This handbook summarizes concisely, in diagrams and brief explanations, all elements of construction. Practice, techniques, components and procedures are clearly defined with supplementary references to regulations and relevant standards. This fourth edition has been extensively updated. In particular the section on thermal insulation has been substantially expanded and updated to take into account changes in Part L of the Building Regulations "Conservation of Fuel and Power." All sections have been updated to include reference to revised British and European Standards, regulations and legislation. Further references and explanations have been added to aid the reader's understanding. This should be a useful text for all students of construction and related subjects and is a valuable reference text for construction professionals.
