Difference Between Crawlspace Insulation And Attic Inuslation

Adding insulation to your water heater can reduce standby heat losses by 25 to 45 percent.

Difference between crawlspace insulation and attic inuslation.

It comes in standard size 4 8 sheets and smaller sizes in many different thicknesses from 1 4 inch to 2 inches. However when adding multiple layers of insulation you want to make sure that only one layer has faced and that the facing does not lie against the second insulation layer. The ideal attic insulation r value is different than the ideal wall insulation r value. A crawl space isn t a livable part of the home but insulation is still important to keep the heat in.

If you find yourself running your furnace all winter long driving up high energy bills yet still feel cold on the ground floor of your home your crawl space could be the issue. The table below shows what levels of insulation are cost effective for different climates and locations in the home. Crawl spaces can be a major source of energy loss. R value is a measure of insulation s ability to resist heat traveling through it.

The higher the r value the better the thermal performance of the insulation. Look for insulating pre cut jackets or blankets with an insulating value of at least r 8. Insulate your attic outer walls and crawl space first as these areas have the most heat transfer. Insulation level are specified by r value.

Achieving greater r values in attics. Insulation ratings can be improved by adding more layers of insulation. You can mix the type and material of insulation too. Insulate water heaters to prevent costly energy loss.

Insulation facing is a moisture or vapor barrier so it only makes sense to use faced insulation in your crawl space.
