DIY Spray Foam Instulation

Spray  foam insulation or (SFI)  is a spray-applied plastic that forms  a continuous insulation and air sealing barrier on walls, roofs, around corners, and all other surfaces. The liquids react very quickly when mixed, expanding on contact to create foam that insulates, seals gaps, and can form moisture and vapor barriers. Spray foam insulation resists heat transfer extremely well, and it offers a highly effective solution in reducing unwanted air infiltration through cracks, seams, and joints. In other words spray foam insulation can knock your electric bill down significantly!

  1. I can see how this option would really help the efficiency of a home. We have a well insulated attic and our home inspector let us know what a help that would be for our heating bill. There are places that need to be insulated better in our basement and this will be a great option. How can you do this safely without getting intoxicated with the chemicals from the spray? Are there any that are not as toxic? I am assuming that it is toxic…is that right?

    1. Hello Lucy!

      Spray foam insulation sounds like it would be perfect for the job you described and you wont need that much if its just a touch up. i provided a link for coveralls to cover your skin and I would recommend a respirator if you want to be extra cautious.
