19. Check insulation levels throughout your house. Measure attic insulation with a ruler, and check behind switchplates for sidewall insulation.

20. Install more attic insulation. Upgrading from three inches
to 12 inches can cut heating costs by 20 percent, and cooling costs by 10 percent.

21. Add pieces of batt insulation to the rim joists – the area along the top of the foundation where it meets the exterior walls.

22. If your basement is unheated, install blanket insulation in between exposed floor joists.

23. When choosing fiberglass insulation, the new “no-itch” or poly-wrapped products are worth the small extra cost. They’re much easier to handle and safer to work with.

24. Additional attic insulation should be installed at right angles to the previous layer. You don’t have to use the same type of insulation – it’s fine to use batts or blankets over loose-fill, or vice versa.

25. When using loose-fill insulation, be sure to distribute it evenly. Any inconsistencies can reduce the insulating value.

26. While shopping for insulation, remember that R-value measures the amount of thermal resistance. The higher the R-value, the better the insulation.

27. Never cover attic vents or recessed light fixtures with insulation, and allow a threeinch clearance around chimneys and flue pipes to prevent overheating and avoid the risk of fire.

28. Have a leaky roof repaired and make sure your basement is waterproofed. Wet insulation is worthless.


R-value measures the amount of thermal resistance. The higher the R-value, the betterthe insulation.
