Zinc-Plated Insulation Discs 85mm (50/Box)

Zinc-Plated Insulation Discs with an 85mm diameter. Designed for securing insulation materials to substrates where a broad, stable bearing surface is required. The discs feature a shallow, rigid form that distributes load evenly, preventing insulation compression and maintaining thermal integrity across fixing points. The zinc-plated steel provides enhanced corrosion resistance, ensuring long-term performance in both internal and sheltered external applications. Compatible with mechanical or screw fixings, these discs offer secure retention and a consistent surface contact for insulation boards or quilt materials.
