Fire Treatment

Fire Retardant Treatments
||
As timber has a high structural strength and slow charring rate, its general behaviour in a fire is predictable. Fire retardant treatments slow the rate at which fire develops, giving more time for a safe escape.

Understanding Fire Protection Terms – Classification without further testing (CWFT)
||
In some cases, it is possible to classify untreated wood-based products without further testing as long as these products meet the requirements set out in the relevant harmonised technical specification.

Flame Retardant Treatments
Flame Retardant Treatments for Timber – An Overview
||
Flame Retardant (FR) chemical treatments for timber work by reducing its ignitability, slowing down the surface spread of flame and, as a result, reducing the heat released. This allows more time for escape in a fire situation.

Reaction to fire and Fire resistance
||
Reaction to fire classifications are completely different to fire resistance ratings yet the two terms are often misunderstood and taken to mean the same thing. This is not the case. This publication aims to set out the important differences. Understanding fire performance terminology starts with understanding the stages in the...

Assuring Quality – The Flame Retardant Treated Wood Supply Chain
||
Where a flame retardant (FR) is added in the factory during the manufacturing process for MDF, OSB or plywood then that manufacturing process should be subject to factory production control (accredited by a notified body). The product should carry the CE mark and be accompanied by a valid Declaration of...

Understanding Fire Protection Terms – Combustibility
||
There are four recognised stages in the development of any fire: Ignition, Spread and Growth, Flash point into a fully developed fire and Eventual Decay. During the early stages, when a fire is still becoming established, the important factors are: Ignitability, Spread of Flame, Smoke Production and Flaming droplets.

Understanding Fire Protection Terms – Service Environment
||
It is vital that any flame retardant treatment incorporated into a building provides long-term, predictable performance backed by independent verification. Before specifying enhancement using a flame retardant, two specification fundamentals must be established: What reaction to fire performance is required? and What is the service environment?.

Fire Rated Wood-based Products & CPR
||
CE marking of construction products (those and only those covered by a harmonised European standard) is mandatory under the Construction Products Regulation (CPR). Harmonised standards include guidance on the minimum information that should be included with the CE mark.

External Timber Cladding and Fire Risk
||
Building Regulations are intended to ensure that a reasonable standard of life safety is provided in the event of fire. The appropriate use of timber products can play a critical part in improving the performance of buildings in fire situations and in extending the time available to occupants to exit...

Understanding a Fire Test Classification
||
Wood and wood-based panels can perform well in fire if they have been enhanced using a factory controlled process to either impregnate them with flame retardant (FR) or apply an FR coating to the surface. Panel products can also be manufactured containing a flame retardant. In all cases, the products...
