Magnesium Oxide Panels: A Durable, Fire-Resistant Alternative for Modern Construction
Exploring the Strength, Safety, and Versatility of MgO Boards
Sponsored by TAMLYN
Live Webinar Airing on June 5, 2025 at 02:00 PM ET
Magnesium Oxide (MgO) panels are revolutionizing the construction industry by offering superior fire resistance, exceptional durability, and resistance to moisture, mold, and pests. As an alternative to traditional materials like OSB, plywood, gypsum, and plaster, MgO panels provide high flexural strength, increased fastener withdrawal resistance, and enhanced impact performance.
In this webinar, we will explore the structural benefits of MgO panels, their role in fire-rated assemblies, and how they contribute to safer, longer-lasting buildings. Industry professionals will gain insights into the latest advancements in MgO technology and its applications in residential and commercial projects.
Join us to learn how Magnesium Oxide panels are reshaping modern construction with their unmatched strength, safety, and sustainability. After the presentations, there were will be a Q&A session to discuss key points from the webinar.

TAMLYN is a family-owned company with 50 years in the building products industry and has placed a great deal of recent focus on building science, especially moisture management. This direction led to the development of their TamlynWrap® line, Drainable with its 1.5mm bonded filament creating an enhanced WRB, and RainScreen 6.3 (1/4”) and 10.1 (3/8”). TamlynWrap® RainScreen is a multi-layer water management system, intended for use over existing WRB or coated sheathing, of cavity spaces that are non-compressible and act as a furring matrix to promote enhanced drainage and drying, paired with improved installation efficiency.
