The National Structural Timber Specification for Building Construction (NSTS)
In This Series
The National Structural Timber Specification for Building Construction (NSTS) is an ambitious initiative by TRADA to support the rapidly increasing use of timber. It aims to be the definitive, comprehensive, stand-alone national specification for structural timber, complementing the existing national specifications that are widely used for steel and concrete buildings.

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...
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...
