How delivery works
We work with a nationwide network of trusted suppliers. Items in your basket may be supplied by different suppliers and delivered separately. Where this applies, you will see delivery charges shown at checkout for each part of your order. We always aim to group products from the same supplier to keep delivery costs as low as possible.
Delivery areas
Delivery charges apply to mainland UK, excluding: AB, CA, CF, DD, DG, EH, EX, FK, KA, KW, KY, IV, LA, LD, LL, ML, NP, PA, PH, PL, SA, SY, TR, TQ and TD.
If your address is in one of these areas, we will contact you before processing your order to confirm any additional costs. We do not currently offer delivery outside the UK mainland.
What to expect on delivery day
- Deliveries are typically kerbside.
- Please ensure someone is on-site to accept delivery. For heavier items, help with offloading may be required.
- Many building materials arrive on large vehicles. If access is restricted, a specialist vehicle such as a HIAB may be required and could incur an additional charge.
Why delivery can cost more than typical parcel delivery
Building materials often travel on larger vehicles and usually carry fewer drops per run than parcel networks. That is why delivery charges can be higher than standard e-commerce shipping.
Returns
Returns depend on what you have bought and whether there is anything wrong with it. For full details on eligibility, timeframes, and exclusions, please see our full policy.

Product Overview
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.
Features & Benefits
- Broad contact surface: Provides even pressure distribution, reducing risk of insulation damage during fixing.
- Zinc-plated finish: Protects against corrosion, maintaining integrity in 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: Used to secure 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 where even fixing pressure is required.
- Drylining systems: Used in conjunction 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 applied to meet standard protection levels for interior and sheltered exterior use.
- Thermal performance: Disc profile designed to maintain insulation integrity without creating significant thermal bridges.
- Dimensional accuracy: Produced to consistent tolerances ensuring correct fit with standard insulation fixings.
- Important note: Ensure compatibility between disc, fixing type, and substrate to maintain secure and durable installation.
