Is Your Home Ready for Winter Series - Part 1

Friday, October 07, 2016

Whether your home is heated by a furnace or boiler, heat pump or solar power, Lake Country Repair can service your heating system. Are you ready for tonight 's potential of first frost?

Gas FurnaceRegardless of the type of system of home heating you have it is important to have proper insulation, good air seals and energy efficient windows and doors to help keep your costs down. In the blog we will highlight some good practices to reduce your heating bill.


In Southern Wisconsin it is best to use the following R values for the different pieces of your home:

  • Windows- R 5
  • Foundation Slab: R10
  • Foundation Walls: R20
  • Walls: R40
  • Attic: R60

Most construction does not allow walls to be insulated to the R40 level recommended and it is difficult to add wall insulation to an existing home as the costs are high and the energy gain often too small to offset the expense. Attics however are a different story, it is easy and relatively inexpensive to add blown in insulation to an attic. To get a feel for your homes R value, take a peek into the attic and measure the depth of your insulation. Roughly each inch of blown in insulation adds 3.6 R value so 10 inches of insulation results in an R value of 36.

Air Seals

You can get your home tested for air leakage through a test called the blower door. Lots of air leakage can occur through the basement sill (the area between the top of the basement wall and the 1st floor. Even if you have paper backed insulation in those areas you may want to consider replacing it with expandable foam as this provides a much higher insulating factor and less air leakage. The same is true for the eves of your home. These areas are difficult to access so sealing those is best done during initial construction. But don’t forget your outside wall light switches and power outlets, adding some foam inserts will reduce air leakage and this is an easy project to tackle yourself as the material is inexpensive and the installation only requires a screw driver to take of a switch plate cover adding the foam and replacing the cover. Windows and Doors are other big air leakers.

Windows and Doors

Windows and doors consume a lot of your energy but you would not be very comfortable in a cave without windows! Windows that have a low E coating will help. Storm windows and doors, double or triple pane windows, weather-stripping and caulking will also help making your home comfortable by providing the best possible seal. Having drapes that are closed at night, especially in the winter also helps.

Stay tuned for our next blog in which we will explore the types of heating systems available.
