How do fire regulations affect timber facade design?

Fire regulations for timber facades vary by building height and jurisdiction. In England, buildings above 18 m require non-combustible cladding (effectively prohibiting timber) following the Building Safety Act 2022.

Fire regulations for timber facades vary by building height and jurisdiction. In England, buildings above 18 m require non-combustible cladding (effectively prohibiting timber) following the Building Safety Act 2022. Below 18 m, timber cladding is permitted subject to cavity barrier provisions and Euroclass B rating (achievable with fire-retardant treatment). In Scotland, Wales, and most European countries, timber facades are permitted on taller buildings with appropriate fire engineering (cavity barriers every 10 m vertically, sprinkler protection, fire-resistant backing). Always verify current local regulations.
