Concrete Ground Floor Slab Insulation

Typically the insulation would be situated below the slab and below the damp proof membrane for heavy duty use whilst normal domestic buildings would have a.

Concrete ground floor slab insulation.

Submitted in 2016 for drc step 3 construction documentation review was an. Ground floor insulation below concrete slab thermal insulation is usually installed below the floor slab in buildings featuring continuous low level heating. These overall r values do not account for the heat sinking effect of concrete piers where they are included to support a slab footing from below. It helps make effective use of the thermal mass of the concrete slab rather than repeatedly warming it and allowing it to cool.

Otherwise both codes require that slab on grade floors with a floor surface less than 12 in. Ground bearing floors shall be of adequate strength and durability and use concrete mixed and reinforced as necessary to support floor loads safely and resist chemical and frost action. Suitable product for concrete slab on ground floor. These codes do not require any insulation for slabs that are more than 12 in.

The codes are silent about whether above grade slabs need to be insulated. Kooltherm k3 floorboard is a super high performance fibre free rigid thermoset closed cell phenolic insulation for solid concrete ground based floors. Eps can be a cost effective alternative to pir for floor insulation and the same thermal performance can be achieved with increased thickness. This stops any thermal bridging across the walls leading to cold spots.

Insulating a solid ground floor below the ground bearing concrete slab can be done using either pir insulation boards or eps insulation boards. 4 10 2012 3 climate zones e301 1 6 5 8 4 slab r value table 402 1 1 insulation and fenestration requirements by component e402 1 1 climatezone slab r valued 4 10 2 ft 5 10 2 ft 6 10 4 ft 9. Alternative solutions 4 and 5 for continuous insulation of on ground concrete floor slabs. Below grade need vertical insulation at the slab perimeter.

For the floors of industrial. Where the heating is likely to be turned on and off such as in new build domestic properties and a faster thermal response is required the floating floor arrangement of. Insulation below the slab suits continuous low level heating gradually warming the thermal mass of the concrete and sustaining it at a consistent temperature. Ground bearing concrete floor slabs should be at least 100mm thick including monolithic screed where appropriate.
