Hurricane season is in full swing, and households all throughout the United States might be questioning whether or not this will be the year that a massive natural disaster strikes their city or community, particularly if it’s situated close to the coast.
Spray foam insulation has long been recognized, by people in the marketplace, for its capacity to help restrict moisture-laden air from entering structures where it is installed, but the moisture in the air when a hurricane is battering at the windows is a totally different story. This doesn’t even take into consideration the significant potential for water damage that may arise.
Almost every year, the cost of damages which arise due to hurricanes or major tropical storms making landfall in the United States total in the billions of dollar. Heavy rainfall, storm surges, and coastal flooding can all contribute to the damage of houses as well as other structures. The nation can pray that we will never again experience a catastrophe as epic as Hurricane Katrina, and the chaos it inflicted on the crumbling infrastructure of Louisiana, but readiness is the key.
Consider insulation. With conventional insulation products, their primary purpose is to insulate your house from the heat as well as the cold weather that seasonal weather brings. Traditional insulation’s main function is not to safeguard against water damage, so if and when this happens, it provides virtually no obstacle to moisture entering the house in any kind of way. Traditional insulation materials often have the potential to absorb moisture entering the home, and are unable to dry out quick enough to withstand damage. They quickly become saturated whenever excess moisture appears, such as during flooding, which can result in mold growth. This not only minimizes the effectiveness of your insulation’s R-value, any insulation saturated in contaminated water will ultimately need to be disposed of and the area, re-insulated. Certainly not particularly ideal, when you reside in a hurricane-prone area of the nation.
Alternatively, spray foam insulation has the capacity to better manage moisture movement. And, since spray foam expands within a few seconds of installation, small gaps and cracks can be filled effectively, establishing an air seal on your home.
It’s important to keep in mind that not just any type of spray foam insulation that will help, when it relates to the kinds of situations your home might withstand during a hurricane. The best type of spray foam insulation you can install in your house is closed cell spray foam, like the type offers.
There are several factors which make closed cell spray foam insulation distinct from various other kinds of spray foam. Compared to the spongey, flexible structure of open cell spray foam, whenever closed cell spray foam insulation is sprayed in, it promptly becomes rigid. This rigidity can be a crucial element in structures located in a hurricane-prone zone. This is due to the insulation’s ability to provide structural integrity to roof structures covering unvented attics, which can help prevent roof blow off, something which is all too common when the strong winds of a hurricane exist and wind uplift is an issue.
Why, exactly, is wind uplift and roof blow off a concern? As soon as the roof of a house is impacted off, even partially, water from the hurricane can get into the structure easily, resulting in massive amounts of destruction. Water damage goes rampant, and the house becomes uninhabitable quite rapidly. And while damage may not be completely prevented, simply because the roof remains intact with spray foam insulation, it can at least be diminished.
Additionally, closed cell spray foam has exceedingly low water absorption. Did you know that the Federal Emergency Management Agency (FEMA) has ranked closed cell spray foam insulation as a highly acceptable flood-resistant building material? That means that your attic and roof can better sustain the wind-blown water that often pummels homes during a hurricane, but it also means that other key areas of flooding can be better protected.
When it relates to your home’s basement or crawlspace, having insulation which rejects bulk water, the way Icynene closed cell spray foam does, could go a long way in helping to reduce significant damage that hurricanes often create. In order for FEMA to consider a product to be flood-resistant, it must have the ability to endure direct exposure to floodwater for a prolonged period (72 hours) of time.
