Greenstone Building Products
Greenstone Building Products manufactures the GS Panels for residential, commercial, and industrial buildings. GS Panels are a prefab structural insulated panel featuring an engineered combination of expanded polystyrene and galvanized steel. This combination results in a much lighter, stronger, and energy efficient building envelope. Locally owned and operated in the heart of the Canadian prairies, Greenstone operates out of Brandon, Manitoba.
With CFS, Greenstone now delivers a complete building solution – combining the energy efficiency of a GS Panel envelope with the strength and precision of cold formed steel.
