The 10mm Hammer Fixing with Plastic Pin is a mechanical fixing for external wall insulation (EWI) systems. It combines a durable polyethylene body with a fibreglass-reinforced pin for high impact resistance during installation. The telescopic sleeve ensures the washer sits flush with the insulation, reducing thermal bridging and improving system performance. It’s designed to transfer wind loads and provide long-term stability.

Suitable Insulation Boards

Compatible Substrates (ETA Categories A–E)

If the substrate condition is uncertain, carry out a pull-out test to confirm suitability.

Key Features

• Fibreglass-reinforced pin minimises breakage when hammered.

• Telescopic sleeve ensures correct embedment and a flush washer finish.

• Washer with adhesive pockets to improve bond with basecoat.

• Designed to resist wind suction forces in ETICS/EWI systems.

• ETA-15/0373 assessed.

• Fast, reliable installation.

Sizes & Box Quantities

Select length to suit insulation thickness + adhesive layer + required embedment depth.

Application

Preparation

• Mark out the fixing grid to suit the system design and wind-load zone.

• Check for hidden services (cables/pipework) before drilling.

• Select the correct drilling mode for the substrate: use rotary-only for aerated/voided blocks; use hammer mode for dense concrete/brick as appropriate.

Installation steps

1. Apply adhesive to the boards per your EWI specification and place boards tightly with staggered joints.

2. Drill perpendicular through the board into the substrate using the selected drilling mode.

3. Insert the fixing body and then drive the pin until seated. Do not over-drive or dish the board surface.

4. Install the specified number of fixings per board, paying particular attention to corners, reveals and high-suction zones.

5. Once all boards are fixed, proceed with basecoat and reinforcement mesh according to the system specification.

Fixing pattern & density

• Follow the project design; as a guide, many façades use 4–6 fixings per m², with additional fixings around openings and building corners.

• Keep consistent edge distances and avoid placing fixings too close to board edges or through board-to-board joints unless specified.

Quality checks

• Periodically verify pull-out resistance on-site where substrate variability is suspected.

• Replace any fixings that spin freely or fail to grip, and re-drill if necessary.
