Our Attic Insulation Process
All of our expert crews follow these essential steps to ensure proper attic insulation installation:
- Attic Air Seal: Seal holes and penetrations formed by, but not limited to, plumbing, electrical fixtures, wall joints, and any other accessible voids with foam and caulk.
- Cover openings (such as dropped ceilings, soffits and bulkheads) into the attic area with a rigid material 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 and expanding foam or strips of rigid foam board insulation for the larger gaps.
- Install metal flashing, or like material, to maintain fire-safety clearance requirements (usually 3 inches) for heat-producing equipment found in an attic, such as flues, chimneys and exhaust fans. We also include light housings/fixtures unless the 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 proper attic ventilation.
- Install baffles to allow for proper soffit ventilation
- Check the attic ceiling for water stains or marks, which indicate roof leaks or lack of ventilation.
- Insulate and air seal your attic access if it’s located in a conditioned part of the house.
- Properly insulate and air seal any knee walls or vertical walls with attic space directly behind them, including any skylights.
- Ventilate your current bath fan with proper pipe and termination kits out of the attic space.
