How can a rainscreen be a high-performance envelope option? This presentation will focus on the primary features of a rainscreen wall as defined by RAINA. The presentation will then move towards a focus on thermal performance of walls and how the integration with RS can occur. Attention will be given towards addressing varied façade panel manufactures warranty requirements and how this can narrow options within the rainscreen composition. Challenges with substructure design i.e. dynamics, deflection, expansion joints and cantilevers, secondary membrane positioning, perforated girts. How facades contribute to sustainability within the built environment as the PPECs (Primary Passive Environmental Control System) Finally – the rainscreen as a high-performance envelope design

Learning Objectives:

• Comprehend the fundamental principles and components of a Rainscreen design, including its purpose, key features, and advantages.
• Articulate how thermal performance concerns can be effectively managed and improved through the implementation of Rainscreen.
• Demonstrate an understanding of the flexibility of Rainscreen systems to accommodate the specific requirements of facade panel manufacturers/materials while complying with RAiNA’s definition of Rainscreens.
• Recognize the significance of Rainscreen systems as a critical component contributing to sustainability.

Laverne Dalgleish

Executive Director, Rainscreen Association in North America

Mr. Laverne Dalgleish is the Executive Director of the Air Barrier Association of America (ABAA) and the Rainscreen Association in North America (RAiNA). As such, he works to champion energy conservation in buildings while educating the building owners and designers about the benefits of energy conservation such as durability, comfort, reduced maintenance, reduced HVAC equipment costs and the positive impact on the environment. Mr. Dalgleish travels North America on a weekly basis to educate building owners and designers on the benefits of effective and working air barrier systems in buildings. This education mission includes working with standards development organizations, training and education groups, government policy departments, and quality assurance program developers for the construction industry. Mr. Dalgleish is the Secretariat of two ISO Committees, ISO TC61 SC10 Cellular Plastics and ISO TC163 SC3 Thermal Insulation Products. He is also Chair of the ULC Thermal Performance in the Building Environment Standards Committee.  Mr. Dalgleish was the key developer of the ABAA Quality Assurance Program for the installation of air barrier systems in buildings. This program is based on ISO9000 and ISO 12576-2 but brings the ISO requirements together with practical applications for the air barrier industry.
