The HempLime Handbook: Welcome to the world of natural building

The HempLime handbook by HES is a perfect companion for Architects, Builders, developers and entrepreneurs who are in, or wish to enter the world of building with HempLime. The HempLime handbook serves as a guide to understanding the fundamentals of HempLime by providing detailed description of the raw materials, uses, benefits, limitations, mixing recipes, application methods, specification and pricing, construction tips and techniques, life cycle analysis, product testing and real world examples of what not to do. HempLime is a truly ecological material which has been tried and tested as thermally insulating and fire retardant , according to strict EU standards, as well as being used successfully in over 50 000m2 of building and renovation. HempLime provides a healthy indoor climate for all occupants and has been used in applications to regulate moisture issues such as in cellars. The HempLime handbook has been produced by the Hemp Eco Systems Group, with a mission to promote the use of natural building materials, and is a compilation of 30 years of experience building and renovating with HempLime. The HempLime Handbook forms the basis of the HES certified training programme and is an essential piece of literature for anybody wishing to specify and install HES products. For the first time, we have included the full life cycle analysis of HempLime which shows that it is in fact a CO2 negative building material.
