Rainscreen wall assemblies are contemporary cladding systems predominantly defined by their functionality. Common characteristics of rainscreen assemblies include the selected cladding material and track subframe as well as continuous air and moisture control layers, insulation, flashing, and air space. Claddings/veneers integral to rainscreen wall systems that are often installed by BAC craftworkers include terra cotta, stone, tile, and GFRC panels.

Rainscreens have become increasingly popular over the past several years as building science concepts have been further developed and more materials and systems have entered the market. BAC craftworkers, as well as IMI, will continue to be on the front lines of rainscreen design and construction to ensure attractive and quality installations.

Installer Certifications & Training

Rainscreen Certificate Program

Many rainscreen details differ from one project or manufacturer to the next, so installers must be experienced and careful. This certificate gives BAC craftworkers practical experience installing a range of rainscreen cladding and subframing systems. 

Flashing Upgrade Training

Proper flashing is one of your building’s best defenses against moisture. BAC craftworkers stay up-to-date on the latest techniques and building code requirements with IMI’s Flashing Upgrade Training Program. 

Air Barrier Certificate Program

Air barriers help prevent air and moisture from entering the building envelope. This course teaches craftworkers how air barrier assemblies function, including how to evaluate materials, substrate conditions, and the continuity of components. 



IMI is a founding member of the Rainscreen Association in North America (RAiNA), the leading authority on rainscreen assemblies. IMI technical staff are active in several RAiNA committees, including the Education and Training Committee. As a participating member, IMI assists in ensuring that best practices are developed and implemented, not only in the detailing of rainscreen assemblies, but also in the installation of the materials that comprise the assemblies.
