Illinois Attic Insulation
The correct amount of insulation in your attic will help reduce your energy bills. Attics are one of the easiest places in a Illinois house to insulate, especially if you'd like to “cap” your existing attic insulation (add insulation to what you already have).
Before insulating or deciding whether to add insulation to your Illinois attic, visit the U.S. Department of Energy’s website, to see if your existing insulation measures up. Chances are it doesn’t match-up to current government recommendations.
Our attic insulation specialists in Illinois measure your existing insulation during our Animal Entry inspections and let you know if you need to add more insulation to match the U.S. Department of Energy’s guidelines. Many insulation materials can be difficult to work with. Let the professionals at Critter Control do your insulation installation. We can also remove insulation that has been soiled/damaged and dispose of it for you.
Warning: If you think you have vermiculite insulation in your attic, there's a chance it could contain asbestos. Don't disturb it. Only insulation contractors certified to handle and remove asbestos should deal with vermiculite insulation.
Here are some insulation tips to consider before installing any type of insulation in your attic:
- Seal all attic-to-home air leaks. Most insulation does not stop airflow.
- Duct exhaust fans to the outside. Use a tightly constructed box to cover fan housing on attic side. Seal around the duct where it exits the box. Seal the perimeter of the box to the drywall on attic side.
- Cover openings—such as dropped ceilings, soffits, and bulkheads—into attic area with plywood and seal to the attic side of the ceiling.
- Seal around chimney and framing with a high-temperature caulk or furnace cement.
- At the tops of interior walls, use long-life caulk to seal the smaller gaps and holes. Use expanding foam or strips of rigid foam board insulation for the larger gaps.
- Install blocking (metal flashing) to maintain fire-safety clearance requirements (usually 3 inches) for heat-producing equipment found in an attic, such as flues, chimneys, exhaust fans, and light housings/fixtures unless the light fixtures are IC (insulation contact) rated. IC-rated lights are airtight and can be covered with insulation.
- Make sure insulation doesn't block soffit vents to allow for attic ventilation.
- Check the attic ceiling for water stains or marks. They indicate roof leaks or lack of ventilation. Make repairs before you insulate. Wet insulation is ineffective and can damage your home.
Also insulate and air-seal your attic access if it's located in a conditioned part of the house.
You'll want to properly insulate and air seal any knee walls—vertical walls with attic space directly behind them—in your home as well.
Finally, if you're constructing a new home or remodeling in Illinois, make sure any attic decking, which provides additional storage space or a platform for an HVAC unit or hot water tank, is raised above the ceiling joists to ensure proper insulation depth. The decking then should be installed securely to the top of the raised lumber after the insulation has been installed.
