Insulation fastener FISCHER 562515 — pack of 100 for thermal insulation systems

FISCHER 562515 is a pack of 100 insulation fasteners designed for use in external thermal insulation composite systems (ETICS) and internal insulation installations. The TermoFix CN fastener is a hammer-set anchoring solution that secures compression-resistant insulation boards—polystyrene (EPS/XPS), mineral wool or wood-fibre insulation—up to 200 mm thick to solid and perforated masonry or concrete substrates. The fastener combines a one-piece plastic sleeve with a separate steel nail: the plastic overmould provides thermal separation while the steel component delivers the required load-bearing capacity. The product is intended for repeatable, mechanical fixing where a reliable connection between insulation and backing structure is required.

Advantages

The TermoFix CN design provides thermal isolation at the fixing point due to its overmoulded plastic component while maintaining high pull-out and shear performance through a steel nail. Supplied in a pack of 100, these fasteners allow efficient, consistent installation across façade or interior insulation projects. The hammer-set application requires no special tools beyond a standard hammer, enabling quick installation and straightforward handling on site. The fastener is approved for use in building material classes A, B and C and is suitable for common masonry and concrete substrates.

Suitable for

• Fixing compression-resistant insulation boards up to 200 mm thick
• External ETICS façades and internal insulation systems
• Polystyrene (EPS/XPS), mineral wool and wood-fibre insulation
• Solid and perforated masonry, concrete and common building substrates

Key specifications

• Packaging quantity: 100 fasteners per pack
• Application method: hammer-set mechanical fixing
• Suitable insulation thickness: up to 200 mm
• Compatible insulation types: polystyrene, mineral wool, wood-fibre
• Component materials: plastic sleeve with steel nail for load-bearing
• Approved for use in common building material classes (A, B, C)

How to use

Select the appropriate drilling diameter and embedment depth according to the substrate and insulation thickness. Drill a clearance hole through the insulation into the substrate to the required depth, clean the hole of dust, and insert the fastener sleeve flush with the insulation surface. Position the separate steel nail and drive it in with a hammer until the sleeve and plate are securely seated against the insulation. Ensure each fastener is installed perpendicular to the façade and avoid overdriving, which can damage the insulation or reduce load capacity. Follow applicable local regulations and system manufacturer instructions for spacing and pattern of fixings.

Usage recommendations

Use TermoFix CN fasteners in combination with the ETICS system components recommended by the insulation or façade manufacturer. Verify substrate condition and load requirements before installation, and perform pull-out tests where project specifications require. Store packs in a dry place and protect from prolonged UV exposure prior to installation.
