High-performance, lightweight external wall insulation (EWI) system based on low-lambda, enhanced expanded polystyrene insulation with PermaRock SiliconeUltra K Finish.
Application
Suited for the upgrade of existing buildings and for new buildings, particularly where exemplar levels of thermal performance are required.
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 EPS-Premium insulation contains a flame-retardant additive (FRA) for improved fire resistance performance.
Permarock SiliconeUltra K Finish is a high-performance exterior through-colour textured render based on a hybrid binder system of organically crosslinked nano-quartz particles and silicone emulsion. It is a lightweight, water-repellent finish with excellent water vapour permeability and incorporates photo-catalytic particles which actively break down dirt particles enabling them to be washed from the surface under normal weathering. PermaRock SiliconeUltra K-Finish resists aggressive air-borne pollutants, provides enhanced resistance to dirt pick-up and contains a preservative against coating deterioration due to algae and fungus.
Features and benefits:
- Lightweight.
- Suitable for all buildings up to 11 m in height.
- Suitable for all exposure conditions.
- High thermal performance insulation.
- PAS 2035 compliant.
- Insulation thickness 20 - 300 mm.
- PermaRock SiliconeUltra K-Finish is available in a range of over 500 colour shades with the highest binder stability (Class A resistance to chalking) and colour retention (Group 1 light fastness/colour stability).
- 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.
- Permarock Mineral Fibre Insulation fire breaks should be incorporated into the system at appropriate locations.
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.
