Insulation Below A Groundbearing Slab
“…is well suited to new build and refurbishment projects where a timber floor is to be replaced by a concrete floor…”
Insulating below the slab of a ground bearing floor includes the slabs thermal mass in the insulation envelope. This in turn maintains an even temperature in the building.
Insulating a groundbearing floor below the slab brings the thermal mass of the slab within the insulation envelope, helping to maintain the building at an even temperature: the construction is suited to buildings, which are continuously heated. This construction is compatible with masonry wall constructions and under floor heating. Below slab insulation is well suited to new build and to refurbishment projects where a timber floor is to be replaced by a concrete floor.
The properties of Ballytherm insulation match those required for this application: it is robust and moisture resistant, whilst its low thermal conductivity minimises the thickness of insulation within the floor construction.
To determine how thick your Ballytherm below floor insulation needs to be to meet regulations, consult this Table 4.
