The Mineral Wool Reinforcement Collar – 140mm is a large-format fibreglass-reinforced polymer disc used to improve mechanical fixing performance when securing mineral wool insulation boards. With a wide 140mm diameter, it provides increased surface contact, making it ideal for lamella and high-load zones such as building corners and exposed façades.

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.
