🔩 ejotherm STR H Screw Anchor fastening plugs – Secure Fixing for Wood Fiber Insulation
The ejotherm STR H screw anchor is the perfect solution for securely mounting external thermal insulation composite systems (ETICS/WDVS) on wood and metal substrates. Whether you need a flush or recessed installation, this fastening system is especially well-suited for wood fiber insulation boards – such as Steico protect or Steico facade – in both new builds and energy-efficient renovation projects.
Designed with a galvanized steel screw and a thermally optimized expanded polystyrene (EPS) plate with sealing plug, this fastener ensures long-lasting, secure anchoring without creating thermal bridges. That makes it the ideal choice for combining with natural wood fiber insulation materials.
