EJOT secures FM approval for single-ply flat roofing fasteners 22 July 2022

EJOT has added another significant quality standard to many of its flat roofing fastener and washer combinations by gaining approval from American testing institute, FM Global.

The internationally-recognised FM Approval on a significant number of EJOT single ply flat roofing products corresponds with, and complements, the company’s existing European Technical Approval (ETA), confirming the safety, reliability, and durability of the flat roofing product combinations.

Importantly, unlike the European assessments that focus on the individual product’s performance capabilities, the FM Approval process looks at the complete assembly by testing an entire roofing system – the fastener, substructure, insulation material and roof sheet.

The EJOT fastener and washer combinations tested include the EcoTek tube washer with FBS-R fastener, which is a popular choice for attaching membrane and insulation to concrete, as well as TKR/TKE fasteners with the HTK 2G 50 tube washer. This is typically used when attaching insulation and a single layer waterproof membrane to a steel or plywood deck.

Successfully passing the rigorous testing process in various roofing membrane combinations gives these fastener/washer combinations FM Approvals Standard 4470. This provides additional certification to support the products and maintain their worldwide use in the flat roofing market.

As a result, EJOT can present greater flexibility and security for OEMs globally, with design data being available not just within the ETA but from the FM Roofnav design database. “FM Approval adds another quality dimension to our most widely used single ply flat roofing fastener/washer combinations, confirming the standards we have already demonstrated in Europe and giving specifiers and OEMs across the globe a recognised seal of approval. FM Approval has become an increasingly important factor for investors and building owners throughout Europe who are demanding the American quality certificate, so it was only right that we as a responsible OEM that we responded to the market needs by gaining approval,” explains Kevin Rackley, product manager for membrane system fasteners at EJOT UK.

“It will also support the use of our products in international construction projects where FM approval can be a major factor, particularly where there is a requirement in the tendering process in order to comply with FM Global's insurance standards.”
