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
