In this climate zone, a lot of builders like to use fiberglass insulation in the crawlspace. However, the problem with fiberglass insulation is when flood waters enter in, the water will soak into that insulation which will need to be removed and replaced.
The spray foam option Energy Assault provides is call 2 Pound Closed Cell foam. We’re able to spray this to the wood of your floor, sealing up your floors. The water, should it ever rise again, will not pass through the Closed Cell form. This same spray foam is used in Commercial applications. By sealing up the floors, not only does it help in case of flooding, it will help keep your floors warm during the winter helping to keep utility bills low.
