Rigid foam board is a firm insulation panel that packs a high insulating value into a thin layer. It is mainly used in new construction, and in our experience it is a great way to insulate homes and buildings for maximum energy efficiency. Stuff and Puff Insulation Experts installs rigid foam board for homeowners, builders and contractors across Miami-Dade.
Why Choose Rigid Foam Board
- High R-value per inch. Foam boards insulate more per inch than most fibrous insulation, which helps where space is tight.
- Continuous insulation. Installed as an unbroken layer, it reduces heat moving through studs and framing.
- Moisture resistant. Closed-cell foam boards resist moisture, a real advantage in Miami’s humidity.
- Versatile. Used on walls, roofs and foundations.
Types of Foam Board
The three common types are polyisocyanurate (polyiso), extruded polystyrene (XPS) and expanded polystyrene (EPS). Each has a different insulating value, moisture resistance and cost, and we will help you choose the right one for your project.
Frequently Asked Questions
Is rigid foam only for new construction?
It is most often used in new construction and major renovations, when walls, roofs or foundations are open.
Where is rigid foam board used?
Common spots include exterior walls, under roofing, and around foundations and slabs.
How does it compare to spray foam?
Both resist moisture and insulate well. Spray foam expands to seal irregular gaps; rigid board is ideal for flat, continuous surfaces. See spray foam insulation.
