Jacques Roulland, who has now retired from selling felts and a few other tools for the fibre-cement industry, visited large and small factories in around forty countries on four continents for around 30 years. After writing a first book about the company he worked for, he wanted to write the completely unknown history of the fibre-cement industry. For this purpose, he managed to meet and interview many engineers and workers whom he had come to know over the years. The result was a French book, in 2019, a Spanish adaptation in in 2020, with the help of several experts from Spain and Latin America. And now comes the English version, proofread by a very kind and experienced lady working for a long time in the fibre-cement world.
