Developed to provide up to 4 hours fire stopping at the junctions of compartment walls and floors.
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)
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
