Full of detailed construction drawings, this book covers cut roofs, bolted truss roofs, trussed rafter roofs, trimmed openings and ventilation.A major section deals with loft to attic room conversions, giving guidance on planning procedures, as well as dealing with structural matters and specifying conversion work.The Fourth Edition features a new chapter covering the growing number of engineered timber components available in the house building industry. The use of I beams and roof cassettes is detailed for roof and room-in-the-roof construction. The text has been fully updated to current standards and features additional detailed construction drawings. The chapters on attic conversion and construction have been expanded and a new attic conversion decision flow chart added.The book will prove invaluable to architects, house builders, roof carpenters, building control officers, trussed rafter manufacturers and students of building technology.The AuthorC.N. Mindham BSc has had a wide experience in the construction industry. After three years with TRADA as Eastern Regional Officer, he spent 11 years developing a timber engineering business to become one of the country's largest producers of trussed rafters.He became Managing Director of a company designing and manufacturing trussed rafters, joinery and prefabricated timber buildings, a post he held for eight years. Subsequently he started his own consultancy for the timber industry which has led him to his current position as Managing Director for a joinery and engineering company.Also of interestLoft ConversionsJohn Coutts1-4051-3043-19781-4051-3043-1The Building RegulationsExplained and IllustratedTwelfth EditionM.J.
