Additional guidance from TRADA Technology Timber frame construction is the core of a suite of publications from TRADA Technology about building in timber frame. Visit www.trada.co.uk/bookshop • Low energy timber frame buildings: designing for high performance – this book deals with building orientation, passive and active solar technologies, and design of the building envelope • Standard details for thermal performance – a suite of details based on our standard detail publication and the new detailing in this 5th edition of Timber frame construction. The details include thermal conductivities of materials, U-values and ψ-values • TRADA Wood Information Sheets – our popular WIS series covers single subjects, including many relating to timber frame • Span tables – published in two versions (BS 5268-2 and Eurocode 5) these contain section sizes and spans for solid timber members in floors, ceilings and roofs (excluding trussed rafter roofs) for dwellings • EC5 Timbersizer – using timber sizes readily available in the UK market, this online application suggests appropriate cross-sections based on the timber strength classes or joist depth • EC5 Timberconnections – for a giving timber strength class this online application calculates the load capacity of individual fasteners (nails, screws, bolts, dowels and coach screws) in two- and three-member combinations of timber and steel.
