When it comes to insulating your home, closed-cell spray foam is a great option. It is generally accepted that 2 to 3 inches of this type of insulation is enough, but in the Pacific Northwest, experts recommend spraying 3 inches of closed-cell polyurethane spray foam insulation on the roof deck. This will help fix the dew point and prevent condensation. Closed-cell spray foam has an R-value of approximately R-6.5 per inch, while open-cell spray foam has an R-value of approximately R-3.7 per inch.
If you want to install spray foam on a pole wall and cost is not a factor, then closed-cell spray foam is the way to go. It is important to note that compressing an R19-R20 fiberglass block designed for cavities from 2 x 6 cavities to 4, a performance equal to R15-R16 would be obtained with that thickness. When installing closed-cell spray foam, it is important to make sure that the installer stops at a maximum depth of approximately 3 inches. This will help avoid having to trim the foam into a 2 × 4 inch wall. Additionally, it is important to install a sufficiently thick rigid foam layer on the outer face of the roof covering, followed by another layer of roof covering and a new cover.
This will help ensure that your home stays warm in winter and cool in summer, plus save on energy bills with our spray foam insulation. Spray foam insulation is an excellent way to save on energy costs and increase your profits, while demonstrating your social responsibility. There are more cost-effective energy improvements, such as rigid outer foam or mineral wool insulation, that can be used in combination with closed-cell spray foam for optimal results. Overall, closed-cell spray foam is an effective way to insulate your home and reduce energy costs. When installed correctly, it can provide your home with the necessary protection from the elements and help you save money in the long run.
