Closed Cell Polyurethane Spray Foam (CC-SPF)
Foundation, framing & insulation are the backbone of any structure. If poorly installed, the project wasn't worth building. Choose these contractors wisely."
NHI specializes in the installation of the highest quality Spray Polyurethane Foam (SPF) on the market. Whether your project is 1,000 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) SPF let us show you what's possible with these superior products.
There are numerous benefits to using CC-SPF and OC-SPF over traditional fiberglass or cellulose insulation. The most commonly referenced is the R-Value, or the resistance to heat flow. CC-SPF has the highest R-value per inch within the insulation industry. With R-7 per inch, CC-SPF can provide code exceeding R-values in the 2"x4" constructed walls. This eliminates the necessity of costly 2"x6" walls required to achieve insulation code with fiberglass or cellulose products.
Exterior walls require a vapor barrier to halt the formation of condensation. With CC-SPF there is no need for a traditional sheet of poly with taped seams to create a vapor barrier. The physical properties of closed cells within CC-SPF are the vapor barrier. This saves additional labor and eliminates the risk of vapor intrusion by filling all voids to create a guaranteed seal. Additionally, the National Association of Home Builders (NAHB) testing has shown CC-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. CC-SPF and OC-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:
