Preventing Failures in Roofing and Wall Systems: Evaluating Antimicrobial Performance in Building Materials

Antimicrobial additives are used in roofing systems, wall assemblies, coatings, and sealants to control mold and algae growth. For architects and contractors, the goal is to protect materials from damage and help them last longer in real-world conditions. Performance, however, depends on more than just adding an antimicrobial. Jobsite conditions such as moisture, temperature swings, and environmental exposure are common threats and can directly affect how well these additives perform. This session examines how antimicrobial systems are formulated, tested, and evaluated using standards such as ASTM G21, ASTM D3273, and MIL-STD fungal resistance testing measures. It also explores how and where real-world performance and where gaps can occur. Attendees will gain a clearer understanding of how to asses antimicrobial effectiveness make more informed material and specification decisions. Attendees should have moderate to advanced knowledge of/experience with: Coating selection, roofing systems, wall assemblies, or material specification decisions.

Upon completion of this course, the Learner should be able to:

• Define what an antimicrobial additive is and what makes them successful
• Understand how antimicrobial performance is evaluated using industry-standard test methods
• Discover how testing and interpretation can affect materials, product specifications, and ultimately the longevity of products and projects
• Learn how antimicrobial additives work in various environmental conditions

Approximately 1 hour. Delivered via webinar or face-to-face presentation. Available sessions shown below.
