External Wall insulation Morden London
There are several key considerations when specifying ETICS for a property: energy performance, thermal insulation, safety and durability, to name a few. It is important that a prospective application considers the various components of the system and this requires highly professional planning as well as execution.
Insulation such as this is designed to both protect the building from the elements, provide thermal insulation, and also in many instances reduce the occurrence of certain types of damp. It will not improve air tightness in most cases.
Composition of an ETICS system
A properly specified system should include the following components: adhesive; insulation, mechanical fixings (where necessary), base coat, reinforcement mesh, primer and top coat. Depending on the job, there are also likely to be numerous beading products, starter tracks, trims and expansion joints, although this can vary from installation to installation.
As per British Board of Agrement requirements, all parts of this system need to be approved for use, and only a whole system will meet the regulations – that is, you cannot mix and match two different systems to meet the BBA requirements.
Installers are therefore required to ensure that all the products they use are compatible for the system being installed. The BBA certificate for a certain product should be available to view on the BBA website and you can ask your installer to provide this if you are in any doubt as to the components of the system being installed.
