EJOT secures FM Approval for single-ply flat roofing fasteners

< 1 min

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.

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 fastener/washer combinations approved include the EcoTek tube-washer with FBS-R fastener—popular for attaching membrane and insulation to concrete—and TKR/TKE fasteners with the HTK 2G 50 tube-washer, typically used for attaching insulation and a single layer waterproof membrane to a steel or plywood deck.

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

This means EJOT can present greater flexibility and security for OEMs globally, with design data available in the FM Roofnav design database ( as well as within the ETA.
