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

Rockwool SP Firestop Fixing Brackets Large supplied in packs of 50. 

Galvanised steel fixing brackets designed for secure installation of Rockwool SP FireStop Slabs within curtain walling, floor, and compartment interfaces. The brackets maintain correct slab positioning, compression, and edge contact to achieve rated fire performance within approved systems.

Each bracket is pre-formed with locating tabs and fixing holes, allowing quick attachment to concrete, steel, or masonry substrates. The galvanised finish provides long-term corrosion protection in typical internal or sheltered building environments.


The large bracket size is intended for wider cavity widths and deeper installations, providing consistent restraint and compression along fire-sealing junctions.

Features & Benefits

  • Purpose-designed restraint: Ensures Rockwool FireStop Slabs remain securely in place under fire exposure and thermal expansion.
  • Durable material: Manufactured from galvanised mild steel for strength and corrosion resistance.
  • Ease of installation: Pre-formed fixing holes simplify alignment and fixing to concrete, steel, or masonry.
  • Consistent performance: Maintains slab compression and edge contact for optimum fire seal integrity.
  • Pack quantity: Supplied in packs of 50 for efficient site application and stock management.
  • Bracket size: Large bracket for wider cavity widths and deeper installations.


Applications

  • Curtain walling interfaces: Used to fix FireStop Slabs between floor slabs and external façades.
  • Compartment walls and floors: Secures fire-stopping slabs in masonry and steel-framed structures.
  • Service penetrations: Provides mechanical restraint for FireStop material around voids and openings.
  • Façade perimeters: Maintains consistent slab positioning at vertical and horizontal barriers.


Installation Guidance

  • Mark fixing points: Determine bracket spacing and position according to Rockwool FireStop installation guidance.
  • Fix bracket: Attach to substrate using suitable mechanical fixings (typically one per bracket).
  • Insert slab: Fit slab under light compression between brackets to ensure continuous contact.
  • Check alignment: Ensure brackets do not distort slab face or compromise compression.
  • Inspect after installation: Confirm secure attachment prior to applying any finishing layers.


Compliance & Performance

  • Material specification: Galvanised mild steel in accordance with BS EN 10346.
  • Corrosion protection: Hot-dip galvanised coating suitable for internal and sheltered environments.
  • Fire system compatibility: Designed and tested for use with Rockwool SP FireStop Slabs.
  • Pack details: 50 brackets per pack.
  • Important note: Use only in accordance with Rockwool FireStop system installation instructions to ensure rated fire performance.
