Compliance with Standards
All works should comply with the relevant building regulations and this should be considered at the planning stage. Some works may require full planning permission, whilst others may require permissions from third parties to be carried out. In the planning phase it should be considered as to whether the works require planning permission, lawful consent, scaffolding licences or any other relevant permissions for the works to go ahead.
Whilst responsibility may be on the client with regards to permissions, it is good practice for an installer to make the client aware of all the relevant regulations and ensure that they are fully informed of these requirements before consenting to any works.
The substrate is the material on which the system is being installed, and the condition of the substrate and how it is prepared is crucial for a good installation.
The following substrates are suitable for installation of ETICS, though it is always good practice to verify the condition of the wall before application of the ETICS begins:
- Aerated concrete
- Cavity and solid breezeblock
- Lining concrete with cement bonded woodchip.
Where existing render is present, it is essential that these are appropriately tested and prepared in order for the ETICS to be installed correctly.
