Phenolic External Wall Insulation Systems

PermaRock Phenolic external wall insulation systems incorporate high performance rigid thermoset phenolic foam insulation boards. This lightweight, low thermal conductivity insulation enables high levels of thermal performance to be achieved utilising thinner sections of insulation.

These systems are an ideal solution for buildings that cannot increase their footprint significantly due to encroachment onto pavements, passageways, proximity to adjacent properties, or which are located within conservation areas.

Key Features

BRE Global Certification
BIM Level 2 compliant
Higher levels of thermal performance for thinner levels of insulation

Approvals	BRE Global Certification: BRE Certificate No. 158/12
Thermal Performance	Systems can be designed to achieve U-values which satisfy or exceed current UK Building Regulation requirements.
Weather Resistance	Provides a weather resistant cladding to new and existing backing walls of brick and block masonry, dense and no-fines concrete and sheathed light gauge steel frame and timber frame constructions. Can be designed buildings in locations where the wind driven rain exposure classification is very severe.
Wind Loads	Using a combination of adhesive bonding and mechanical fixing, these systems can be designed to withstand all anticipated wind load (suction) scenarios in the UK.
Impact Resistance	Systems can achieve levels of hard body impact resistance in excess of 40J and can be designed for the zones associated with Categories I, II and III as defined in ETAG004.
Fire Performance	Class O surfaces as defined in the Building Regulations when tested to BS 476 parts 6 and 7 can be achieved.
Water Vapour Permeability	The systems are water vapour permeable. The rate of permeability depends on the system (thickness and decorative finish type) selected.
Design Life	Systems can be considered to have a design working like of at least 30 years. Lifetimes significantly in excess of 30 years can be achieved with proper maintenance and repair if damaged.
