How Well are Manufactured Homes Insulated?

Insulation is put in homes to help keep a consistent temperature and to lower heat transfer. That means insulation helps prevent loss of heat during the winter and also helps prevent heat from entering your home during the summer.

 

Having high quality insulation in your manufactured home is a smart choice. It can help keep energy costs low because your heating and cooling system doesn’t have to work as hard to maintain a certain temperature.

 

What kind of insulation do Clayton manufactured homes have?

Clayton manufactured home insulation R-values will vary based on the home and its final location, but if you purchase a home with Clayton’s optional Energy Smart Home package, the manufactured home floor will have R-22 insulation, the ceiling will have R-33 (R-30 for vaulted ceilings) insulation and the walls will have R-11 insulation.

 

As part of the Clayton Built® standard, our homes are built with tight construction and quality insulation. You’ll find quality insulation in the floors, walls and ceilings as well as other parts of your manufactured or modular home like the duct system.

 

So, what exactly do these R-values mean?

The “R” in R-values stands for “resistance,” or the ability of the insulation to resist heat transfer. The higher the number, the higher resistance that the insulation has against heat passing through.

 

You may have heard that heat rises, which is why the ceiling insulation usually has the highest R-value. This helps prevent the heat from escaping through the roof area during the winter.

 

HUD Code and Home Heat Transfer

The HUD Code, which was implemented in 1976, brought more stringent requirements that meant manufactured homes must be built to a specific standard. For instance, the HUD Code outlines a maximum U/O value, which is the heat transmission level, for manufactured houses.

 The U/O Value Zone Map will determine the insulation that goes into your home to ensure that heat transfer in your home does not exceed the HUD Code maximum.

 

Insulation Safety Requirements

HUD Code also has fire safety requirements for insulation. For example, there are flame-spread rating requirements for insulating materials that go into manufactured homes. These flame-spread rating requirements help improve fire safety in your home.

 

In addition, HUD Code also outlines smoke-developed rating requirements for insulating materials. The smoke-developed index is a measure of how much smoke a material gives off as it burns, so having a maximum in place for manufactured home insulation helps increase homeowner safety in case of a fire.

 

Tight Construction Combined with Home Insulation

The tight construction of each manufactured home also helps prevent drafts, air flow, dust, pollen and other things in the air from entering your home. This tight construction combined with the quality insulation placed in the floor, walls and ceilings helps make manufactured homes consistently comfortable and can help lead to lower utility costs!

 

Clayton Built® homes are constructed with families like yours in mind, so we use quality insulation in every manufactured and modular home we build. This includes our insulation that complies with requirements to help keep you and your family safe as well as requirements that help keep your home more comfortable all year long.
