2 weeks ago - The most common types of materials used in making foam board include polystyrene, polyisocyanurate (polyiso), and polyurethane. Insulating concrete forms (ICFs) are basically forms for poured concrete walls, which remain as part of the wall assembly.
- How many types of foam insulation exist, and which is best for your project? Learn about spray foam, injection foam, pour foam, can foam, and foam board.
- There are three primary types of spray foam that can be used for insulation and other specific purposes: 3 lbs./cubic ft., closed-cell foam 2 lbs./cubic ft., closed-cell foam R-Values start at 5.7 per inch*
- From polyurethane variations to injection foam and rigid foam boards, understanding these products will arm you with the knowledge to make informed decisions for your insulation needs.
Rigid-foam insulation packs a lot of R-value into a thin package, but not all rigid foam insulation performs equally. Choose you insulation materials wisely by educating yourself on the unique performance characteristics of each rigid foam insulation type.
- Spray polyurethane foam (SPF) is a versatile insulation option that works well in various areas, from attic floors to exterior walls. It sticks to surfaces and expands to fill gaps, creating a strong barrier against air and moisture. Thats why SPF is a popular choice for both new builds and older homes being retrofitted.
