Insulation is one of the most important things that a house should have when it comes to keeping energy costs under control. Unfortunately, it is possible for insulation materials to become worn-out and unable to work in a thorough manner after being installed for a long time. The problem with worn-out insulation is that many homeowners neglect to replace it due to believing that it will require extensive demolition of drywall. Although it is necessary to place the new insulation materials behind the drywall, it doesn't necessarily mean that a lot of demolition must be done, especially with specific types of insulation. The most ideal way to avoid the need for demolition is to opt for an insulation material that can be sprayed into the wall cavities.
The Safety of Spray Foam Insulation
If you get spray foam insulation installed in your house, your safety should not be a concern. The reason why is that the spray foam is completely safe to be around after installation is complete. Your main concern will be the gas that is released into the air during the actual installation process. However, you will not be subjected to the gas because it will be necessary for everyone in your household and pets to leave the house for at least 24 hours, although it could be longer. After the allotted time has passed, the gas will no longer be emitted from the spray foam insulation.
How Insulation Is Sprayed Into Wall Cavities
In order for a contractor to place spray foam insulation into the wall cavities in your house, access to them must be made through drywall. However, unlike with the installation of other types of insulation materials, demolition will be unnecessary. The reason why is that only one or more small holes will need to be made to install the spray foam, depending on how many walls are being insulated. The perk of using small holes over extensive demolition is that they can quickly be patched up during the installation process. Basically, equipment will be used that sends foam that expands into the wall cavities via the small holes, and then patchwork will be done by the contractors.
Spray Foam Insulation and Energy Efficiency
There are different types of spray foam that have various energy efficiency levels. If you want the maximum amount of energy efficiency, closed-cell spray foam is the way to go. However, you will likely be satisfied with any spray foam insulation type that you choose.
