FusionX 
FUSIONX Overview
FUSIONX™ is a fully tested non-combustible walling solution which we developed in response to Building Regulation changes. Approved by the NHBC, FusionX™ holds LABC Warranty and is BOPAS accredited. This loadbearing external walling system is SCI and NHBC certified up to 10 storeys and can form part of a structure up to 14 storeys.
Fire
Enhancing onsite productivity through maximised Pre-Manufactured Value (PMV), FusionX™ is factory assembled for fast, cost-effective and quality-assured construction. FusionX™ has been tested thoroughly as an integrated system for thermal performance with fire resistance durations of 60, 90 and 120 minutes predictably achievable.
Thermal
Precision manufactured for rapid installation, FusionX™ can achieve U-values of 0.20W/m2k. The system provides developers and investors with a solution that offers a better strength to weight ratio than concrete, minimising groundworks and aiding sustainability outputs.*

Commercial
Commercial benefits include easier installation, enhanced on-site productivity and increased construction speed. FusionX™ is designed to be durable with a dimensionally stable material – steel has no risk of shrinkage, rotting, warping or cracking, and it does not expand or contract with moisture content. It is also renowned for being highly sustainable.
