There will be a damp proof membrane under the insulation and possibly a second membrane on top depending on the type of screed.
Under concrete floor insulation.
Insulation is laid on the concrete and covered with a screed.
The reflectix concrete slab insulation is an innovative easy to handle product that increases the energy efficiency of radiant floor and snow melt systems under concrete.
Insulation below the slab suits continuous low level heating gradually warming the thermal mass of the concrete and sustaining it at a consistent temperature.

In this scenario a rigid foam insulation is usual and as you d want the same u value in the roof we need the same thickness of insulation 180mm.
This allows an area for insulation and fill material under the slab.

Foilboard for underfloor insulation can be used in.
Another option for insulating your concrete floor are some more flexible materials such as knauf rock wool insulation slabs or rockwool insulation slabs which also offer a level of sound insulation apart from known as being great and versatile insulators.
Insulating a slab on grade depends on at least four factors.
The climate the type of foundation whether the slab includes hydronic tubing for radiant heat and the severity of the local termite problem.
Martin holladay explains insulating a slab on grade in the energy smart details department.
For installation on concrete foundations and under floor slabs the rigid foam insulation you choose can make a difference of tens of thousands of dollars on a project.
The good news is that all the mentioned products can be found right here at insulation shop.
The foil within the product acts to spread out the heat signature of the heating coils.
For existing sites without any floor insulation foilboard is a perfect option to improve thermal resistance and reduce energy costs within a home or building it can be easily installed by accessing the underside of the building and fixed to the underside of joists using our.
