Homes that are built before the 70’s will most likely have no insulation inside the wall cavities. Exterior walls account for 20% to 30% of the heat loss through a home as a whole. Having insulation prevents radiant heat from entering the living area during the summer. Walls facing the sun are the most affected and create the utmost radiant heat. There is no need to install insulation in the interior wall unless you want to reduce the sound. For example: a shared wall between the bathroom and the bedroom can be injected with insulation to reduce the sound of the toilet flushing. Whatever the case may be, please give us a call and we will work with you to come up with a solution.
Most people with an older home are not aware that their walls have no insulation. Insulating your walls will greatly reduce the heat loss in the winter and help reduce radiant heat from entering your home in the summer.
Our professional team can inject blown in fiberglass or cellulose insulation inside the wall cavities. The work will consist of drilling a set of 2 inch holes every 16 inches or 24 inches across the wall which can be done inside or outside the house.
One hole will be above the fire block and one below. The holes are then plugged with a Styrofoam plug. We charge by square foot and will deduct the doors, windows, fireplace and any other areas that we cannot insulate. Please see the illustration to the right:
For new construction or remodeling where drywall has not been installed, we can install fiberglass batts or Roxul for a better soundproof. Once the insulation has been installed, the homeowners can then install the drywall. Please give us a call for a free assessment.
