Marmox Metallic Washers
Marmox Metallic Washers
Marmox Metallic Washers are premium galvanized steel fixing washers specifically engineered for the secure mechanical attachment of Marmox Insulation and Backer Boards to timber framing, masonry, and stud wall systems.
Technical Property | Official Certified Value | Engineering Benefit |
Material Base | High-grade galvanized steel | Exceptional corrosion resistance in high-moisture and wet room environments |
Geometric Profile | Perforated concave disc with center screw hole | Sinks flush with the board surface for seamless tile installation |
Mechanical Anchorage | Compatible with wood, masonry, and drywall screws | Distributes fixing stress evenly to prevent board surface damage |
Adhesive Keying | Multi-perforated surface pattern | Allows cementitious mortar to bond directly through the washer |
Prevents Board Damage: Spreads mechanical clamping load, preventing screw heads from penetrating the insulation core.
Corrosion Resistant: Galvanized finish protects against rust formation in wet areas and humid bathrooms.
Flush Surface Profile: Counter-sunk design ensures a level, flat surface ready for waterproofing and tiling.
Enhanced Adhesive Bonding: Perforations allow tile adhesive to key firmly over the fixing point.
Fast & Reliable Installation: Easy to drive into position using standard mechanical fasteners and drivers.
Marmox Board Mechanical Fixings: Securing backer boards to walls, ceilings, and timber or metal studwork.
Floor & Wall Board Assemblies: Secondary mechanical anchoring for insulation panels on masonry and concrete substrates.
Wet Room & Shower Substructures: Fixing waterproof backer boards securely before tile or mosaic application.
Over-Boarding & Insulation Systems: Securing thermal and waterproof insulation panels in residential and commercial builds.
Fixing Layout: Position Marmox Metallic Washers along the board edges and center according to technical spacing standards (typically 30-40 cm centers).
Screw Insertion: Insert the designated wood or masonry screw into the central recess of the washer.
Fastening: Drive the screw into the substrate until the washer sits completely flush with the Marmox board surface.
Sealing & Tiling: Cover the washer head with sealing tape or tile adhesive during the tiling process to ensure full surface continuity.
