Do you need to re-insulate your home? As a homeowner, you may not know much about insulation—but if you’ve been doing some research, you’ve probably seen or heard about the different materials. Foam insulation is used for both new construction and re-insulation projects, but there is more than one kind.
Installation Method & Material
Rigid foam insulation can be made of polystyrene, while spray foam is often made of polyurethane or polyisocyanurate. In terms of installation, spray foam is applied wet and expands into thick foam. Rigid foam, on the other hand, is available as a pre-made foam panel that can be cut to fit particular spaces.
Types of Projects
Rigid foam is typically used in new construction projects (rather than existing homes), in unfinished walls, including foundation walls. Spray foam is used for many retrofit (re-insulation) jobs and is ideal for hard-to-reach areas.
The R-values of rigid foam and spray foam insulation vary. Rigid board R-value ranges from R-3.8 to R-5.0 per inch. Polyurethane foam insulation can have R-values ranging from R-5.5 to R-6.5 per inch. Visit the U.S. Department of Energy to learn more.
Spray foam insulation can be installed in small crevices, cracks and gaps and can help with air sealing. Air leaks can undermine the performance of insulation, so making sure your home is properly sealed as well as insulated is the best thing to do.
Pros and Cons of Spray Foam
Spray foam insulation is a great choice for insulating hard-to-reach places, sealing cracks that air can escape through, and for achieving higher R-levels. However, it presents a higher upfront cost.
Pros and Cons of Rigid Foam
Rigid foam insulation is more affordable than spray foam insulation and works well in walls, but does not seal gaps as well as spray foam.
