I would like to consider spray foam in my attic. What would that do to my ability to replace my roof? Also, what would need to be done with the roof vent s and other penetrations, soffets, etc.?
Spray foam insulation will not impact replacing your roof. Your roof can be replaced before or after the spray foam insulation is installed in your attic. When you do replace your roof, you will not have to spend money on ridge vents or off-ridge vents. When Summit Green Solutions installs spray foam, we close off the vents in the attic. We use landscape fabic to close off gable vents and porch areas. We seal off the soffit vents at the top plate of the exterior walls. We enclose the ridge vents with spray foam insulation. The end result is that we create an igloo cooler in your attic reducing the eliminating the extreme temperatures, improving the comfort of the home, improving energy efficiency and improving the indoor air quaility.
Should I use open cell or closed cell between my rafters? I live in Southeast Louisiana. Is it a personal preference or is there a recommended application?
Summit Green Solutions installs both open cell and closed cell spray foam insulation. Because we install both, we have the flexibility to chose the appropriate foam. We normally install open cell spray foam insulation in rafters because it allows mositure to dilute through the foam. If you have a roof leak, the leak will dilute through the foam and drip in your attic. If you are near the gulf coast, we may decide to install closed cell spray foam instead. Closed cell is more rigid and will add some structural support if your home is hit by a hurricane. For your case, it will be a personal preference – trading off the ability of the open cell foam to breath mositure with the structural integrity of the closed cell foam.
how do prices compare to regular blown insulation?
Regular blown insulation is only a insulator. It only controls conduction heat flow. It does not control convection heat flow. As an air barrier, spray foam insulation controls both conduction and convection heat flow. By controlling both, spray foam insulation greatly outperforms blown insulation. In addition, since spray foam insulation can be installed in the rafters of the attic, it will prevent the extreme temperatures from entering the attic. At the same time, it keeps the expensive good air from your hvac system from escaping through the vents in your attic. An attic with blown insulation can be between 120-150 degrees, while an attic with spray foam insulation will have temperatures in the 80s. Spray foam insulation will not deteriate over time. Traditional insulation will settle over time, loosing its air pockets and thus losing its R value. The investment in spray foam insulation will be between two to three times the cost of blown insulation.
Our home was built in 1991. Vinyl siding. One room in out house is about 10 to 15 degrees hotter than the rest of the house. There is a large picture window in the room, which we have completely blocked off with insulation. The room feels comfortable during the daytime, but gets very hot in the evening and stays like this until about late afternoon. I am beginning to think it is the attic space?
Most likely the room’s issue is related to insulation or the HVAC system. Is the home built on a slab? Is the HVAC ductwork located in the attic? How far away is this room located from the cenrtral HVAC system? I would welcome the opportunity to visit your home and provide a free evaluation.
Our home was built in 2003 (brick). One side of the house is noticeably cooler. Any thoughts on the cause? Do you do work in Burke County and what is the cost of an evaluation approximately 30 miles from Augusta?
One side of your home being cooler can result from improper insulation or improper HVAC ductwork or combination of the two.
