HARMONY TECHNICAL SPECIFICATIONS FOREWORD Harmony Roof Tiles has great pleasure

HARMONY TECHNICAL SPECIFICATIONS FOREWORD Harmony Roof Tiles has great pleasure in presenting this Technical Manual to the industry and take this opportunity to explain a little more about its background. For a number of years, our company has been aware of the need to provide our clients with more detailed information about fixing concrete roof tiles, that is to include information for bricklayers, roof carpenters and roof plumbers. We also realised the need to improve the assistance given to architects, engineers and designers by providing more detailed information for their design work. Although this manual has been published primarily for these reasons, other information has been included such as product details of both tiles and accessories, standards and fixing procedures. We believe that this Technical Manual will go a long way in answering all of your questions concerning performance and fixing of Harmony Roof Tiles.
