Mobile Home Weatherization – Underbelly


By updating your mobile home, you have the biggest opportunity to save on heating and cooling bills by tackling the windbreak of the House. Due to the construction process of the plant by which they are built, they have a large open cavity between the insulation of the bottom board and the lower part of the subfloor. This cavity is called the "lower belly". Some houses have more than others under the limits of their limits. Typically, when you perform air sealing measurements on the house, you will get the greatest reduction in air infiltration by filling the vacuum that is the under- belly. There is little or no insulation directly behind the rim joist, which gives the house a broken thermal envelope. Blowing insulation in the wind will not only provide the home with a real thermal limit, but would greatly reduce air infiltration by closing the vacuum. This is done by using an insulating blower machine coupled to about 100 'of pipes. Most large box stores offer machine rentals. Insulating blown glass fiber should be used in place of cellulose. Fiberglass is naturally waterproof, making it a better choice by comparison.

  • Patchwork – The first thing to tackle before isolating the windbreak is tears or holes that the bottom board might have. If these are not repaired, there is nothing to retain the insulation. The most cost – effective way to do this is by using a house envelope "Tyvek or Typar" as the closure material. You can staple the existing material or you can use screws and washers for the bottom of the floor joists. For smaller holes or to seal the patches, two-piece foam insulation works well.
  • Blowing insulation in the center of the mobile home – The key to insulation blowing is to know where to place the material. The mobile homes were designed so that the plumbing lines cross the ground near the heat pipe so as not to freeze during the winter months. The center of the house, where the plumbing lines exist, must be blown with a low density. Do not over-insulate, otherwise the heat from the heat pipe can not reach the pipes, and they will definitely freeze. You want to install the insulation at the point where you fill the cavity, but the material still has lint or mouth.
  • Blowing insulation at the perimeter – Insulation blowing around the house, including the ends only if they do not have plumbing, is 39 Where you get the most bang for your money. The perimeter is defined as outside the I-Beam sections. Still paying attention to the plumbing, there are usually some of those sections that have plumbing. Blow the insulation to a maximum density, completely fill the vacuum and pack the material. This is where you stop the air infiltration and the radiant heat loss / gain from the bare rim joist. Treat the ends of the center in the same way, if there is no plumbing.
  • Entry point – Access to cavities can be done in two ways. Remove contours or facing on the outside and drill holes through the joist of the rim is an option. An aluminum pole attached to the insulating blow pipe is generally used to enter the cavity. The other is crawling into the house and cutting holes in the bottom board, inserting the hose directly and packing the holes when they are complete. Both have their advantages and disadvantages.

By keeping these ideas in mind, you can easily and securely resist the loss of your mobile home.
