Spray foam is great for insulating homes, and for creating an airtight seal to help with energy efficiency. It’s also a messy product that requires the skills of a professional to apply. Homeowners who try the DIY spray foam kits often end up with a mess of their own making, and they may miss all sorts of tight spots that a professional can easily get into. Choosing a professional to do the work is the best way to minimize the risks of mistakes and ensure a successful outcome for the project.
As a building material, spray foam is relatively toxic. It is sprayed on wood-framed walls, and when it sets up, it creates a strong and rigid barrier that prevents movement between the wood and the rest of the structure. It can be used for ceilings, walls, and other applications where an airtight insulation is required.
The Green Choice: Environmental Benefits of Spray Foam Insulation
There are two main types of spray polyurethane foam, open and closed cell. The chemistry of the products differ, and this determines their features and performance.
The blowing agents that are most commonly used in the products are hydrofluorocarbons (HFC). These have a high global warming potential, and there is a movement to transition away from them in favor of other materials. Some manufacturers have been able to reduce the percentage of HFCs in their spray foam, and some green builders have even started using products that are entirely free of HFCs.
It’s important to understand that spray foam is a toxic product, and homeowners must follow guidance on proper use to minimize exposure to the chemicals. This includes not occupying the house during the process and avoiding contact with the product for an appropriate period afterward.
