How does foam sealant compare to other types of insulation?
Unlike caulking materials and other sealants that are solid, heavy and non-insulating, foam sealants expand to form an outer skin that contains closed air cells that provide an effective barrier against energy loss. DAP Foam forms a permanent seal that will not shrink or pull away from the material it has bonded to, making foam the best sealant available against air and moisture infiltration.

MaxFill and Home Seal formulas may also be used indoors or outdoors. These foams should be painted when used outside in order to prevent discoloration and break down from UV exposure. DAP Foam can be painted in about one hour after dispensing. Touch 'n Foam No Warp, Fire Break and Mouse Shield should be used indoors only.
