Ground Floor Insulation Detail

These overall r values of slabs as constructed do not allow for thermal bridging caused by discontinuities in compressible extruded polystyrene xps insulation as may be necessary where the slab underside bears on concrete.

Ground floor insulation detail. Installing floor insulation above the slab and below the screed. For low rise buildings on poor ground the floor slab can be designed as a raft to act as the foundation. It helps make effective use of the thermal mass of the concrete slab rather than repeatedly warming it and allowing it to cool. You can unsubscribe at any time and we ll never share.

View our range of floor insulation here. This insulation strip should be the full depth of the concrete slab and the top edge should be level with the top of the floor screed. See selecting the right grade of floor insulation for your product below. The ground floor beneath a house is generally warmer than the air around it and so it would perhaps be third on your list of priorities behind walls and roofs.

Jablite floor insulation is manufactured to a range of compressive strengths providing a solution for every type of ground floor application. Unbuildable solution assumed by nathers for continuous insulation of on ground concrete floor slabs. Alternatively blanket insulation will need to be held up by netting and tacks stuck into the joists. While celotex pir boards have a good compressive strength they cannot be laid below a raft slab and take the structural load of the building.

Skip to main content. Ground floor insulation below concrete slab. Ground bearing floors can include insulation either below or above the concrete slab depending on the choice of the designer. And for all other general enquiries contact us on the details below.

For perimeter edge insulation fit a continuous vertical strip of quinn therm qf insulation boards at least 25mm thick around the floor perimeter against the walls to avoid heat loss through thermal bridging. Kingspan vips offer an ultra thin build up of just 26mm image credit. No spam we promise. Exposed wood framed floor insulation insulating the exposed floor can make the space more comfortable reduce the incidence of frozen pipes help stop mold problems and help save on overall energy costs.
