Thermal insulation fastener FISCHER 562509 — pack of 100 for insulation fixing

FISCHER 562509 pack of 100 thermal insulation fasteners is a set designed for mechanical fixing of insulation boards and mats to substrate surfaces. Manufactured by FISCHER, these fasteners are intended for use in renovation and new-build projects where reliable anchoring and consistent spacing of insulation are required. The pack contains multiple identical fasteners that simplify installation and help ensure uniform fixation of external and internal insulation systems.

Advantages

These thermal insulation fasteners offer consistent holding power and are sized for repeatable, uniform anchoring. Their design allows quick placement and helps maintain the insulation layer flat against the substrate, reducing the risk of movement or gaps. Supplied in a pack of 100, the fasteners provide practical coverage for medium-scale insulation jobs and eliminate the need to source individual components. Compatibility with standard insulation boards and mats makes them suitable for a wide range of building applications.

Suitable for

• Fixing external thermal insulation composite systems (ETICS) to masonry or concrete
• Securing internal insulation boards and mineral wool mats
• Renovation projects requiring replacement or reinforcement of thermal insulation
• New construction where mechanical anchoring of insulation is specified

Key specifications

• Quantity: pack of 100 fasteners
• Application: mechanical anchoring of insulation boards and mats
• Compatibility: suitable for common insulation materials such as polystyrene, mineral wool and similar boards
• Use environment: designed for both external and internal insulation systems
• Function: provides consistent spacing and reliable hold for insulation layers

How to use

Drill pilot holes into the substrate at the locations specified by the insulation system design, taking into account the required spacing and edge distances. Insert the insulation fastener through the insulation board and into the predrilled hole, then secure according to the fastening method appropriate for the substrate until the insulation is held firmly but not excessively compressed. Repeat the process across the surface at regular intervals to achieve even support and prevent thermal bridging or air gaps.

Usage recommendations

Store the pack in a dry place away from direct sunlight. Select drill bit size and fastening pattern based on the substrate type and insulation manufacturer’s instructions. For external applications, combine mechanical fasteners with the recommended adhesive where specified by the insulation system to achieve the required wind-load resistance and thermal performance.
