The Cellecta HEXATHERM XDRAiN range is a specialist XPS insulation board designed for inverted flat roof applications where efficient water drainage, high compressive strength and long-term thermal performance are essential. Available in a range of thicknesses, these boards provide a flexible insulation solution for domestic, commercial and industrial roofing projects throughout the UK.

Unlike conventional roof insulation boards, HEXATHERM XDRAiN features integrated multidirectional drainage channels on the underside, allowing rainwater to disperse quickly regardless of the board orientation. This innovative design removes the need for a separate drainage layer, making it particularly suitable for green roofs, ballasted roof systems and other inverted roof constructions.

Manufactured using a closed-cell extruded polystyrene (XPS) structure, Cellecta XDRAiN provides excellent resistance to moisture with long-term water absorption below 0.7%, helping maintain its thermal performance over the lifetime of the roof. With a compressive strength of 300kPa, it is engineered to withstand the loads commonly found in demanding roof applications.
