FAQ
What type of insulation goes under concrete slab?
Rigid panel insulation with a closed cell structure is the best for under slabs. Expanded Polystyrene (EPS) and Extruded Polystyrene (XPS) are good examples of this.
What is the R value of concrete slab?
The R Value of a concrete slab is minimal without insulation. 150mm of concrete in approximately only R0.1
How do you insulate a concrete slab?
The rigid panel insulatiuon should be installed on top of the water proof membrane and below the mesh. Concrete is poured as normal.
How do you insulate a slab floor?
The rigid panel insulatiuon should be installed on top of the water proof membrane and below the mesh. Concrete is poured as normal.
How thick should a slab be for a house?
The slab for a house is designed by an engineer and is usually a minimum of 100mm
How deep does a concrete slab need to be?
Similarly, the deepness of the slab for a house is designed by the engineer and is usually a minimum of 100mm
Do I need a vapor barrier under my concrete slab insulation?
Yes, vapour barriers are essential because concrete is poured wet, it needs to dry and then stay dry to avoid flooring problems.
How thick should concrete floor insulation be?
The thickness will be dependent of the material and the requirement of the project. The requirement is listed in the energy report.
How thick should a concrete slab be for a garage?
The slab for a garage is designed by an engineer and is usually a minimum of 150mm.
What is the purpose of a vapor barrier under concrete slab insulation?
The purpose of a vapor barrier is to separate the concrete from the moisture in the ground. This allows the concrete to dry after pouring and stops the concrete from absorbing moisture after curing to prevent movement or other problems.
