Polyurethane spray foam is a type of insulation that is widely used in both commercial and residential buildings. This type of foam is sprayed onto a surface and then quickly expands to form a thick, protective barrier. Polyurethane spray foam has a number of advantages over other types of insulation, including its high R-value, its ability to seal gaps and cracks, and its resistance to mold and moisture.

Advantages of Polyurethane Spray Foam Insulation

It has high R-value. One of the biggest advantages of polyurethane spray foam insulation is its high R-value. R-value is a measure of an insulation material’s ability to resist heat flow. The higher the R-value, the better the insulation. Polyurethane spray foam has an R-value of 3.8 to 4 per inch, which is much higher than the R-values of other common insulation materials like fiberglass (2.4 to 2.9 per inch) and cellulose (3.1 to 3.7 per inch). This means that polyurethane spray foam can help keep your home or office cooler in the summer and warmer in the winter, leading to reduced energy bills.

Seals Gaps and Cracks

Another advantage of polyurethane spray foam insulation is that it can seal gaps and cracks that other types of insulation cannot. This is because the foam expands as it dries, filling in any voids or openings in the surface it is applied to. Certain companies, such as Everest Systems, know that this can be particularly helpful in older homes and buildings where gaps and cracks are more common due to settling over time. By sealing these openings, polyurethane spray foam can improve the building’s energy efficiency by preventing heat loss or gain through these openings.

Resists Mold and Moisture

Finally, polyurethane spray foam insulation also has the advantage of being resistant to mold and moisture. This is due to the fact that the foam forms a tight seal on the surface it is applied to, preventing moisture from seeping in through cracks or openings. This can be beneficial in areas of high humidity or where there is a risk of flooding, as it can help prevent mold growth or water damage. 

Polyurethane spray foam insulation has many advantages over other types of insulation, including its high R-value, its ability to seal gaps and cracks, and its resistance to mold and moisture. If you are considering adding insulation to your home or office, consider using polyurethane spray foam for its many benefits.
