Insulating Your Manufactured Home: Why and How

Posted on

When you purchase a manufactured home, you usually think that it is properly insulated for your needs. But especially in older manufactured homes, there are additional energy-saving measures that can help save you money in heating and cooling costs every year. 

Why Use Blow-in Insulation in Your Attic?

Typically, manufactured homes don't have a lot of space in the attic. That makes them easier to build and to transport from the factory. But it makes it harder to improve insulation in the attic. Blowing in insulation is the best way to do this.

There are three main ways to add roof insulation to a manufactured home:

  1. Interior blow. Drill holes in the inside ceiling and blow insulation in from the inside.
  2. Ridge blow. Drill a series of small holes and blow insulation in from the top.
  3. Edge blow. Roll back the edge of the roof and blow insulation into the open cavity.

None of these methods can be done by a do-it-yourselfer because of the risk of creating leaks or even misaligning the roof when you put it back. You must hire a professional insulation company, such as Discount Energy Services.

Types of Blow-in Insulation

There are two main types of blow-in insulation: 

  • Fiberglass insulation, which is made of tiny glass fibers that trap heat in order to insulate.
  • Cellulose insulation, which is made from insulating paper fibers treated with fire retardant. 

The two types have similar insulating values, also called R-values. Initially, cellulose insulation is slightly better at insulating but it can settle over time and leave some areas uncovered. For the most part, the two types will provide adequate insulation in your mobile home attic.

However, fiberglass insulation is lighter weight and does not absorb water, making it a more preferred solution for manufactured homes. Your insulation expert can evaluate your environment and specific manufactured home to help you determine which option is best.

Other Ways to Insulate

You don't need to stop with your attic. Manufactured homes can also use additional insulation in the walls and underneath the floor. In order to save the most money on your energy bills, you should also:

  • Make sure doors and windows have new, undamaged weatherstripping. 
  • Caulk any gaps or holes around door and window openings.
  • Seal openings around plumbing fixtures.
  • Install energy-efficient heating options.

Careful attention to energy use can save you money on utility bills and make living in your manufactured home even more cost effective.
