More About This Title Goss's Roofing Ready Reckoner - From Timberwork toTiles 5e
English
Goss’s Roofing Ready Reckoner provides cutting angle and lengths for traditional ‘cut’ roofs and design tables for timber sizing, based on BS5268 ‘Structural use of timber’ and now including a comparison of timber sizes using Eurocode 5 ‘Design of Timber Structures’. Additional information is provided on wall plate and gable strapping, wind bracing, truss clips and other roofing metalwork, plus information on tools, equipment and health and safety matters. Detailed drawings for tiling, slating and other roof coverings are included, with fixing requirements revised to BS 5534:2014. Information on lead substitutes and roofing putties is also provided. Design of warm and cold roofs is fully covered, including ventilation and insulation requirements. The fifth edition also includes new chapters on engineered timber roofing components, solar panel fixing and outbuilding roofs.
