Fixing solution for externally insulated walls

ETA-approved EJOT Iso-Corner provides assured fixing solution for externally insulated walls

EJOT has secured ETA (European Technical Assessment) approval for its Iso-Corner load-bearing bracket, an engineered fastening element for medium to heavy weight building elements – planned or unplanned – in ETICS and other external wall insulation applications.

The newly awarded ETA confirms the engineered value of EJOT Iso-Corner which is moulded from high density polyurethane foam and can be easily cut on site with an electric saw to sit flush with the external insulation face. This combination of structural strength and adaptability provides a dependable supporting bracket option offering a cantilever arm to length of between 80mm and 300mm.
It is ideally suited to specifiers and installers who need to attach building elements to a façade that is to be treated with an ETICS – external thermal insulation composite systems – or other external wall insulation solution. These could include elements such as railings and Juliet balconies, which require a secure attachment to the load-bearing external wall, the substrate.
Consider the make-up of an external wall insulation system. The insulation is typically attached to the wall structure, treated with coatings and mesh, and finished in the chosen render, brick-slips or other external treatment. The main depth of the system is the insulation board, and whilst this should generally be very securely fixed to the building substrate, it will not have the necessary structural strength to allow for load bearing attachments.
Any attempt to achieve a secure fix by driving through to the original building substrate could compromise the thermal insulation level. Unless a fixing is used that incorporates insulating materials as part of its design, the thermal barrier will be broken, and cold bridging will result. This is one of the criteria of PAS 2035, where it needs to be demonstrated that any cold bridging effects have been designed out of the chosen energy efficiency measure.
Iso-Corner is part of a range of ETICS mounting elements from EJOT designed to achieve safe, secure and long-term fastening solutions in refurbishment projects, including:

•  Iso-Spiral Anchor, a spiral-shaped plastic assembly anchor complete with sealing washer and integrated threaded sleeve which provides a fastening solution for lightweight elements in ETICS facades, such as house numbers and external lights.
•  Iso-Dart – a fastening system comprising of a façade anchor with plastic installation bush, complete with sealing washer, which accepts common coarse threaded screws for securely attaching light to medium loads.
•  Iso-Bloc – an easy-to-cut block moulded from high density EPS, which is particularly suitable as a backing to allow for thermal bridge-free attachments in ETICS applications.

As a global leader in construction fastening solutions, the EJOT UK team offers a wealth of technical support and specialist guidance to specifiers and installers to ensure they achieve the right result when mounting to ETICS facades.
