Professional Spray Foam Removal in Henley on Thames

Spray foam insulation or spray polyurethane foam (SPF) is a liquid foam that’s sprayed into place before expanding and hardening into an insulating layer. There are two main types of spray foam:

Closed cell – this is a very good insulator but is a barrier to moisture and can reduce ventilation to the roof area.
Open cell – this is less dense, flexible and breathable. A thicker layer is needed to provide the same level of insulation.
