Exterior wall / Facade

Description & Details

OmniFit® Slab 32 is a glass mineral wool slab, designed primarily for use as the inner leaf insulation between light steel frame studwork in a rainscreen façade system or in a steel frame construction with masonry outer leaf. It offers the best thermal conductivity of 0.032 W/mK in our range, combined with acoustic performance. OmniFit® Slab 32 is non-combustible with the best possible Euroclass A1 reaction to fire classification, and is manufactured using our unique bio-based binder, ECOSE® Technology.
