Fire Safety

The thickness of plank decking makes it a more fire-resistant material compared to panel and board sheathing. For this reason it is often used in large commercial buildings where fire performance must meet Heavy Timber construction requirements for fire safety and where the superior appearance characteristics of this material are desired.

The Wood Reference Handbook provides further information on building code requirements relating to fire safety and details the minimum size requirements for Heavy Timber construction including minimum thicknesses for decks.
