Should I Install Spray Foam in My Mobile Home?

Install Spray Foam in Your Mobile Home | FOAMETIXMobile homes are often a special consideration when it comes to insulation. As these homes are often suspended off the ground, the floors are often thickly insulated with fiberglass batt or blown-in cellulose.

Unfortunately, this type of material can become a magnet for small creatures to burrow in or become wet due to adverse weather. These types of issues make the insulation far less effective and can cause energy bills to skyrocket.

These obvious flaws have caused some owners to start looking for alternative solution. One of the more popular options has been to replace the old insulation with spray foam for mobile homes.

What is Spray Foam?

Spray foam is a two-part chemical made primarily from polyurethane that expands to fill every crack and crevice in the area. After it cures or dries, the foam forms a sturdy material that creates an airtight seal.

This process is designed to prevent air loss from a home, which is responsible for up to 40% of a house’s energy loss. By eliminating this drafts, your monthly utility costs should lower dramatically while your home becomes a comfortable and energy-efficient dwelling.

What Type of Spray Foam Should I Use?

The most popular version to use is called closed cell or 2 inch foam, which not only provides the highest R-value on the market, but is also hydrophobic. This means that water will run right off of your insulation, keeping your home warm and dry.

This foam is also difficult for rodents and other small animals to infiltrate, as it is a stiff material that is not attractive for nesting. This not only means that vermin will not make your house their home, but that you have a floor that is fortified against destructive insects such as termites.

Where to Spray Foam?

While it might be tempting to line your entire mobile home with closed cell spray foam insulation, this would not be beneficial to your HVAC system or comfort. Sealing your entire home would cut some necessary airflow that help keep your plumbing and heating and cooling system working properly.

Instead, closed cell foam should be used on the roof and underneath the floor. This application should be made from the outside of the home, to ensure that the floor is completely sealed against external forces.

Should you choose to insulate your home with spray foam, be sure to talk to your contractor first about the brand of spray foam that will work best for you. If possible, choose a closed cell, green product that is made from renewable materials, as this is not only more beneficial for the environment around your home, but also is healthier and safer for you and your family.
