Spray Foam Used as a Vapor Retarder in Iowa Homes
While most insulation types are prone to retain water and develop mold issues if there is a leak, this is not the case with spray foam insulation. Spray foam insulation can actually be used to keep moisture out of your home as well as to keep it insulated. By installing closed cell spray foam on the underside of your roof, you can keep your attic dry and warm all year long.
Overall, there are many great advantages to using spray foam insulation in the attic of your home in Iowa:
- Effectively Insulates Home
- Reduces Moisture Infiltration
- Eliminates Need for Ventilation
- Prevents Mold Growth
Most types of insulation soak in water if there are any leaks in the roof. This means that they become saturated and increase the likelihood of mold growing in your home. This is just one of the drawbacks to using traditional means of insulation instead of spray foam to insulate your roof and attic.
Why Use Spray Foam Insulation for Your Iowa Attic?
Because the spray foam binds so tightly to the bottom of the roof when it is applied, it prevents the materials that make up the roof from moving during changing temperature conditions. This reduces the chance that nails will pop or loosen, keeping opportunities for water entry from the roof to a minimum. The roof may still develop a leak if the construction was poor, but the moisture will not spread throughout the entire roof as it would with a more porous insulation material like fiberglass. Instead, the spray foam will prevent the moisture from spreading and damaging the entire roof and seeping through to the ceiling.
The effectiveness of spray foam at regulating the temperature in your home is just one of the reasons to choose it as the insulation material in your attic. Not only will spray foam insulation stop winter cold and summer heat from infiltrating your home, but it will also reduce moisture and leakage from the roof. Also, the ability of closed cell spray foam to trap moisture and air out of your home means that you no longer need ventilation in the attic. Ventilation is put in to carry moisture build up out of the fibrous insulation material to maximize thermal efficiency. Since spray foam insulation does not absorb moisture, no ventilation is needed.
