EXTERNAL WALL INSULATION / REFURBISHMENT /
LOW-RISE BUILDINGS /
Solid or cavity wall. Concrete, timber or steel frame. Houses, bungalows or flats. Traditional or nontraditional build. PermaRock offers complete technical solutions to meet the external wall insulation requirements of all forms of low-rise housing.
With traditional solid wall or cavity wall construction, PermaRock systems can provide all levels of rejuvenation from a simple aesthetic uplift, using a high performance exterior render system, to full thermal performance improvements, elimination of cold bridging and condensation using a fully accredited external wall insulation system (EWI).
A PermaRock EWI system provides immediate benefits in terms of heat loss reductions and savings in heat energy costs. The system protects the building fabric, extending the useful life of the structure, and offers the opportunity for improving the appearance using any of our range of low maintenance exterior finishes and effects.
PermaRock systems can be designed to deliver U-values that are considerably better than current Building Regulations requirements, and systems can be designed for application to walls that have already been treated with cavity insulation, to provide further improvements in thermal performance whilst shifting the structural dewpoint to the outside, thereby eliminating the risk of interstitial condensation.
