In the drive towards more energy efficient buildings, the thermal performance of a building’s envelope can make a significant contribution to reducing the overall building energy usage. With the launch of The Best Practice Guide to External Wall Insulation (EWI), BRUFMA’s Chief Executive Chris Hall says designers, installers and their customers will be able to gain insight into External Wall Insulation as an effective way of reducing expensive and wasteful heat loss from both domestic or commercial buildings.
Endorsed by the UK’s leading PIR manufacturers, this comprehensive guide from The British Rigid Urethane Foam Manufacturer’s Association (BRUFMA) aims to promote best practice when designing and constructing a building that is to receive an External Wall Insulation render system which incorporates rigid PIR insulation boards.
EWI systems, also known as ETICS (External Thermal Insulation Composite Systems), are suitable for both new and old buildings and the key benefits of EWI render systems include improved aesthetics, improved energy performance and the extended serviceable life of a building.
EWI Systems offer benefits throughout the year, also acting as heat protection on hot summer days as well, helping to create a more comfortable indoor climate – often without the need for additional cooling.
Highly efficient PIR insulation products, produced by BRUFMA members, have been used in ETICS for a number of years now and it is hoped this agreed standard guidance will be of help to both designers and installers to ensure delivery of high quality ETICS systems. BRUFMA supports a system approach to ETICS and is pleased to develop this guide in support of the growing ETICS Industry in the UK.
There are many different types of EWI systems incorporating PIR insulation boards, featuring a multitude of finishes and methods of application. External Wall Insulation is often the logical choice for improving the thermal performance and external façade of an existing or new building, and is especially popular for high-rise buildings. In some cases an EWI system may be the only practical method of achieving significant thermal and aesthetic upgrades.
Building a solid case for energy efficiency starts with the building itself. Rather than being seduced by expensive and often unproven green technologies, the key is to get the fabric of the building as energy efficient as possible as this will make sustainability achievable in the long term.
