RAWLPLUG mineral wool plug 63 mm R-TFIX-CAP63-MW for thermal insulation systems

RAWLPLUG mineral wool plug 63 mm R-TFIX-CAP63-MW is a mechanical fastener designed specifically for use with mineral wool insulation in external and internal thermal insulation systems. The plug is intended to secure mineral wool boards by providing a stable anchor point that supports insulation layers and helps maintain the integrity of the system under normal building conditions. Its 63 mm length is suited to common insulation thicknesses and typical substrate depths encountered in renovation and new-build projects.

Advantages

The plug is designed for compatibility with mineral wool, offering reliable mechanical fixation without damaging the insulation material. It provides consistent embedment and anchorage in common substrates used with external thermal insulation systems, contributing to long-term stability of installed insulation. The simple design reduces installation complexity and helps achieve uniform fixing patterns across insulation surfaces.

Suitable for

• Mechanical fastening of mineral wool boards in external thermal insulation composite systems (ETICS)
• Renovation and retrofit projects requiring added mechanical anchors for insulation
• New construction where mineral wool insulation is specified
• Applications where a 63 mm plug length matches insulation thickness and substrate depth

Key specifications

• Designed for mineral wool insulation
• 63 mm overall length suitable for typical insulation thicknesses
• Mechanical fixation type for thermal insulation systems
• Compatibility with common masonry and concrete substrates when used with appropriate anchors

How to use

Drill a hole through the insulation and into the substrate to the recommended depth for the chosen anchor system and ensure the hole diameter matches the plug specifications. Insert the plug through the mineral wool until the cap is flush with the insulation surface, then fit the appropriate anchor or screw to expand or secure the plug in the substrate according to the anchor manufacturer's instructions. Verify that the insulation board is held firmly and that fixings are evenly distributed to prevent movement.

Usage recommendations

Use with anchors and screws recommended for mineral wool systems and follow the guidance of the thermal insulation system manufacturer. Check substrate condition and drilling depth before installation. For best results, combine mechanical fixing with the adhesive and finishing layers specified in the insulation system design.
