Open cell spray foam is full of cells that aren't completely encapsulated. It is cheaper and not as rigid as closed cell foam and makes the foam quality a softer material. It is composed of many air bubbles held within a polyurethane matrix, applied through a spray nozzle to an open wall cavity and quickly expands to fill the space. Unlike closed cell, you can't get open cell foam wet as it isn’t as water resistant as closed-cell foam. It does not block vapor but instead allows it to pass through the foam matrix.
- Effective in hot climates where loads are primarily cooling.
- Great use for soundproofing/ reducing sound.
- Adheres well to steel studs and other natural materials such as cement board, wood, celing.
- Totally filling the entire cavity in easy and quick process without the need of cutting fitting it around.
- Air sealing benefit with only 4 inches of thickness, open cell can prevent the air from going through.
- Crawl spaces
- Hard to insulate areas
- Attic conversions
- Under floors
- Timber Frame
- Sound reduction
Closed cell foam is considered a “closed” cell due to its high R-value compared to other insulations. The R-value is the material’s capacity to insulate and resist heat flow. The higher the R-value the greater the insulating effectiveness. Closed cell foam is essentially incompressible once fully form and cured. This material can insulate buildings and appliances. Due to its high resistance, closed-cell spray foams resist water penetration and moisture build-up, it prevents mold growth, and used in keeping regulated temperatures and can even strengthen building structure.
- Insulate the area effectively better than any other insulation.
- Energy Saver and Eco-friendly - closed spray foam reduce energy consumption for up to 40-60% average.
- Creates powerful airtight seal.
- Moisture barrier and prevents molds growth.
- Strengthen building structure.
- Pole barns
- Garages and sheds
- Metal Buildings
- Storage Tanks and Containers
