface and studded wall (including metal) or (2) pour it into an existing wall cavity when renovating. A trained ZipFoam installer is required in either instance. With any open surface, ZipFoam can be sprayed on once electrical and plumbing services are in place. In seconds, Zipfoam expands to 100 times its initial liquid volume permanently adhering to the surfaces of the surrounding building materials and sealing all gaps. For retrofitting existing walls, a slower expanding formulation of ZipFoam is used. The material is simply injected into small holes drilled into plaster or gypsum walls, or from the outside of the wall. Since ZipFoam takes the path of least resistance, there’s no danger of bulging walls.
