Cordek
Cellcore HX Plus sits beneath reinforced concrete floor slabs to protect against ground heave while also insulating. Construction is a cellular expanded polystyrene core bonded to a Filcor insulation layer and protected by a thin polypropylene sheet, moulded to tolerance. BBA certified and meets NHBC Technical Standards. Specification is a two-step process Cordek set out explicitly: first fix the Cellcore HX depth and grade to suit the heave potential and the construction loading, then calculate the Filcor insulation thickness needed for the target U-value. Standard range covers common combinations of soil heave potential, concrete depth and U-value requirement.

Kingspan Insulation
The manufacturer data behind a lambda-value comparison. Kooltherm K106 is a phenolic insulation board with a declared thermal conductivity (lambda value) of 0.019 W/mK across all thicknesses, quoted in accordance with BS EN 13166:2012+A2:2016 for factory made phenolic foam products. Boards are 1200mm long by 450mm wide for full fill cavity use with a 10mm residual clear cavity. Thermal resistance is thickness in metres divided by conductivity, rounded down to the nearest 0.05 m2K/W, giving 4.70 m2K/W at 90mm and 6.05 m2K/W at 115mm. Declared compressive strength is 100 kPa tested to BS EN 826:2013. Kingspan states the board can have an indefinite life if correctly installed, depending on the supporting structure and conditions of use, and it is covered by BBA Certificate 16/5299 for 90mm and 115mm and a BBA certificate spanning 25mm to 150mm thicknesses. Note this is a phenolic board, not PIR, so it should not be used as the PIR figure in a comparison.
