Features & Benefits

• Up to 4 hours fire resistance
• Suitable for walls ranging from 400kg/m³
• Manufactured for a wide range of profiles
• Easy installation
• All fire ratings apply to gaps over walls constructed of dense aggregate blocks, lightweight aggregate concrete, clay bricks or concrete blocks with a minimum density of 400Kg/m³
• Fire resistance includes integrity and insulation criteria to BS 476: Part 20: 1987

Application

Linear and Trapezoidal Firestop Systems have been developed to provide up to 4 hours firestopping at the junctions of compartment walls and floors.

Solutions illustrated are for masonry walls with a density of at least 400 kg/m3 and include both fire integrity and insulation criteria for concrete decks, composite decks and simple profiled sheeting.

Linear Firestop 2A

• Rectangular strips (installed under min. 5% compression)
• Thicknesses: 12.5, 20, 30, 40, 50, 60, 70, 80, 90, 100mm
• Widths: 100, 150, 200, 300, 400mm
• Fire resistance: Up to 4 hours

Trapezoidal Firestop 2B

• Trapezoidal strips (tight fit required)

Available for all profiled decks. Deck profile to be named at time of order, e.g. Ribdeck 60, Alphalok etc.

Dovetail Infill Firestop Strip

• Supplied as narrow rectangular strips for pinched installation into nominated dovetail shaped deck profiles; e.g. Holorib, Quickspan, Q51

Installation

Please see Product Data Sheet and Installation Guide for detailed installation instructions.

The following installation requirements must be met in order to reliably achieve the stated fire resistances.

• Linear Firestop 2A must be fitted as rectangular pieces, tightly butt jointed and compressed by at least 5% in thickness
• Up to 3 layers may be used. Single layer firestopping will always be preferred, with multi-layer methods limited to those occasions where building tolerances demand practicality. All layers should be installed simultaneously. The height of void should not exceed the width of the Firestop
• Gaps associated with perimeter floor slab/wall fire stopping should be achieved using Rockwool SP Firestop Systems
• Linear and Trapezoidal Firestop materials are light and easy to handle and should be cut using a sharp bladed knife. Store in dry conditions
• Once installed, Linear and Trapezoidal Firestop materials will need no maintenance unless disturbed
• For areas such as clean rooms, Firestop systems are available totally enclosed in shrink wrap
