Craft training is performed through the International Masonry Training and Education Foundation (IMTEF)
Masonry rain screen walls have to control the movement of moisture, air, vapor and heat… and look good doing it. They take many forms, from simple, ventilated or pressure-equalized walls to open-jointed cladding systems. In general, they are cladding systems (typically terra cotta, calcium silicate, natural stone or porcelain tile) attached to the substrate with a metal rail support system over an air/water/vapor barrier to let air flow into the wall but not into the building.
The International Masonry Institute (IMI) is a strategic alliance between the International Union of Bricklayers and Allied Craftworkers and the contractors who employ those members. Through education, technical support, research and training the IMI works to provide a more efficient construction delivery system.
