Despite the fact that installing insulation in an attic is a simple job, it is not so easy to choose the right product. When it comes to adding insulation to the attic, the most convenient solution is installing fiberglass batts. However, this is not the ideal choice because fiberglass batts are very poor insulators. While there are several other solutions available, none of them are as efficient as spray foam insulation. The fact is that this product meant to reduce heat loss actually outperforms others. Therefore, it is highly efficient and it will save you money in the long run. Here is how spray foam insulation will benefit your home.
Open-cell and closed cell
Spray foam insulation is a term that encompasses two types of products: open-cell and closed-cell. Open-cell foam has many advantages compared to closed-cell in terms of R-value and cost. On the other hand, closed-cell foam is denser, meaning that it requires more material. Not only is this product more expensive, but it is also expensive when it comes to the cost per R. open-cell foam has an R-value of 3.5 to 3.7 per inch, while closed-cell foam has a value of 6.9. Regardless of their properties, both types act as natural air barriers and are thus capable of sealing the attic. Although the name would suggest, open cell does not mean that the cells allow the air to move freely. When it comes to moisture prevention, closed-cell prevents water infiltrations.
Owing to the fact that spray foam is a good insulator, you will be able to save a significant amount of money when it comes to heating and cooling. It is common knowledge that in most homes there is a leakage of hot and cold air of about 50%. What the inert polymer does is combat heat loss and air infiltration. You can use it in order to seal possible cracks and crawl space in your attic, not to mention that it will not contribute to moisture-related decay. For this reason, many people consider spray foam insulation to be the way of the future.
If you decide to add a second layer, then go right ahead. Spray foam insulation will make your walls a lot stronger because the foam acts like a glue, meaning that it will hold the roof in place. In terms of application, the product that prevents heat loss is incredibly easy to apply, fact which explains why most contractors work with this product. Just after one application, the product seals and insulates. There is no more need to re-apply it as is the case with other material. As opposed to other material, the inert polymer has an indefinite lifespan.
Taking into consideration that spray foam reduces energy consumption, your home will be greener. Thanks to the protection that it provides, it will no longer be necessary to use the heater and the cooler all day long. In addition to this, the product protects your home from moisture growth. Not only is it water resistant, but the polymer does not provide the mold food. Finally, you will use fewer construction materials.
