The Lambert tile factory has existed for 142 years in Saint-Adjutory in Charente. Six generations have succeeded each other to produce today 13,000 pure clay roof tiles per day. The company did not wait for the energy crisis to launch a plan to reduce its electricity and gas consumption. Investments have been made in this direction since 2015.
