EXTERNAL WALL INSULATION / NEW BUILD /
LIGHTWEIGHT METAL FRAME CONSTRUCTIONS
Lightweight metal framing is used more and more frequently as a fast track construction method, bringing the quality control benefits of off-site, pre-fabrication to the construction site.
PermaRock has developed systems that meet the specific needs of this form of construction and systems are available with third party accreditation for application to metal frame construction.
Systems can be fixed to various types of exterior sheathing boards, with or without breather membranes, and systems can be designed to incorporate drained cavities to meet the specific requirements of NHBC, Zurich as well as other building insurers, or for direct application where cavities are not required.
Direct Fix System
PermaRock’s drained cavity Track-EPS system is fully tested for fire performance in accordance with BS 8414, Part 2, 2005 and meets the requirements set out in BR135 ‘Fire performance of external thermal insulation for walls of multi-storey buildings’, second edition, Annex B 2007.
