UK-grown timber is often perceived to have “low quality”, and most of the UK’s sawn timber is used for fencing and packaging material. Much of the resource could be used as construction timber, as UK spruce and other softwoods can be strength graded... Read More about Can you guess the strength of timber? How (your) wood quality perceptions relate to reality.

A little about the verification of a lot (EN 14358) (2022)
