I.S. 440: 2009+A1:2014 “Timber Frame Construction, Dwellings and other Buildings” is the Irish standard on timber frame construction.
The standard refers to responsibilities, materials, design (to Eurocode 5), manufacture, construction details, site work and services.
Work on the revision of I.S. 440 commenced in 2015, largely to bring it in line with the requirements of different European standards, the Construction Products Regulations and recent changes to the Building Regulations framework.
