External Wall Insulation for Existing Buildings

PermaRock Products Ltd, the longest established UK owned manufacturer and supplier of external wall insulation (EWI) systems, has 30 years experience of supplying EWI to the energy efficiency sector in the United Kingdom.

Many older buildings in the UK were built without any form of insulation in the walls and with ever increasing fuel bills, reducing heat energy losses through the external envelope and eliminating problems associated with condensation and dampness are important concerns for occupiers and owners of residential, public and commercial buildings.

External wall insulation (also referred to as solid wall insulation) is an ideal solution to help tackle these issues and is a technology that improves the energy performance of buildings by the application of insulation and a low maintenance decorative finish to the external wall surface.

High levels of energy efficiency can be achieved over other forms of insulation resulting in savings on energy bills. An average semi-detached home could typically save £260 per year on fuel costs (Source: Energy Savings Trust) through the installation of an external wall insulation system.

PermaRock’s EWI systems have been developed to suit the requirements of the UK market in terms of technical performance and application techniques. Our systems are UKAS accredited and fully compliant to the Green Deal Code of Practice and PAS 2030 for use under the Green Deal and the Energy Company Obligation (ECO) energy efficiency initiatives.

PermaRock systems have been designed for use on high and low rise buildings, for traditional and non-traditional forms of construction, including, solid wall or cavity wall, dense and no-fines concrete, brick, stone and metal, tile or timber clad structures.

Aesthetically and technically, we provide the latest innovations in render technology to enable buildings to be visually uplifted and systems are available in differing types and thicknesses of insulation to suit project specific requirements.

With over 30 years’ experience in the new build and retrofit markets, PermaRock’s product design data is compliant with Level 2 BIM (Building Information Modelling) and is available online at the NBS National BIM Library.

Six of PermaRock’s external wall insulation and exterior render systems are available as BIM objects:-

  • PermaRock Mineral Fibre EWI System
  • PermaRock EPS-Premium (Grey) EWI System
  • PermaRock Phenolic EWI System
  • PermaRock Track-EPS (Rail) EWI System
  • PermaRend Exterior Render System
  • PermaRock Exterior Render (Rainscreen) System

Technical Director at PermaRock Products Ltd, Dr Jeremy Richings explains, “Now that all government construction projects in the UK are required to be delivered within a BIM environment, PermaRock wanted to invest in creating BIM objects to enable it to stay ahead of the game.”

Dr Richings summed up the initiative by saying, “Public sector construction contracts such as schools and healthcare schemes form a substantial part of our business. Consequently PermaRock wanted to ensure that when a project is being developed and specified, the project designers and contractors engaged in delivering the project are able to access all the technical information relating to our products and can specify them with ease and confidence. Furthermore, as BIM has gained a foothold outside of central government, an increasing number of designers are engaging in the collaborative working process that BIM affords and we see the adoption of BIM as a way of driving up quality as well as reducing time, waste and duplication.”

PermaRock is one of the UK’s leading external wall insulation exterior render system suppliers and the company’s extensive experience includes working with local authorities, housing association registered providers, architects and contractors on refurbishment and new build projects across the UK.
