It seems that the weather is getting more extreme these days, with earthquakes, hurricanes, tornadoes and flooding causing extensive damage to homes and buildings. Building design and structural integrity will help a building withstand stress, in all kinds of weather events. Spray foam insulation can play a role in building design and protection. It’s low water absorption rate, tensile strength and super high adhesion force all help protect buildings during periods of damaging weather.
The water resistant property of spray foam insulation can be helpful in flood-prone areas near coastal areas and rivers. Not only will spray foam not need to be replaced, but it will lead to a faster clean-up time and enable you to re-occupy your home sooner. It helps when flood-damaged spaces just need to be dried out, not rebuilt from the ground up.
The adhesive properties of spray foam also add strength to roofs and walls during periods of damaging winds. In a heavy storm involving shingle damage, spray foam on the interior roof area can act as a “back up” barrier to water damage. In periods of heavy wind, spray foam increases the durability of wall structures, helping to minimize damage.
The Federal Emergency Management Agency, also known as FEMA, has classified spray foam insulation as highly resistant to floodwater damage and easily to clean from post-storm pollutants. The sealing characteristics of foam helps prevent water damage. The connective properties of foam add to wall and roof strength in periods of high winds.
