What is R-Value and Why do I care?
R Value is defined by the department of energy as the resistance to heat flow. Typically, the higher the R-Value, the better insulated you are. For example, to achieve what www.insulate.org recommends in attics, an R-Value of 49 for North Texas and 38 for South Texas, you would have to have approximately 15 1/2 inches of fiberglass batt insulation. With only 3½ inches of Sealection 500 spray foam, you get an R – value of 21. (Remember this is typically in what is called retrofit – homes that have already been constructed and have some other type of insulation already. That insulation is obviously not effective, which is why you need spray foam). We apply 5 ½ inches of foam in new construction, giving an R-Value of approximately 33. What we do? AACE will provide an individual custom evaluation of your home’s energy needs. We will address all your energy concerns and provide an estimate of the cost to install spray foam for you. We will schedule an installation time at your convenience,
