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 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.
- 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.
|Cellulose||Blown-in Fiberglass||Fiberglass Batting|
- Add new insulation to the existing insulation to increase the R-value using the following guidelines:
|Floor (over unconditioned space)||R-30||R-38+|
- Use higher density insulation that has a higher R-value per inch of insulation in cathedral ceiling and in exterior walls.
