When working with mineral wool, rockwool, or glass insulation, the right fixing makes all the difference. If the washer is too small, you risk pull-through; if the material is low-grade, you risk long-term corrosion.
We are proud to offer the only 70mm A4 stainless steel washer in the UK specifically engineered for these high-performance insulation types.
Why the ID4-70 is a game-changer for your next build:
- Maximum Surface Area: The 70mm diameter provides the essential load distribution needed to secure soft mineral wool and glass insulation boards without damaging the material.
- Marine-Grade Durability: Crafted from A4 Stainless Steel, these washers offer the superior resistance to corrosion, essential for coastal projects or harsh industrial environments.
- Specialist Compatibility: While others use generic fixings, the ID4-70 is purpose-built for mineral wool and rockwool applications where stability is non-negotiable.
