As goes the bonus room in this house, so goes many bonus rooms in homes across the southeast. Quite often, we hear homeowners who have this chronic problem complaining about their inability to enjoy their bonus room during the more oppressively hot months of June, July and August. Once the house is built, there seems to be no solution other than spending thousands to “beef up” the HVAC system to accommodate a heavier load on the A/C to keep the room cool. Most of the time, it is our experience to find inadequate insulation in the clipped ceiling area of the room. Additionally, there usually is no air channel between what insulation is there and the back side of the roof decking. This is a huge problem as intense heat is the number one enemy of composition shingles. They literally bake from the back side shortening their life and causing them to become brittle and worn out prematurely. Is there a solution for this short of tearing out all the drywall and adding insulation and air channel? You bet there is! At Caromark, we remove what existing insulation that is there and utilize a process of spraying a closed cell foam to a thickness of 5 inches offering an R-Value of 7 for every inch that is sprayed. One of many advantages to this system is that an R-Value of 35 can be reached in an area where the ceiling is framed with 2X6’s and still have enough room for air to flow up from the vented soffits to exhaust the hot air out the ridge vent. For conventional insulation products, you would have to tear out the drywall, pack down the 2X6 rafters with 2X4’s to create 10 inches of space to achieve an R-Value of 30 and install air channel while the ceiling is open. What a mess! As you can see, on this project, we were replacing the roof so we removed the plywood and batt insulation over the clipped ceiling and sprayed the foam in. We also blew an extra 3 inches of insulation over the flat ceiling area to insure proper R-Value there as well.
