Thermal insulation fastener FISCHER 562514 — pack of 100 for insulating systems

FISCHER 562514 — pack of 100 thermal insulation fasteners (TermoFix CN) provides a mechanical fixing solution for external thermal insulation composite systems (ETICS). Each pack contains 100 hammer-set fasteners designed to secure compression-resistant insulation boards such as expanded polystyrene (EPS), mineral wool and wood fibre insulation up to 200 mm thickness to solid and perforated substrates. The fastener is a one-piece plastic sleeve with an integrated plate and an enclosed compound nail combining an overmoulded plastic part for thermal separation and a steel component for structural load-bearing. The TermoFix CN is driven in with a hammer and is approved for use with building material classes A, B and C.

Advantages

The TermoFix CN fastener combines thermal performance and mechanical strength: an overmoulded plastic nail section reduces thermal bridging while the steel core provides reliable load capacity. Its one-piece sleeve with plate element simplifies installation and minimizes the number of components to handle on site. Supplied in packs of 100, the fasteners are suitable for larger installation runs and reduce the need for individual packaging during work. Hammer-set application eliminates the need for powered tools for driving the nail, enabling quick fixes and lower equipment demands.

Suitable for

• Fixing EPS (expanded polystyrene) insulation boards to façades and internal partitions
• Securing mineral wool insulation in ETICS applications
• Mounting wood fibre insulation up to 200 mm thickness
• Mechanical fixing to solid and perforated masonry or concrete substrates
• Jobs where thermal isolation of the fixings is required to reduce thermal bridging

Key specifications

• Pack quantity: 100 pieces per pack
• Type: hammer-set ETICS insulation fastener (TermoFix CN)
• Compatible insulation thickness: up to 200 mm
• Material composition: plastic sleeve with plate element and compound nail (plastic overmould + steel core)
• Approved for use with building material classes: A, B and C
• Intended substrates: solid and perforated masonry, concrete and similar building materials
• Installation method: driven in with a hammer (mechanical fixing)

How to use

Position the insulation board on the prepared substrate and mark fixing points according to the project specification or manufacturer guidance. Align the TermoFix CN sleeve with plate over the marked point and drive the compound nail into the substrate using a suitable hammer until the plate sits flush with the insulation surface. Ensure the sleeve is fully engaged into the substrate to achieve specified load-bearing performance. If working with perforated or lightweight substrates, follow project-specific guidance for fixing spacing and additional adhesives or anchors as required. Check local regulations and ETICS system instructions for recommended fixing patterns and edge distances.

Usage recommendations

For reliable performance, combine mechanical fixing with appropriate adhesive where specified by the ETICS system manufacturer. Allow sufficient spacing and the correct number of fasteners per square metre depending on wind load and substrate condition. Store packs dry and protect from prolonged UV exposure prior to installation. Use protective eyewear and follow safe hammering practices during installation.
