Soltherm Ultimate FSC EWI system is a BBA approved external wall insulation system, featuring a patented composite Grey Expanded Polystyrene (EPS) insulation board demonstrating exceptional fire performance vs. conventional EPS systems (Soltherm Fire Safe Composite Insulation).
Soltherm Ultimate FSC EWI system includes either thin coat silicone render or polymer modified dashing render with dashing aggregates finishes.
Soltherm Ultimate FSC EWI systems improved fire performance is achieved through three unique features that dramatically reduce fire spread through the EWI system:
A1 Fire Rated Compartmentalization:
A1 fire barriers that generate fire safe partitions within the insulation panel. These barriers prevent direct fire exposure inside the system and restrict the melted polystyrene from running down to the fire source and fueling the fire.
Innovative window & door head fire barriers:
The FSC EWI system requires that a specially modified mineral wool fire barrier is installed above all window and door heads. This pioneering fire barrier has been developed to prevent the absorption of melted polystyrene during the fire.
Mechanically & Adhesively fixed:
Composite panels are both mechanically and adhesively fixed. The insulation is adhered to the substrate with A1 rated Soltherm Adhesive. This adhesive prevents the movement of fire and toxic gases behind the system.
