EJOT UK provides fully tested standing seam fastening solution for new ‘civic hub’


E


JOT UK has supported roofi ng and cladding products distributor Tektum Supplies and contractor


Fowler McKenzie to develop a robust fi xing specifi cation for the building envelope of a highly sustainable new multi-purpose civic facility in Aberdeenshire.


The two-storey, £11.4million development in Ellon is designed to elevated sustainability standards to refl ect its signifi cance and to achieve net zero in operation. It incorporates renewable energy systems and a highly insulated and airtight envelope to minimise energy use.


A key challenge for the construction of the building envelope for ‘Formartine House’ was how best to securely fi x the Kalzip standing seam system to the building’s structure. This is formed of glulam beams and supporting secondary steelwork, with the envelope also featuring a thick layer of insulation as part of a design to Passivhaus standards.


To determine the most effective fi xing


solution for this unconventional envelope design, the project’s appointed roofi ng and cladding contractor,


consulted with Tektum Supplies, with whom EJOT UK has a strong working relationship.


The process started with Tektum utilising


their unique prognosis software to generate the calculations necessary, confi rming that the fasteners recommended by EJOT would satisfy Kalzip’s own technical criteria. Tektum’s calculation program has been developed specifi cally for specifi cations such as this, with the benefi t here of being able to provide EJOT’s technical team with the


Mike Saini, managing director of Tektum Supplies said:


“Collaboration with the Fowler McKenzie,


fastener manufacturer at an early stage is key to the success of projects like this and, through our work with the EJOT UK team on previous projects over many years, we knew they would have the products, resources and expertise to confi rm our own calculations.


“Combining our prognosis data with Applitec’s physical testing capabilities meant we could achieve a fastener specifi cation that everyone in the project could depend on. It enabled Fowler McKenzie to move forward with the envelope construction with complete


Pullout tests conducted by EJOT’s technical team confi rmed the suitability of the two recommended fasteners. They also looked deeper into the material characteristics of the proposed envelope build-up, including an analysis of the steel section using X-Ray Fluorescence (XRF) technology and withdrawal testing on the glulam sections which were conditioned in one of Applitec’s dedicated chambers for one week. Installation depth was also carefully monitored to further ensure quality control and consistency.


Jon Knaggs, technical manager for


Industrial Light Weight Construction at EJOT UK added: “When Tektum approached us for a standing seam fi xing solution we immediately recommended two types of our JT3 fastener. One of these, the FM Approved JT3-X2-6.0,


is actually purpose-designed


for fi xing standing seams and brackets back to steel and aluminium substructures, and has been used on projects where Kalzip is specifi ed, as well as other similar systems, for many years.”

confi dence, providing peace of mind for the main contractor and the client that the roof will perform as specifi ed.”
