Description
Top• EWI Slab is a consistent density, high strength, rock mineral wool slab with a water-repellent additive specifically designed for use in external wall insulation systems. It is dimensioned to be easy to handle and fix to a substrate.
• Krimpact™ technology realigns the mineral wool fibres during manufacture to increase impact strength without dramatically reducing thermal performance, making an ideal product for use behind a render finish.
• Furthermore, Krimpact™ technology achieves a consistent density slab. This ensures better long-term compressive strength, high impact resistance, better thermal performance and a thinner, lighter product compared to other high-strength insulation options.

Application EWI Slab is specifically for use with external wall insulation systems. The slabs can be either adhered and mechanically fixed or just mechanically fixed to the substrate then overlaid with a mesh and render system to the designers/system suppliers specification.
The slabs offer a solid and robust supporting substrate for the render and no fire stops are required.
Standards EWI Slab is made from non-combustible inorganic rock wool, defined as mineral wool in BS 3533: 1981 and is manufactured in accordance with BSI Quality Assurance Standard BS EN ISO 9001: 2000.
