Closed Cell Polyurethane Spray Foam (CC-SPF)
A structure's foundation, framing & insulation are the backbone of any build. Choose your materials, and the Contractors that install them, wisely. If the supplies or professional installation quality are not guaranteed, the project will always cost more."
NHI specializes in the installation of the highest quality Spray Polyurethane Foams (SPFs) on the market. Whether your project is 100 or 100,000 square feet, we have the equipment to meet the challenge. With the ability to spray both Closed Cell (CC) and Open Cell (OC) SPFs let us show you what's possible with these superior products.
There are numerous benefits to using CC-SPF and OC-SPF over traditional insulation. The most commonly referenced performance grade is the R-Value, or the resistance to heat flow. Closed Cell SPF has the highest R-value per inch on the market. With an average of R-7 per inch, Closed Cell SPF can provide code exceeding R-values in 2x4" constructed walls. This eliminates the necessity of costly 2x6" walls to achieve code with traditional insulation products.
The physical properties of Closed Cell SPF provide a vapor barrier, eliminating the necessary poly vapor barrier installed over traditional insulation. This saves additional labor and eliminates the risk of vapor intrusion by filling and sealing all voids to create a guaranteed air and vapor seal.
Additionally, the National Association of Home Builders (NAHB) testing has shown Closed Cell SPF increases the racking strength 330-400%. This provides crucial strength to a structure exposed to high wind shear generated by a tornado or straight line winds.
* Air barrier if the application thickness is appropriate
** Lifetime service if no vapor exposure
The Sound Transmission Class (STC) is the measure of this resistance to the passage of sound. Closed Cell SPF and Open Cell SPF can both be utilized to reduce acoustic conduction throughout a structure. The values shown above were procured from ASTM E 413-87. The higher the STC value the greater resistance to the transmission of sound. See example below:
