When NOT to Use Spray Foam Insulation
Spray foam insulation is one of the greatest innovations around today as it provides more coverage and protection from Mother Nature and is catching on fast as one of the best options when insulating a home. While its flexibility allows it to conform to the space it insulates, there are a few limits you need to consider. Before your next insulation project, read this post to find out when you should NOT use this type of insulation.
Open-cell spray foam on your roof:
The potential for open-cell spray foam to rot a roof is still up for debate. As moisture from the inside can escape through this type of foam insulation and find the cold roof sheathing where it will sit and eventually rot the roof. Immaterial of what the climate is, you should not choose this type of insulation; instead, consider closed-cell spray foam.
For closed-cavity spaces:
Although the expansion level for spray and injection foam is the same, the rate of expansion does vary. Injection foam needs to expand slowly in order for it to reduce pressure. If you are installing insulation in closed spaces, for example, between studs in cavities of walls or brick, you should choose injection foam instead of spray foam.
If you suffer from skin, respiratory, or asthma:
Because spray foams contain highly reactive chemicals known as isocyanates, exposure can result in major breathing and skin problems. If you already suffer from pre-existing skin, respiratory, or asthma problems, you are at greater risk of exacerbating them when introducing the chemicals found in spray foam insulation into the atmosphere of your home.
