How can I tell how well my mobile home is insulated?
Saturday, June 16, 2018
To determine the exact level of insulation in the floor, walls, and ceiling of your home, check the manufacturer’s data plate. It is usually located on the wall of the master bedroom closet or inside of cabinet door at the kitchen. Halfway down the right side column you will find the type of data shown below, which is from a 2002 home. The insulation rating is in “U” values, and the lower the U-value the higher the insulation level.
But most people are used to describing insulation based on the R-value, which happens to be the mathematical inverse of the U-value. So, for example, the R-value of the insulation of the walls of this home is 1 divided by .048, which is approximately R-20. The ceilings would be 1/.058 = approximately R-17, and the floors are 1/.034 = approximately R-30.
Air leakage around the doors and windows, along with any other seams and small openings in the exterior surfaces of the home, which is often referred to as the home’s “envelope,” will lower the energy efficiency no matter what the R-values. So keeping up with the the caulking around the exterior and making sure the belly board is intact will help to bring down your energy bills.
Manufactured/mobile homes tend to have a lower level of insulation than site-built homes built in the same era. But HUD has upped the insulation requirements over the years.
