Difference Between Crawlspace Insulation And Attic Inuslation

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

Difference between crawlspace insulation and attic inuslation.

Insulate water heaters to prevent costly energy loss. The table below shows what levels of insulation are cost effective for different climates and locations in the home. A crawl space isn t a livable part of the home but insulation is still important to keep the heat in. Insulation ratings can be improved by adding more layers of insulation.

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. Foam board insulation is easy to use and is a great diy way to add some insulation. The higher the r value the better the thermal performance of the insulation. Crawl spaces can be a major source of energy loss.

Some types of thicker foam board insulation are available but they may need to be special ordered. Look for insulating pre cut jackets or blankets with an insulating value of at least r 8. Make sure your home is properly insulated in all these locations. Insulate your attic outer walls and crawl space first as these areas have the most heat transfer.

Insulation level are specified by r value. 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. You can mix the type and material of insulation too. R value is a measure of insulation s ability to resist heat traveling through it.

It comes in standard size 4 8 sheets and smaller sizes in many different thicknesses from 1 4 inch to 2 inches.
