Spray foams offer greater airtightness and a more continuous, full-coverage seal when compared to rigid board and fibrous insulation. Open cell spray foam is a low-density insulation option that expands to fit hard-to-reach areas and provides efficient sealing of structural joints. While open-cell insulation R-values are slightly lower than closed-cell spray foam, open-cell spray foam offers greater lightweight flexibility, as well as soundproofing capabilities and greater expansion.
Open cell spray foam insulation is a soft foam insulation product, which is utilized primarily in southern U.S. states for any construction type.
Open cell spray foam insulation is a low-density, nonstructural insulation product. The tiny cells of the foam are not completely closed – they are broken. Air fills the open space inside the material, making the foam softer than closed cell foam. It has many great performance features including reduction of air infiltration, increased energy-efficiency, quieter environment and increased living comfort. Foam insulation can also be applied in difficult-to-reach areas that other insulation cannot.
Open cell spray foam insulation has a number of benefits, including air infiltration reduction, sound attenuation, and the ability to be applied in hard-to-reach areas.
GREAT FOR HARD-TO-REACH AREAS
Open cell spray foam insulation is a top insulation choice for contractors working on commercial and residential projects across the U.S. to fill difficult and hard-to-reach areas within construction. Whether it’s in tight spaces, cracks, or other difficult areas, open cell spray foam insulation will fill areas that traditional insulation products cannot.
REDUCES AIR INFILTRATION
Open cell spray foam insulation is well-known for its ability to reduce air infiltration in a variety of applications and types of construction. Since it effectively seals cracks and tight spaces, it helps to reduce the monthly and overall energy costs in a home or building.
EXCELLENT FOR SOUNDPROOFING
Open cell spray foam insulation also performs well for soundproofing needs in all construction types and applications. Whether you are soundproofing a whole building or a specific room, you can expect improved acoustic attenuation from open cell spray foam insulation.
Open cell spray foam is often used as an insulation technique for hard-to-reach spaces. This may include irregular gaps in insulation, as well as building joints and openings around ductwork or pipes. Open cell spray foam can also be sprayed from the inside against roof assemblies, including sheathing and roof decks.
R-VALUE
Open cell spray foam insulation has an R-value of 3.6 to 4.5 per inch. It’s important to know the recommended levels of insulation for your area, in order to prevent heat from transferring through. The higher the R-value, the thicker the blanket of spray foam will need to be.
