Tiger Foam Slow rise formula is engineered to spray into existing wall cavities. This formula is a low pressure, low expansion formula that is designed not to blow the drywall off as long as it is attached using standard building practices. This makes it an excellent choice for older and historic homes that may have no insulation/air sealant in the wall cavity. Works well behind plaster and lathe walls or any cavity fill application.
