Dangers to homeowner’s health

Although manufacturers claim that Spray foam insulation is “Green” it means “Environmentally Friendly,” but still has much danger to the health of homeowners or installers. Spray foam insulation is made up of chemical isocyanates that can cause severe skin and lung sensitization. Spray foam insulation also irritates the skin and mucous membranes in our bodies like the eyes.

Spray foam insulation can miss cracks in walls

During the application of spray foam, the foam expands rapidly. There are chances it doesn’t reach all of them properly while growing, and these gaps hurt the insulation’s performance. This can cause premature damage to the home walls and roof. Because the homeowner will not be aware of this damage, huge damage will occur before it can be noticeable.

Spray foam insulation sometimes causes water damage to the home 

If gaps are left behind after insulation, your home is at higher risk of water damage. Because air is trapped in these left pockets, water will be encouraged to enter. This mess would eventually lead to structural damages or its removal may cost more.

This shrinkage occurs mostly in homes located in geographic regions where extreme temperature differences occur.
