🔎 What Is Roof Foam Insulation?
Roof foam insulation—technically known as spray polyurethane foam (SPF)—is a liquid material sprayed into place that expands and hardens into an insulating layer. It's often used in lofts, on roof interiors, and occasionally on external roof surfaces.
There are two types:
- Closed cell spray foam: Denser and waterproof, but restricts airflow, leading to moisture problems.
- Open cell spray foam: More breathable and flexible but requires thicker application.
To understand the consequences of each, see our detailed article on closed cell spray foam problems in the UK.
