History of MSL Fibre
The original Louiseville mill was built in 1946. Between 1946 and 2004, it was successively purchased by Air-Cell Insulation, Barrett Co., Allied Chemicals Canada and Canadian Gypsum and eventually bought by Cascades (Les Matériaux Cascades inc.) in 1980. Matériaux Spécialisés Louiseville inc. (MSL) acquired the mill in 2004.
MSL has built a solid reputation over the years and is a leader in the development of environmentally friendly products. The MSL mill operates with a completely closed (zero effluent) water system resulting in an efficient and environmentally friendly process. MSL’s fibreboard panels are made with natural, non-toxic materials. They are dimensionally stable, lightweight and easy to install. Recycling and the protection of the environment will always be part of MSL’s core values.
