Do you own a mobile or manufactured home? How old is it? Here’s why we ask that question…

Only between one and 4 inches of low-quality insulation is contained within mobile homes built before 1976. That is, if there is even any manufactured home insulation present at all! When there is installation present, throughout the home, many builders of that era left gaps and voids. This is no longer the case with manufactured homes, however, thanks to HUD.

Regulation codes set forth by the United States Department of Housing and Urban Development have better assured manufactured homeowners of a safer, higher quality, better built manufactured home since their inception in 1976. Additionally, in the last 40 years, advancements in mobile home insulation have been significant.

If you own an older mobile home, one of the best investments you can make would be to insulate it properly. You can improve your comfort level and reduce your utility costs.

Let’s say you decide to go ahead with an insulation project on your manufactured home. How do you measure it? What exactly does manufactured home insulation consist of? Why do you need it?

Why Insulate Your Manufactured Home?

As already stated, if your home is better insulated, your comfort will be better as well. Nobody wants to wear a snowsuit inside their mobile home just because their walls aren’t properly insulated.

Utility charges aren’t going down anytime soon – if ever. Why not reduce your costs by putting the right kind of insulation in your manufactured home? It is an investment well worth the cost.

Installation – What Kind to Use

There are different “R-values” assigned to insulation. Get the best R-value for your time and money. Also, consider the following when trying to choose which insulation will be best:

  • Total cost
  • Difficulty or ease of installation
  • Safety

Note: R-value refers to the measurement of a material’s ability to resist heat flow. Where the insulation of your home is considered, you will get a more effective result, the higher the R-value.

Types of Insulation

Here are some of the available installations. Think about the above-stated considerations as well as the type you feel would best suit your purposes:

  • Injected or sprayed foam
  • Blow-in or loose-fill
  • Foamboard
  • Blanket (rolls and bats)

What About Fiberglass?

Fiberglass insulation is available in two forms: batt and blown. Fiberglass itself has pros and cons.


  • May trap moisture (though it loses its effectiveness when it gets wet, it doesn’t deteriorate)
  • It may irritate sensitive skin
  • It should never be inhaled
  • “Critters” like fiberglass


  • Extremely flexible
  • Cost-effective
  • Very effective insulator
  • You do need skin protection and breathing masks, but you don’t need any specialized tools

Replacing Fiberglass: Cellulose

In some insulation materials, the place of fiberglass fibers can be taken by cellulose fibers. Recycled paper is used to make cellulose, rather than glass (as is the case with fiberglass). Other insulation materials can include the following:

  • Hemp
  • Straw
  • Wool
  • Cotton

Cellulose also has pros and cons.


  • Particularly if it absorbs water, every five years, it should be replaced
  • Professional installation is usually required, unlike with fiberglass


  • Since recycled materials are used, it is environmentally friendly
  • The risk of lung damage being caused is nonexistent, unlike with fiberglass

Particularly if you have an older mobile home, one of the best improvements you can make is by investing in new insulation.
