Knauf Insulation Ekoboard 039 mineral wool slabs

Knauf Insulation Ekoboard 039 are general-purpose glass mineral wool slabs for thermal and sound insulation in structures where the insulation carries no mechanical load. They are made with ECOSE® Technology – a bio-based binder with no added formaldehyde or artificial colours – so the slabs are softer to handle, less dusty and odourless.
