Mineral Wool Reinforcement Collar – 140 mm (TDXP-140) is a large-format glass-fibre-reinforced polyethylene  disc that improves the performance of mechanical fixings when securing mineral wool insulation boards. The wide 140 mm diameter increases surface contact and distributes load, making it ideal for lamella insulation and high-load areas such as building corners and exposed façades. Compatible with ETICS/MW systems and designed to reduce fixing imprint and pull-through risk for a smoother, more durable façade.

Suitable Insulation Boards

Compatible Fixings

Provides additional fixing stability in high-wind and fire-break areas on mineral wool façades.

Key Features

• Large 140mm diameter for maximum load spread.
• Fibreglass-reinforced for rigidity and impact resistance.
• Ideal for lamella boards and high-load zones.
• Improves pull-through resistance and fixing durability.
• Works with hammer-in and screw fixings.
• Lightweight, easy to position, and durable.

Application

Preparation

• Confirm mineral wool insulation is installed flat and bonded correctly.
• Use in areas requiring reinforced fixing support (wind load or firebreak zones).

Installation steps

1. Position the collar on the board surface at the fixing location.
2. Insert mechanical fixing through centre opening.
3. Install fixing until collar sits flush with insulation.
4. Repeat according to system fixing layout.

Quality checks

• Ensure collars sit level without board deformation.
• Verify firm fixing hold and even pressure distribution.
