How thick should insulation be between floors?

The U-value is a measure of how quickly heat will travel through the floor. To achieve this standard, you will normally need at least 70mm of high-performance foam insulation, or 150mm of mineral wool, but this will vary depending on floor type, shape and size.

Is it worth insulating between floor joists?

How do you insulate a cabin floor?

The very best way to insulate a floor over a crawlspace is from above, with two inches of extruded polystyrene foam placed over the floor inside, then a new 5/8″ plywood subfloor added on top. This makes a huge difference to the warmth of the floor, and the insulation is safe from vermin.

What insulation should I use in my ceiling?



Depending on where you live and the part of your home you’re insulating (walls, crawlspace, attic, etc.), you’ll need a different R-Value. Typical recommendations for exterior walls are R-13 to R-23, while R-30, R-38 and R-49 are common for ceilings and attic spaces.

How do you insulate a below ceiling?

A self-supporting ceiling is installed beneath the existing ceiling and insulation material is put in between (for example rock wool, fibreglass, PUR or cellulose insulation). Another option is to blow cellulose insulation into the free space between the floor and the ceiling below.

How much heat is lost through the floor?

10 percent



More than 10 percent of an average home’s heat is lost through the floor. This percentage can be much higher in older homes with hardwood floors—or floors made of other materials that conduct heat and cold.

Do you lose more heat through walls or ceiling?

On inspection, you’ll be able to see how much insulation there is, and possibly what type. Looking up your type of insulation will allow you to determine if it should be replaced or increased in its R value. A home energy audit may find that the walls are actually the most significant cause of heat loss in your home.

Can you insulate under hardwood floors?

One way to keep a hardwood floor more temperate is to add insulation in the subfloor. The home improvement site HomeAdvisor says this step will not only make your floor more comfortable, but will also allow for more efficient heating of the home and protect the floor from possible damage by moisture infiltration.
