Insulation under concrete slab detail.

This technique can limit inward vapor movement when the sun shines on damp bricks. Under slab 5 more ways to filter. View product details. A continuous layer of horizontal insulation reduces heat loss in the winter and it reduces condensation of humid air on the slab during the summer.

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 above the slab can be more appropriate. Get all the construction. Slab edge may be responsible for about 60 of the slab s total heat loss certainteed effect of slab edge insulation rem design simulations 8 increase in total heating consumption with no slab edge insulation 62 of heat loss through slab edge 16. Water resistant rigid board for under concrete slab insulation and slab support in traffic bearing applications.

Rigid insulation is placed horizontally under the slab perimeter and vertically in the joint at the slab edge. Slabs that include embedded hydronic tubing for radiant heat always need a continuous layer of horizontal insulation under the entire slab. Under the slab to maintain a seasonal average slab temperature that is 10 f above the seasonal average soil temperature through a heating season lasting from october 1 through april 30 a slab insulated with 1 inch of foam would lose 7 1 million btu more than a slab insulated with 2 inches of foam. Eps 3 xps 2 faced or unfaced.

Continuous insulation is applied directly to the underside of the slab and extends inward horizontally from the perimeter for the distance specified or continuous insulation is applied downward from the top of the slab and then extends horizontally to the interior or the exterior from the perimeter for the distance specified. Prodex exhibits less than 9 compression in thickness when subjected to loads associated with standard concrete floor systems. Under slab insulation specifically designed to withstand the weight of a concrete slab and the rigors of foot traffic. Additionally a layer of rigid foam is used between the framing and ventilation space behind the brick cladding.

Below grade under slab with foamular xps insulation. Insulation below the slab suits continuous low level heating gradually warming the thermal mass of the concrete and sustaining it at a consistent temperature.
