Turn Your Home into an Energy Efficient Fortress by Adding Expanding Foam Insulation

Using expanding foam insulation requires a methodical approach by adhering to a few key principles and safety standards. When working with spray foam, ensure you use safety equipment such as protective clothing, eye wear, and a certified and adequate respirator face mask. It is also essential to mask off all areas, especially electrical equipment and cover windows with plastic sheeting. Working with expanding foam insulation can cause itching and redness of the skin, which can be limited by showering immediately upon completion of the spraying of insulation.

To begin spraying the foam, position the applicator 20 inches from the area being covered, then start with a conservative 1 inch bead of insulation around the wall’s 2x4s. Move the applicator across the intended area in an up and down, or side to side motion; adhering to the manufacturer’s instructions and using conservative applications to ensure adequate coverage. Allow for the foam to dry before making subsequent applications. The foam should be trimmed level to the wall using a carpet razor knife and to ensure it does not protrude.

When complete, inspect the area for complete coverage, being sure to fill in any voids. When working with reducing foam insulation never exceed the adequate coverage and try not to use more product than needed. Once coverage is complete, clean up the area as best as possible and make it flush fitting. Aim to have a wall of insulation that looks good and will accommodate applications of other building materials.

To summarize, use the best safety practices when applying expanding foam insulation, following the manufacturer’s instructions to complete each section of the process. Start with a conservative 1 inch bead of insulation, moving the applicator across the area at an even pace to ensure adequate coverage and then allow the foam to dry before making further applications. Trim excess foam avoiding any protrusions, then clean up the area. Inspect the area for complete coverage, filling any gaps as needed and the job should be complete.
