Passive Fire Protection (PFP) – a perfect solution with Microtherm®.

Passive fire protection (PFP) – with Microtherm®

Fire prevention involves a series of stages - anticipation, selection of fire resistant building materials, provision for early detection of a fire, active fire protection such as sprinkler systems, and finally, passive fire protection

If a fire takes hold and active protection systems fail to suppress it or quench it completely, the final element of protection is containment of the fire such that evacuation of a building (or boat, train, or aircraft) can safely take place. This is where the performance of Microtherm® insulation is invaluable.

The aim of passive fire protection (PFP) is to contain fires or to slow the spread, through the use of fire resistant walls, floors, and doors. This fire resistance is conventionally achieved through either the protection of a surface insulation covering, or by an intumescent or ablative coating.

Passive fire protection systems require the very best thermal insulation performance for maximum protection duration. The same principles apply whether the protection is for a building or for some form of passenger transport. Passive Fire Protection, whether by insulation protection or a surface coating, is intended to contain a fire in the area where it starts and limit the spread of fire and smoke to adjoining compartments or rooms for a defined period of time. As a system, it is likely to include a number of components such as fire resistant walls, ventilation dampers, fire stop doors etc., all individually fire rated and all interacting to achieve the desired level of protection.

A thermal insulation for passive fire protection must be non-combustible and able to withstand the high temperatures of a fire for the duration of the protection period and to maintain its integrity. It should also be compact and lightweight, particularly when used to protect passengers in ships, trains, aircraft, or vehicles.

Because of the combination of low density, superb thermal performance, and non-combustibility, Microtherm® systems easily meets all of these criterias and are therefore widely used in PFP applications. Microtherm® performance and the reasons why it is the best insulation available are explained in Microtherm® – a perfect insulation elsewhere on this web site.

In marine PFP, a Microtherm® "air gap" system is the lightest on the market. A Microtherm® "contact" system is the most compact on the market. Microtherm® systems offer the best PFP solutions for all materials including composites.

In railway PFP, a lightweight Microtherm® system provides the thinnest protection to the underside of aluminium carriage floors to meet standards such as EU45545 and ASTM E119. Systems are also available for full contact protection for laminated and foam filled composite structures.

In building PFP, a Microtherm® system offers the thinnest protection for elevator shaft access fire doors to European Standards DIN EN 1363-1 and DIN EN 1364-1, and EN 81-58:2003. Microtherm® hydrophobic flexible panels have provided total protection to structural steelwork and can be fitted in exposed locations in all weathers.

More information about all this can be found on the pages Passive fire protection, Microtherm® in rail applications, and High performance elevator shaft fire doors on this web site.

Microtherm® is the best high temperature insulation you can buy. This can be clearly seen on the Comparison TCs chart featured on our home page.
