EXTERNAL WALL INSULATION SYSTEMS /
TRACK-EPS Drained Cavity System
The PermaRock Track-EPS system is a high performance, low density EWI composite system, based on expanded polystyrene insulating panels which are pre-aged and flame retardant.
The system employs a rail or track fixing mechanism to secure the insulation panels to the substrate. This approach enables the creation of a drained cavity space behind the insulation panels to meet the specific requirements of NHBC and Zurich Insurance for insulated render system applications to timber and metal frame constructions. In addition, the use of rail mounting enables façades to be created that are truly plumb and flat, overcoming deficiencies in irregular or uneven backgrounds.
PermaRock Track Systems offer a number of key advantages:
- Low thermal conductivity insulation materials (Lambda = 0.040 W/mK).
- True surface flatness can be achieved.
- Suitable for solid or cavity walls, timber or metal frame buildings.
- NHBC/Zurich compliant drained cavities can be created on timber or metal frame constructions.
- Low environmental impact: CFC/HCFC Free and Zero ODP.
- Can be applied to uneven surfaces
The PermaRock Track-EPS Drained Cavity System has been tested in accordance with BS 8414-2: 2005 Fire performance of external cladding systems – Part 2: test method for non-loadbearing external cladding systems fixed to and supported by a structural steel frame and is assessed in accordance with BR 135 ‘Fire performance of external thermal insulation for walls of multi-storey buildings’, Second Edition 2003. The system complies with the requirements of BR 135 for multi-storey buildings.
