In the past several homes, we have been using a fairly new form of insulation; open cell foam insulation. Open cell spray foam is not new to the building industry, but it has not been widely used until recently. We have partnered with a local company, Energy Guard Foam Insulators, to install this type of insulation in our homes. I have been watching the open cell spray foam industry for the past 3-4 years, paying close attention to the construction requirements, field testing, and the energy savings. After careful review we have chosen to use SEALACTION500 by Demilec. We feel this is the best product, and the product that fits our clients needs the most. When insulating with open cell spray foam, you insulate the walls traditionally, but in the attic you insulate the roof deck rather then the joist area. This creates an envelope that allows the attic temperature to be with in a few degrees of the living area. By having a cooler attic, it allows the air conditioning system to operate more efficiently. The open cell foam insulation also allows us to use a smaller tonnage A/C unit, this also helps to keep the utility costs lower. This makes for a wonderful product.
