Pallet of Rockwool FirePro SP Firestop EN

Rockwool FirePro SP Firestop EN is a specialist stone-wool firestopping product used in tested construction details to limit the spread of fire and smoke through designated cavity or linear-joint locations. It should be selected from the building's fire strategy and the manufacturer's system documentation, rather than treated as interchangeable with ordinary thermal insulation.

Rockwool FirePro SP Firestop EN for specified cavity barriers

The live product lists two pallet options: 75 x 1000 x 1200mm, 32 sheets, or 90 x 1000 x 1200mm, 24 sheets. The existing description refers to specific fire-test standards and resistance periods. Fire resistance is only established for approved constructions and installation arrangements, so check the exact test and classification reports for the intended wall or façade system.

Product options and dimensions

• Pallet of Rockwool FirePro SP Firestop EN
• Dimensions: 75x1000x1200mm (32 Sheets), 90x1000x1200mm (24 Sheets)

How to choose the right specification

Confirm cavity width, substrate, joint type, required fire resistance, movement allowance, orientation and specified supporting fixings. Details involving masonry, steel framing or façade systems can require different configurations. A fire-rated product on its own does not prove that a complete assembly achieves the desired classification.

Installation, planning and maintenance

Installation should be carried out by competent operatives using the complete approved firestopping detail, including required compression, brackets and seals. Keep records of the product and installation where required by the project. Never cut, compress or substitute firestop components outside the tested system arrangement.

Roof Tiles & Fittings:
