When cavities are missed by installers when using a spray foam insulation product, then this creates the potential for a higher risk of water damage throughout the life of the structure. When air gets into the various pockets of the home, especially ones that are in the attic, then the pressure change can encourage water to seep in through building imperfections. This process can cause premature damage to the walls and roof of the structure. Because it is unknown to the homeowner if a lack of coverage occurred until the damage is noticeable, it can be challenging for them to recoup their losses outside of their insurance policy.
Spray foam insulation is becoming a preferred product because it is fast and easy to install at a reasonable price. As this product ages, it is possible for the insulation to start shrinking and thereby reducing the insulative qualities it provides. Homes that are located in geographic regions where extreme temperature differences occur typically have the highest risk of experiencing this outcome. When it begins to pull away from the framing, the other disadvantages mentioned above this one can occur.
Spray foam insulation does create health effects and risks to consider.
Many of the risks that are associated with spray foam insulation involve the installer only. Some of the primary ingredients in this product are called “isocyanates.” These chemical compounds can irritate the lungs, eyes, and stomach when coming into contact with them. If your skin comes into contact with the foam, then some people can develop swelling, skin rashes, and inflammation. You must wear a respirator, goggles, and gloves when working with this product. Long-term exposure can trigger asthma attacks and chemical bronchitis.
