Retrofit Installer Auditing

Evolusion are currently engaged by NSAI to carry out audits of Approved Installers of External Thermal Insulating Composite Systems (ETICS) and Cavity Wall Insulation (CWI) Systems countrywide.

External Thermal Insulating Composite Systems (ETICS)

 

Most commonly known as External Thermal Insulating Composite Systems (ETICS), but also referred to as External Wall Insulation (EWI), or External Insulating Finishing Systems (EIFS), external insulation involves fixing insulating materials such as expanded polystyrene slabs or mineral wool to the outer surface of the walls of a house, usually with a special adhesive and metal or plastic fixings.  A base coat embedded with a reinforcing fiberglass mesh to enhance impact resistance is applied to this insulation, and this is then covered with a final finishing render to provide weather resistance.

There are currently a number of different external insulation systems being marketed throughout Ireland. It is important that the system used is an approved system and that the installer is an approved installer.

Cavity Wall Insulation Systems

 

If the wall of a building comprises two parallel leaves of masonry construction, the wall may be suitable for retrofitting cavity insulation. This is achieved by drilling evenly spaced holes in the outer leaf and pumping fibre or bead insulation into the void. The holes in the masonry are then refilled and finished. Again, there are a number of cavity wall insulation systems on the market, and it is important to ensure that a certified system is installed by an NSAI Approved Installer.



Evolusion Innovation currently provide auditing services to the NSAI, whereby the documentation, records, and site installation work are inspected by our auditors on behalf of NSAI



Similar auditing/inspection services may be available to you depending on your needs and circumstances.
