Insulation Discs – Zinc-Plated – Secure Fixing

Product Overview

These zinc-plated insulation discs, with an 85mm diameter, are designed for securely fastening insulation materials to substrates. Ideal for applications requiring a broad, stable bearing surface, these discs ensure even load distribution, preventing insulation compression and maintaining thermal integrity.

The zinc-plated steel construction enhances corrosion resistance, offering long-term performance in both internal and sheltered external environments. Compatible with mechanical or screw fixings, these discs provide secure retention and consistent surface contact for both rigid and quilt insulation materials.

Features & Benefits

• Broad Contact Surface: Even pressure distribution reduces the risk of insulation damage during installation.
• Zinc-Plated Finish: Provides protection against corrosion, suitable for damp or humid conditions.
• Rigid Steel Construction: Ensures stable retention without deformation under load.
• Versatile Compatibility: Suitable for use with screw fixings, nail fixings, or insulation anchors.
• Secure Insulation Hold: Prevents pull-through or edge tearing of soft or rigid insulation boards.

Applications

• Thermal Insulation Fixing: Secures mineral wool, rigid foam, or fibrous insulation boards to concrete, masonry, or metal substrates.
• Acoustic Insulation Installation: Provides firm hold for soundproofing panels in partition or ceiling systems.
• Refurbishment Works: Suitable for re-insulating existing walls requiring even fixing pressure.
• Drylining Systems: Used with mechanical fixings to hold insulation behind plasterboard linings.

Installation Guidance

• Surface Preparation: Ensure substrate is clean, stable, and capable of receiving mechanical fixings.
• Fixing Selection: Choose appropriate anchor or screw fixing based on substrate type and insulation thickness.
• Disc Placement: Position the disc flush against the insulation surface before inserting the fixing through the central aperture.
• Tightening: Secure fixings until the disc sits firmly without compressing or damaging the insulation.

Compliance & Performance

• Material Specification: Manufactured from zinc-plated mild steel for strength and corrosion resistance.
• Corrosion Protection: Zinc coating meets standard protection levels for interior and sheltered exterior use.
• Thermal Performance: Disc profile designed to maintain insulation integrity without thermal bridging.
