Datacentre built with SIPitFR fire rated panels

1hr FIRE rated WALLS

SIPit‑FR is a high‑strength construction panel that combines structural frame, integrated insulation, and built‑in, 1‑hour fire protection, in one product. It is installed as a fire rated wall, fire rated roof, or fire rated floor, creating a fast, efficient, and compliant structural system.

BS EN 1365-1 CERTIFIED

The SIPit-FR is the only 1hr fire rated structural, insulated fire panel.  It has been through rigorous thermal resistance testing that confirmed over 60-minute fire integrity from both sides of the panel, internal and external, under extreme structural load-bearing capacity conditions. SIPit-FR panels meet the highest European safety standards for commercial and industrial applications. REI 60/60/60

SUSTAINABILITY & CARBON IMPACT

The high-performance PU core provides such extreme thermal efficiency that the SIPit-FR system saves 20–50× more CO₂ over its life cycle than was required for its manufacture. By combining this core with sustainably sourced CMC facings, we deliver a rapid structural solution that actively offsets embedded carbon throughout its operational lifespan.

The CMC board and advanced PU system are engineered for ultimate environmental performance, achieving a carbon-negative status within just 3 years of installation.
