Insulation Anchor FISCHER FID-II/PLUS for EPS/XPS, single piece

FISCHER FID-II/PLUS insulation anchor is a single-piece fastener engineered for mechanical fixing of EPS and XPS insulation boards to underlying substrates. Intended for use in façade insulation systems, renovation and new construction, the anchor secures thermal insulation layers against wind loads and mechanical stress while maintaining thermal performance of the insulation system.

Advantages

The single-piece design simplifies installation by reducing component handling and alignment steps. The anchor provides reliable mechanical retention through the insulation layer into the substrate, ensuring stable fixation of EPS and XPS boards. Its geometry is optimized to limit thermal bridging and to maintain the integrity of the insulation surface. Compatibility with common façade substrates allows flexible use across renovation and new build projects.

Suitable for

• Fixing EPS (expanded polystyrene) insulation boards to façades
• Fixing XPS (extruded polystyrene) insulation boards to façades
• Mechanical fastening in external thermal insulation composite systems (ETICS)
• Renovation projects and new construction where wind loads and mechanical stress must be resisted

Key specifications

• Design: single-piece insulation anchor for EPS and XPS
• Function: mechanical fixing through insulation to the substrate
• Application area: façade insulation systems, external walls
• Material characteristics: designed to minimize thermal bridging (geometry-optimized)
• Performance: provides retention against wind loads and mechanical stress

How to use

Drill a hole through the insulation board to the required depth in the substrate, ensuring correct hole diameter and depth for the chosen anchor length. Insert the insulation anchor through the insulation and into the substrate, then drive or fix it according to the substrate type until the anchor head sits flush with the insulation surface. Follow manufacturer guidance for anchor spacing, embedment depth and fixing tools to achieve the required mechanical retention and thermal performance.

Usage recommendations

Use with correctly sized anchors and recommended drill diameters for the specific substrate. Combine mechanical fixing with adhesive bonding where specified by the insulation system design. Verify substrate condition and follow relevant codes for façade insulation installations to ensure long-term performance.
