Permarock Mineral Fibre EWI System with Brick Slip Finish - Class A External Wall Insulation System

High-performance mineral fibre external wall insulation (EWI) system comprising of non-combustible Euroclass A1 insulation, reinforced base coat and acrylic brick slip finish. The system achieves Euroclass A2-s1,d0 (EN 13501-1).

Permarock Mineral Fibre external wall insulation (EWI) systems are fire-safe, high-performance thermal insulation systems suitable for application to new or existing buildings including relevant buildings as defined in the Building Regulations. Systems are suitable for use at any height and in proximity to any boundary.

Permarock Mineral Fibre insulation is adhesively bonded and mechanically fixed and can be applied onto walls of dense or no-fines concrete, brickwork, blockwork, or suitably sheathed light steel frame or timber frame construction, in any geographical location including those classified as having very severe exposure to wind-driven rain.

Permarock Brick Slips are a lightweight, flexible and breathable synthetic resin tile used to replicate brick or stonework with the ability to create unique and interesting facade designs that are durable, robust and impact-resistant.

Manufactured from high-quality raw materials, Permarock Brick Slips are, as standard, supplied as facing and corner (pistol) brick slips in a range of 12 standard colours and 3 textures: Special colours, textures, sizes and shapes can be manufactured to order (minimum order quantities).

The Brick Slip Adhesive used to fix the slips is available in three standard colours (cement-grey, sandwhite and dark grey). The joints are pointed using Permarock Pointing Mortar (cement-grey) - other colours are available subject to minimum order quantities.

Permarock Brick Slips are assessed to EN 13501-1 and when used as the decorative finish of a Permarock Mineral Fibre EWI system, the system achieves an A2-s1-d0 classification and is suitable for use on buildings of any building height, including those with a storey height above 11 m, and in proximity to any boundary without restriction.

Features and benefits:

• Suitable for all 'Relevant Buildings' as defined in the Building Regulations, including residential buildings with a storey height above 11 m.
• Excellent fire performance: Non-combustible (Class A1) mineral (stone) fibre insulation - Fire breaks are not required.
• A2-s1,d0 reaction to fire classification (EN 13501-1).
• No restrictions on proximity to boundaries.
• Adhesively bonded and mechanically fixed insulation.
• High resistance to wind loads.
• Mechanically anchored reinforcement layer: Provides enhanced resistance to wind loading and additional structural stability in a fire.
• High impact resistance.
• Low embodied energy.
• Thermal conductivity: 0.036–0.039 W/m·K (depending on insulation specified).
• BRE Global Certificate No.158/12.
• Wide range of brick slip colours and textures available.
• Ecopoints score of 0.10 (m²) - 'Excellent' rating.
• Acoustic benefit over other insulant types.
• Has a working design life of in excess of 30 years.
• No restriction on brick slip colour. Here.

Design considerations:

• U-value calculations can be carried out for each project to determine the thickness of insulation required to achieve particular thermal performance requirements.
• For high-rise buildings, a wind load assessment should be carried out by a suitably qualified structural engineer and the results should be provided to Permarock to enable an optimised fixing arrangement to be provided.
• Contact Permarock to discuss your proposed design to enable us to assist you in specifying the correct system and component parts.
• Further information can be obtained from Permarock's Technical Hub

Beads and trims:

• A full range of beads, trims, profiles and seals is available to enable the system to be interfaced with other building elements.
