Best answer

Designers generally insulate both directly under the slab and around the perimeter as well. In cold climates it is advisable to use a minimum of 2 inches of extruded polystyrene under the slab. Many increase the under-slab insulating foam board thickness to 3 or 4 inches at the outer 2 to 4 feet of the slab.

How thick should my concrete slab be?

Asked By: TheUnreal Date created: Jun 12, 2022

4 inchesStandard concrete floor slab thickness in residential construction is 4 inches. Five to six inches is recommended if the concrete will receive occasional heavy loads, such as motor homes or garbage trucks. To prepare the base, cut the ground level to the proper depth to allow for the slab thickness.

What do you use to insulate a concrete floor?

Asked By: RameshVel Date created: Jun 19, 2022

Solid floors are insulated using rigid insulation foam, which can be fitted either above or below the concrete. If the concrete is above the insulation it can sometimes store heat during the day, which helps keep the room warm at night.

Floors: A 1/4-inch minimum thickness is needed, but thicker panels are also fine. Walls: Use 1/2-inch or 5/8-inch-thick cement board, not 1/4-inch. The extra thickness is needed to span the studs and provide a solid base for the tile.

How do you insulate a cement floor?

Asked By: Michael Jungo Date created: Jun 20, 2022

There are two ways to handle insulating concrete floors. You can attach wood sleepers to the floor, fill the gaps with rigid-foam insulation, and then apply your finish flooring. Or, as demonstrated here, you can cover the slab with rigid-foam insulation, add two layers of plywood, and then add the finish flooring.

Can a concrete slab be too thick?

If the slab is too thin, it may break under load and fail before its time. If the slab is too thick, it costs more than it should. Slab thickness is a major factor in the cost of a concrete floor, so there's often pressure, which can become intense, to make the slab as thin as possible.

Do I need to insulate a concrete floor?

For solid concrete floors, make sure that if they need to be replaced, your builder puts in insulation – you have to insulate a floor when it is replaced in order to comply with building regulations.

How do you protect concrete from frost?

Reinforcing bars and shuttering must be free of ice and snow. Cover and insulate the concrete where possible. If concrete has to be placed it should be organised so that it is done as quickly as possible. Frost blankets should be used to provide insulation and protection for exposed concrete surfaces.

What is the best insulation for under a concrete slab?

Applying a bead of polystyrene-compatible caulk or mastic to the top of the insulation board minimizes water infiltration behind it. For under-slab applications, the rigid foam insulation typically should be installed over a gravel base, with a poly vapor diffusion retarder between the gravel and insulation.
