What Is So Great About Closed-Cell Polyurethane Insulation?
Closed-cell polyethylene foam is strong and resilient. It works great as insulation because it is vibration dampening, insulating, non-dusting, cost-effective, and impervious to mildew, mold, bacteria and rot. Closed-cell foam insulation can last for upwards of 80 years if you take care of your home and will actually improve the stability and sturdiness of the structure. This foam insulation is non-flammable and prevents moisture and critters from getting into your home.
