Guides
Detailing decides how long timber lasts.
Material choice sets the ceiling. Detailing decides whether you reach it. These guides translate building physics into drawable rules.
Construction detailing
Timber frame construction details
Sill, wall, opening, eaves and junction detailing rules that keep a timber frame dry, ventilated and durable for decades.
Read the guide →Biological degradation
Wood decay and wood rot
The four conditions decay fungi need, how brown, white and soft rot differ, how fast decay advances, and where design actually intervenes.
Read the guide →Specification
Durability classes and use classes
EN 350 durability classes and EN 335 use classes, how to match material to exposure, and why a class is not a service life.

Wood moisture content
Targets by environment, the 20 % decay threshold, how to measure reliably on site, and how much timber moves as it dries.

Wood treatments compared
Oils, coatings, silicate and silane treatments, preservatives, modified wood and fire retardants — set against UV, decay, termites and fire, with the standards that measure each.
