Concrete Ground Floor Slab Insulation

The target u value for a concrete ground floor slab is 0 22 and these days the insulation must be provided around the edge of the floor slab as well.

Concrete ground floor slab insulation.

These codes do not require any insulation for slabs that are more than 12 in. 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. 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.

If your concrete floor is for industrial or heavy duty applications then any insulation you use needs to have a high compressive strength to take the weight of whatever is above. Ground bearing concrete floor slabs should be at least 100mm thick including monolithic screed where appropriate. Insulating a solid ground floor below the ground bearing concrete slab can be done using either pir insulation boards or eps insulation boards. Our businesses in australia.

Eps can be a cost effective alternative to pir for floor insulation and the same thermal performance can be achieved with increased thickness. Ground floor insulation below concrete slab thermal insulation is usually installed below the floor slab in buildings featuring continuous low level heating. For the floors of industrial. 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. 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. This stops any thermal bridging across the walls leading to cold spots. 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.

It helps make effective use of the thermal mass of the concrete slab rather than repeatedly warming it and allowing it to cool. Submitted in 2016 for drc step 3 construction documentation review was an. 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. Insulation below the slab suits continuous low level heating gradually warming the thermal mass of the concrete and sustaining it at a consistent temperature.
