Re-insulating the walls is more labor intensive but 35% of energy heat gain or loss is through the walls, especially on the west side of your home where the sun heats the walls late into the day. To access the wall cavities between the studs, injection holes will be formed along the exterior walls so the technician can inject foam into the cavity. This injection process works on uninsulated walls as well as insulated walls. The foam will be injected and it will push aside the old insulation as it expands and cures. The foam does an excellent job of air sealing the walls and resisting heat.

Adding blown-in insulation to existing attics is the fastest method to reduce heat gain from the hot sun and has a faster return on energy bill payoff to help recoup the cost of retrofitting the attic. Attics lose about 25% of the home's conditioned air. In the hotter climate of Texas, that amount could be higher in the main months of the cooling season. It is obvious to the home owner if attic insulation needs to be added. You can look into the attic cavity and if you see the tops of the ceiling joist, you know the insulation has settled and is not performing as it should. The insulation in the attic will be fourteen plus inches deep, well above all of the ceiling joist, when installed correctly. Our professionals will make sure that the amount of insulation is correct throughout the entire attic. They will install paper makers at various places in the attic before blowing in the new insulation. These markers tell the technician when they have blown in enough insulation and it lets the home owner look to see that the jobs is complete. Over time, years, you will notice that the insulation will settle to some amount but the goal is to install enough insulation during the retrofit to last a life time.
