Insulation and Weatherization Tips

 

Hints for Staying Comfortable


  • Caulk and weather-strip doors and windows that leak air.
  • Seal air leaks between your living space and your attic and/or crawl space. Leaks are common around plumbing and vents, heating ducts, light fixtures and wires. Be sure that fixtures and wires are designed for direct insulation contact.
  • Install wall plate insulation gaskets behind outlet and switch plates on exterior walls (turn off the power before installing gaskets).
  • Install a 6-mil vapor barrier between your living space and your crawl space to prevent moisture from entering your home.
  • Make sure your attic and crawl space have adequate ventilation to vent out moisture and summer heat.

Selecting/Installing


  • The effectiveness of insulation is noted as an R-value, a measure of the material’s resistance to heat transfer. Higher R-values provide greater insulating value. R-values are additive – the more you add, the higher the R-value will be.
  • Use a ruler to check the existing insulation levels in your attic, ceilings, exterior walls, floors and crawl spaces.

8.10 R-30 13.75 R-30 9.00 R-30
10.0 R-38 17.50 R-38 12.00 R-38

 

  • Add new insulation to the existing insulation to increase the R-value using the following guidelines:

House Area

Standard

Enhanced

Attic/Ceiling R-38 R-50
Floor (over unconditioned space) R-19 R-30
Wall R-13 R-19

 

  • Use higher density insulation that has a higher R-value per inch of insulation in cathedral ceiling and in exterior walls.
