Insulation Blankets

One popular form of insulation is blanket insulation. It is a blanket made of numerous layers of rock wool, fiberglass, or other comparable materials that can be put on walls, ceilings, and floors. To shield it from moisture and other intrusions, it is frequently sandwiched between heavy layers of paper or cardboard.

If you’re looking to keep prices down, this is an excellent alternative because it’s also one of the most readily available and cost-effective insulation methods.

Glass Fiber Board

Fiberglass board insulation is constructed of layers of fiberglass placed one over the other, much like a fiberglass insulation blanket. Instead of being squeezed into a flexible blanket, the layers in a fiberglass board are compacted into a rigid board. 

ue to its stiffness, this type of insulation might be a little trickier to install. Hence expert installation is advised.

Spray Foam 

In a spray foam insulation method, the space to be insulated is filled with an expanding foam material using specialized equipment. 

For both older and modern mobile homes with irregular wall spacing, this is a very effective insulating solution. A mobile home’s thinner walls are perfect for spray foam insulation because of their excellent ability to fit into small spaces.

Foam boards are also an option if you don’t mind the DIY project of cutting them to size.

Air-Blown Insulation

Blown-in insulation is placed similarly to spray foam insulation by employing specialized machinery to blow the insulation into the space. 

However, loose-fill insulation insulates the space using a combination of loose recyclable materials like cellulose or fiberglass rather than foam. This is a fantastic option for mobile home owners since it fits into small wall openings, just like spray foam insulation. Plus, it’s typically less expensive than spray foam.

How Do I Pick the Best One for My Mobile Home?

Benefits of Replacing the Insulation in a Mobile Home

Better Comfort

It’s not just about saving money when replacing the insulation in mobile homes. There is unquestionably something to be said for more comfort. Better insulation makes it simpler to maintain a comfortable indoor temperature year-round.

R-Value – What Is It?

R-Value comes up frequently when talking about mobile home insulation, but what exactly is it? The R-values of various insulating materials will vary. The ease or complexity of installation, price, and the R-Value you receive for your money and work should all be taken into account when selecting the best insulation.

Generally speaking, heat moves from warm to cool locations. Your home’s heated air will be attempting to escape throughout the cooler months.

The heated air outdoors will be attempting to move within during the summer. This happens as a result of convection and conduction. Let’s examine how materials in your house respond to this natural law:

The R-value of a substance indicates how well it can withstand heat flow. The better it is in insulating your home, the higher the R-value.


Insulation acts to change the conductive property of materials, which is how warm air moves through them. Less hot air will escape through your walls in the winter if you have the proper conduction protection.

How to insulate under a mobile home

The most suggested approach to insulating under a mobile home is to blow insulation into the belly and ceiling of the structure for increased energy efficiency. However, this technique for insulating a mobile home’s underbelly needs specialized tools and an in-depth understanding of how they are built. As a result, blowing insulation might be costly. Fortunately, there are numerous state and local government initiatives that could provide energy subsidies and low-interest loans to mobile homeowners in order to help them add insulation. 

If your mobile home was built before 1976, you might be eligible for a program or funding assistance to improve the insulation.
