Spray Foam Insulation

Spray foam insulation is one of the most energy saving and environmentally friendly insulation technologies available. Its R value, a measurement of its insulating qualities exceeds any other traditional insulation. Closed cell foam insulation has an R-value of 6.9 per inch which offers a bit barrier at 2 inches that can add up to 300% structural strength to your home. Spray foam is a monolithic application that seals and blocks out air infiltration keeping dust and other outside contaminants out, making your indoor air quality up to 40% cleaner than outdoor air with a proper filtration system.

Injection Foam Insulation

Injection foam is a great way to retrofit an older home for greater energy efficiency. Because the process involves an expanding liquid foam, there is no need to tear down walls, or even remove old insulation. A home retrofitted with injection foam will immediately become more energy efficient, and stay that way since injection foam will not deteriorate or settle over the life of your home.
