56mm Cellecta Hexatherm XMD boards combine the superior thermal performance of HEXATHERM extruded polystyrene (XPS) insulation with a robust, high-impact facing board to provide a durable and effective solution for protecting inverted roof vertical upstands. Specifically designed for use within inverted roofing systems, 56mm Hexatherm XMD boards deliver excellent resistance to moisture, impact damage and weather exposure, helping to maintain the long-term integrity and performance of the roof structure.
The high-strength facing board offers enhanced protection against mechanical damage, while the closed-cell XPS core provides outstanding thermal insulation and water resistance. This combination makes 56mm XMD boards an ideal choice for safeguarding parapet walls, roof perimeters and vertical upstands in both commercial and residential roofing applications.
Easy to install and engineered for long-lasting performance, 56mm Cellecta XMD boards help improve the durability, energy efficiency and overall lifespan of inverted roof systems. Whether used on new-build projects or refurbishment schemes, they provide reliable protection in demanding roofing environments while supporting compliance with modern building performance requirements.
Designed specifically for inverted roof vertical upstands, this system provides reliable protection and thermal performance in flat roofing applications. The XPS insulation board is ideal for safeguarding vulnerable roof edge details, including parapet walls, perimeter zones and vertical upstands that are exposed to weathering and mechanical impact. Suitable for both new build and refurbishment projects, it helps maintain the long-term integrity of inverted roofing systems while supporting efficient thermal insulation at critical junctions.
