The Pitfalls of Spray Foam Insulation

Spray foam insulation has become a popular addition to home renovation projects, and even new construction. It is touted as a quick, energy efficient solution to making homes more comfortable and environmentally friendly. Unfortunately, it is not without its pitfalls.

One of the main issues with spray foam insulation is that it is very airtight. This can be a good thing, but it is also problematic for many homeowners. This is because it makes it very difficult for house occupants to ventilate properly, and can lead to health issues. Another issue with spray foam is that it can shrink or separate over time. This can lead to gaps, which are a problem for both the efficiency and resale value of the home.

Another major concern with spray foam is that it often contains volatile organic compounds. These are chemical solvents that can irritate the skin, eyes, and lungs. They are also known to be carcinogenic and cause other health problems. These chemicals include isocyanate, benzene, formaldehyde and chlorine compounds. It is important to only use a spray foam with low VOC content.

In conclusion, it is important to always use a professional installer for any project involving spray foam. Be sure to get references, ask about training and how aware they are of the dangers of working with this product. If they dismiss your concerns or tell you it is perfectly safe, then they are not worth hiring. Also, only work with a company that uses the low-GWP blowing agents. (These are currently HFOs) These have a much lower global warming potential than the former HFC blowing agents. pitched roof insulation
