Wood-based panel products and timber in fire
This Wood Information Sheet (WIS), intended for designers, specifiers and manufacturers, covers the behaviour of wood-based panel products such as plywood, particleboard and fibreboards, in addition to timber.
Smoke production is also considered.
This Wood Information Sheet applies to the United Kingdom and other jurisdictions where British practice is followed.
It is important to have tests acceptable in the jurisdiction where products are intended to be sold. This WIS explains the system of testing for wood-based panel products and timber, and is predominantly based on European test Standards. The European system is accepted in all European countries and will continue to be the recommended testing system in the UK even after Brexit.
- Reaction to fire
- Fire resistance
- Smoke production
- Fire performance during construction
This WIS sheet was revised in August 2020 to include changes to: Building Regulations, reaction to fire definition, fire resistance.
This Wood Information Sheet gives guidance on assessing the suitability of existing doors for upgrading to give a 20 or 30 minutes' fire resistance comparable with that of purpose-made fire doors. Upgrading to 60 minutes' performance will rarely be possible.
Upgrading the fire resistance of existing doors is a...
This Wood Information Sheet, produced in association with the UK Timber Frame Association, explains the basic principles used in meeting fire performance requirements and provides guidance to ensure that all parties involved understand their role in the design and construction of a timber frame building.

In many situations, timber and wood-based materials may be used in their natural, untreated state. However, flame-retardant (FR) treatments extend their use to situations that demand enhanced 'reaction to fire' properties.
This Wood Information Sheet (WIS) covers treatments that may be applied to wood and wood-based products both...
