Foam Injections

Polyurethane (PU) foam is commonly used between the back of a bath product and it’s base to provide mechanical support and sound and heat insulation. If the bath tub or shower base does not have PU foam, and exhibits poor strength, it can be injected into the cavity to improve its performance. PU foam is also used in spa construction for the same purposes. Low-density PU is used for insulation, and high-density is used for support.
