Classification data | |
Standard | To BS EN 13164. Guidance for specification option: Manufactured in accordance with BS EN 13164, ISO 50001 Energy Management Systems, OHSAS 18001 Occupational Health and Safety Management Systems, ISO 14001 Environmental Management Systems, and ISO 9001 Quality Management Systems, as certified by Bureau Veritas. |
Third-party certification | BES 6001, UKCA, UKNI & CE Marked to BS EN 13164 and conforms with the Construction Products Regulation, BBA 17/5454, Environmental Product Declaration; BBA Certificate 17/5454. |
Fire performance | To BS EN 13501-1, Class F. |
Compressive strength (minimum) at 10% compression | 300 kPa. Guidance for specification option: Highly resistant to compression and withstands both occasional and long term static loads. The high compressive strength and rigidity of the product allows a range of ballast material 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) | 0.031 W/m·K. |
Thickness | 50 mm. |
Face size (length x width) | 1250 x 600 mm. |
Edges | 15 mm lap joint. |
Global warming potential | <5. |
Service temperature | Up to +70ºC. Guidance for specification option: Continuous service temperature. |
Thermal resistance | 1.60 m²K/W. |
Water vapour resistance | 705 MNs/g·m. Guidance for specification option: When tested in accordance with BS EN 12086. |
Water absorption | Moisture absorption of 0.9% by volume when tested in accordance with EN 12087. |
