Installing insulation inside the walls of a mobile home

5 Most Common Types of Mobile Homes Insulation

As with any building, insulation is always one of the most important aspects to consider, whether for housing or industrial purposes. That applies to manufactured homes in Fernley, Nevada, as these come with many other challenges and factors that might affect the effectiveness of your insulation.


However, installing too little or too much could result in higher energy bills and poor indoor air quality. That’s why choosing the right type of insulation for your home is important!



To insulate the inside walls of mobile homes, workers shred paper or cardboard into small pieces, mix it with water to create a thick slurry, and then spray it onto the walls. The result is cellulose insulation.


Cellulose insulation is inexpensive and eco-friendly as it comes from recycled materials. It also doesn’t contain harmful chemicals or other additives that could harm you and your family.


Due to its affordability and easy installation process, mobile homeowners often prefer this option. However, the best thing about cellulose is that it offers great value thanks to its ability to conserve energy by up to 26.4%.


Spray Foam

Spray foam is easy to install because the material comes in pre-measured spray cans, ready for immediate use. You don’t have to spend time cutting pieces to fit your space or wait for the delivery of those large rolls.


The drying time depends on a few factors, including application thickness and the temperature in your area. It usually takes between 5 and 60 minutes for a coat to set up. Still, it can take longer, depending on the humidity.


This type of insulation is great for mobile homes as it can fill large gaps, like the spaces between framing members. You may also use this to fill in smaller gaps between components like windows and doors.


Rigid Foam

Rigid foam derived its name from its ability to stay solid despite pressure application. Thus, it’s not as effective at insulating against heat loss as other types of insulation that can compress, like fiberglass or cellulose.


Closed-cell foam doesn’t allow water vapor to pass through. Thus, rigid foam insulation is ideal for use in areas where moisture control is important, like bathrooms and kitchens.


Rigid foam is less expensive than rock wool but more expensive than cellulose. It’s more effective than fiberglass because it is lightweight, sprayable, and can be installed in areas with no studs or joists. 



Fiberglass is a mineral that’s been heated and spun into strands. It’s then mixed with resin and other materials to create a foam that can be used in insulation.


It’s lightweight, so it doesn’t add a lot of weight to the structure of your home. It’s also fire-resistant, which makes it ideal for protecting against heat damage.


There are two forms of fiberglass insulation: loose-fill and batts. Both are made from glass fibers and plastic resin and are available in varying thicknesses.


Rock Wool

For thousands of years, people have been using molten rock to make rock wool. Rock wool consists of slag, a byproduct of steel production.


Not only is it a natural insulator, but it is also fire retardant and soundproof. You can easily install it with either scissors or a knife.


Rock wool has a low density of about 1/3 of that of regular concrete. Thus, it can keep homes cool in the summer and warm in winter.


Mobile home insulation is important in retaining heat and keeping the inside temperatures comfortable. Maximum insulation is provided by insulating walls, floors, and ceilings with the five types of insulation listed above.
