Wood Durability Guide: Timber Durability Chart & Database
We want our gates and garage doors to last as long as possible, so we use timber like Accoya because of its durability, hardness and suitability for our products.
We’ve put together some resources about Timber Durability to help you choose the best timber for your gate or garage door, or whatever you’re looking to make.
The Timber Durability chart contains 5 classes of timber, with each class determining how long each timber listed will last – these are all to BS EN 350-2:1994 – Durability of wood and wood-based products. Natural durability of solid wood. Guide to natural durability and treatability of selected wood species of importance in Europe.
The Timber Durability Database is a table of durability grades/ratings by wood type, with images to match.
We created some useful graphics that show these details – they’re good for quickly referencing each timber, or you can print them off and keep them in your workshop!
