ETICS Installers in the UK
Whilst there are many installers across the UK, customers should only look to install EWI with companies that are approved installers. Quality installers will be approved via PAS 2030 with an accreditation body such as the BBA or NAPIT. Furthermore, the installer should be an accredited installer of the system in question being installed. That is, they must have been carded with the system designer and deemed competent to install the system.
Installers that fall outside these categories should be avoided as they will not be able to offer industry-backed warranties or prove that they are competent installers of the system. Their work is also not subject to regular inspection through an accreditation scheme.
- Storage – When storing materials at the building site in question, the instructions for the storage of each component must be considered. Adhesive needs to be kept dry for example, whilst exposure to extreme direct heat can cause melting of polystyrene. Follow the storage instructions of the manufacturer carefully.
- Weather Conditions – The weather can be unpredictable, but many aspects of a render system are unsuitable for installation at certain temperatures or in wet weather. A good installer will look at the time of year and the forecast to determine when each stage of the installation should be planned to take place. Most renders need to be applied in temperatures of 5 degrees or above for example, whilst temperatures higher than 30 degrees can make the render to dry too quickly, causing cracking and other defects. Good preparation can account for this – shading for example, to reduce the temperature of the wall, and protection from the rain to ensure works are not delayed by wet weather.
