Foam Board Insulation Installation Process
At Green Panther Insulation, our seasoned insulating installers use precise techniques to ensure effective rigid foam insulation installations tailored to your San Diego property.
Wood Framed Interior Walls (Surface Mount)
- Measure and Cut: Insulators carefully measure and cut Thermal Foam Boards using tools built specifically for rigid foam insulation to fit perfectly between wall studs.
- Secure Placement: The boards are then secured by the insulating installers using button cap nails and high-quality construction adhesive to create a strong, long lasting bond.
- Seal Joints: To make sure the insulation is reliable and withstands the harsh weather of San Diego, insulators apply foam board joint tape, sealing all joints and creating a continuous, airtight layer.
Wood Framed Interior Walls (In-Wall Installation)
- Layering for Depth: For deeper wall cavities, the insulators stack foam boards using construction adhesive to maximize thermal efficiency.
- Stud Fit Installation: The foam boards are installed snugly between studs by the insulating installers, ensuring a tight fit that minimizes heat loss.
Masonry/Cement Block Walls
- Furring Strip Method: Insulating installers mount 1” x 3” furring strips vertically using sturdy masonry nails to prepare the surface for insulation.
- Air Gap Creation: The foam boards are then attached to the furring strips, allowing an air gap for improved air circulation and better insulation performance.
With Green Panther Insulation’s skilled installers, you can count on a reliable and affordable installation that improves comfort and brings down the energy cost.
