Insulation Anchor ELEKTROPLAST SM-50/EPN*P4 for Fixing Expanded Polystyrene (EPS)

Mechanical insulation anchor ELEKTROPLAST SM-50/EPN*P4 for Fixing Expanded Polystyrene (EPS) is engineered to provide stable mechanical fastening of EPS insulation boards to building substrates. Designed for use in external thermal insulation composite systems (ETICS) and façade insulation applications, this anchor complements adhesive systems and render layers to secure insulation over the long term while maintaining alignment and contact between insulation and substrate.

Advantages

The anchor offers reliable mechanical retention and resistance to pull-out when correctly installed into suitable substrates. Its geometry and materials are chosen for compatibility with expanded polystyrene, ensuring low thermal bridging and minimal disturbance of insulation continuity. The design allows rapid installation with common tools and helps maintain the flush position of boards prior to and during render application.

Suitable for

• Fixing expanded polystyrene (EPS) insulation boards in ETICS façades
• Supplementing adhesive fixation on external wall insulation
• Securing insulation on masonry, concrete, and similar base substrates
• Applications requiring long-term mechanical anchoring under render systems

Key specifications

• Intended for use with expanded polystyrene (EPS) insulation boards
• Mechanical anchor type suitable for external thermal insulation systems
• Designed to minimize thermal bridging at the fixing point
• Compatible with adhesive and render layers in façade systems
• Suitable for installation into common building substrates such as masonry and concrete

How to use

Mark the positions for anchors on the EPS board according to the insulation system layout and project specifications. Drill a pilot hole through the insulation down to the substrate using appropriate diameter and depth for the anchor and substrate. Insert the anchor through the EPS board, seat it against the substrate and activate the fixing method recommended for the substrate type (for example, expansion in masonry or fastening with appropriate plugs/anchors). Ensure the EPS board is held flush against the wall while anchors are set. After mechanical fixings are in place, proceed with basecoat and render application as specified by the ETICS manufacturer.

Usage recommendations

Use anchors at spacing and pattern prescribed by project specifications or applicable standards. Verify substrate condition and drill depth before installation. Combine mechanical anchors with the appropriate adhesive and render specified for the ETICS to achieve the intended thermal and mechanical performance. Follow local building codes and manufacturer guidance for drill bit selection and installation torque where relevant.

ELEKTROPLAST insulation anchors are intended to be used by trained installers experienced with external insulation systems. Selecting the correct anchor spacing, embedment depth and installation technique is essential to ensure system durability and thermal performance.
