Spray Foam Insulation (SPF) is a fast and effective solution to maximize energy efficiency in your home or building. Unlike other options, spray foam insulation won’t ever fall out of place or lose it’s R-value once installed. Research conducted by the National Association of Home Builders (NAHB) has shown walls installed with closed-cell foam have a racking strength up to 300% greater than walls without it. Spray Foam Insulation is a great investment, paying for itself by saving on heat and cooling costs.
