Third party product certification	UKCA, UKNI & CE Marked to BS EN 13164, BBA certified and conforms with the Construction Products Regulation.
Compressive strength (minimum) at 10% compression	500 kPa. Highly resistant to compression and withstands both occasional and long term static loads. The high compressive strength and rigidity of the boards allows a range of ballast materials including gravel, soil and concrete slabs to be used as part of the construction. Load bearing construction elements should be designed to adequately support the combination of imposed and dead loads without creating excessive deflection.
Thermal conductivity (maximum)	0.034 W/m·K.
Thickness	50 mm.
Face size (length x width)	1250 x 600 mm.
Edges	15 mm lap joint.
