Wind Webinar & Technical Article

Wind Design for Modular Vegetated Roof Assemblies

Webinar about the CSA A123.24: Standard Test Method for the Wind Resistance of Modular Vegetated Roof Assembly (VRA) reviews the two key test components that measure wind uplift and wind flow resistances. Videos & case studies help demonstrate how VRAs behave at different wind pressures and wind speeds.

Protecting Vegetated Roofs from the Wind – Technical Article

Read Dr. Karen Liu’s Construction Canada magazine article to determine a vegetated roof’s ability to withstand and protect against wind forces.
