When properly installed, spray foam insulation can dramatically lower energy costs. However, this high-performance product isn’t without its potential complications. For example, improper installation of spray foam can cause moisture problems, resulting in mold, rot and other structural damage. This type of damage may result in expensive remediation costs that far exceed the cost savings realized from the spray foam itself.
Foam insulation seals the building envelope and reduces air leakage, which is the primary source of increased energy bills in a home or commercial structure. This is because the attic insulation expands to fill cracks and crevices, sealing air leaks that can allow outside air to enter the building and conditioned air to escape, forcing utility systems to work harder than necessary to compensate.
Why Spray Foam Insulation is Ideal for New Construction Projects
As the foam hardens, it creates a dense coating that can reinforce walls and other structures. It also can reduce the transmission of sound, making it a good choice for areas where noise is an issue. Some spray foam materials can have an unpleasant odor that some homeowners and builders find objectionable. This is caused by unreacted amine catalysts and has been described as smelling like fish, cat urine or fresh latex paint.
Spray foam is often used in basement rim joists, crawl spaces, overhangs and knee walls as well as for attics, cathedral ceilings and bonus rooms. It is a highly effective product that has the advantage of being easily installed in existing homes or in retrofit applications in new construction.
