VERTICAL FIRE SEPARATION

Fire Separations

In order to meet the performance requirements of Building Codes, the most important solutions specify a number of safeguards (fire separations) to control fire and smoke spread. They are required to stop fire and smoke passing in both directions. 

Two way fire separations will be required between:

1. public seating areas and storage zones in a stadium;

2. commercial / office spaces and a fire stair or fire corridor;

3. fire / ventilation ducts and floor to floor compartments;

General benefits of the LAF system

The most beneficial attribute offered by our LAF separating construction system is the low weight and reduced thickness in achieving the maximum required FRL period of four (4) hours. The system can be suspended from superimposed structures, or supported from other fire rated elements with minimal structural prerequisites.

TWO WAY FIRE RATED PROTECTION

With most types of bulkheads and ceiling systems it is imperative that the fire source be ascertained before a pertinent system can be designed. In the case of ceilings over fire isolated passageways and stairs, the Ceiling will ideally need to prevent fire from spreading into the passageway / stair rather than contain the fire inside the compartment. The LAF separating construction system offers a ‘two way’ fire rating as is required over fire isolated paths and/or stairs.

LAF separating construction systems can also provide air-tight enclosures for high pressure return air shafts. They are self-supporting and provide protection from fire in either direction. This is a most convenient system when confronted with difficult access situations, such as upgrading walls with restricted access from both sides.

Sacrificial Suspension System

Services required to be attached/suspended from the LAF separating construction system, should be independently supported without reliance on the system itself. Support details should be carefully planned to ensure compliance with regulatory requirements. 

LAF separating construction system is ideal for very high partitions where additional structural members can be installed at the necessary centres to break-up the overall height. In many instances the system has been approved for use in providing separation for fire lift shafts where the available space to install such fire barriers is often scarce.

VENTILATION SHAFTS IN TUNNELS: THT MODULAR CEILING SYSTEM

Walls Design for dead and live load

In all tests for the Trimesh® Vermitex® two way wall system we present a case where the wall is a non-load bearing element and therefore load considerations are not required, however the LAF two way system can be re-engineered by changing the internal steel rods or providing additional external supports to cater for loads up to 5,000 Pa.
