Certificate type
High-performance, lightweight external wall insulation (EWI) system based on low-lambda, enhanced expanded polystyrene insulation with PermaRock Brick Slip Finish.
Application
PermaRock EPS Premium EWI systems are suitable for use above damp-proof course (DPC) level on buildings of dense or no-fines concrete, brickwork, blockwork, or suitably sheathed light steel frame or timber frame buildings, in any geographical location including those classified as having very severe exposure to wind-driven rain.
PermaRock EPS Premium 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.
The systems can be used on new or existing buildings in both the residential and non-residential sectors.
PermaRock Mineral Fibre firebreaks should be incorporated into the system to meet the requirements of the Building Regulations.
PermaRock systems are only for installation by PermaRock registered installers.
Description
High-performance, lightweight external wall insulation (EWI) system based on enhanced expanded polystyrene (EPS) insulation that incorporates microscopic particles of graphite for enhanced thermal performance and to dissipate heat.
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 EPS Premium EWI system, the system achieves a B-s1-d0 classification and is suitable for use on buildings up to 11 m in height.
Features and benefits:
- Lightweight.
- For buildings up to 11 m in height.
- Suitable for all exposure conditions.
- High thermal performance insulation.
- PAS 2035 compliant.
- Insulation thickness 20–300 mm.
- Low air permeability. Can assist in improving airtightness.
- Adhesively bonded and mechanically fixed insulation.
- High wind load resistance.
- Thermal conductivity: 0.030 W/m·K.
- BRE Global Certification 158/12.
Design considerations:
- Thermal calculations can be carried out for each project to help to determine the thickness of insulation required to achieve U-value requirements.
Beads/ Trims/ Profiles:
- A full range of beads, trims, sealing tapes, expansion joint tapes and window sealing strips (APU beads) is available to complete the design of the system.
