Webinar – Interior Wall and Floor Assemblies in Mid-Rise Multi-Family: Designing for Fire, Acoustics & Structure

December 8, 2021 – 12:00 pm - 1:00 pm




Join at 10 am Pacific, 11 am Mountain, 12 pm Central, 1 pm Eastern

What are the pros and cons of using a single stud wall vs. a staggered stud wall for dwelling unit separation? Do you need sprinklers or fireblocking in the floor cavity of your wood joist floor assembly? How can you meet code requirements for fire-resistance continuity of corridor walls while also having numerous mechanical elements puncturing those walls? If you have questions like this, you won’t want to miss this webinar focused on practical solutions for commonly asked multi-family design questions. Join us for this third session in our 2021 series of deep dives into this topic as we take a step-by-step approach to the design and selection of interior walls (unit demising, corridor, shafts and firewalls) and floor/ceiling assemblies and discuss how the fire-resistance, acoustical performance and structural load resolution of these assemblies can be simultaneously achieved. We’ll analyze example details and assemblies, contrast different assembly options, learn how to make modifications to tested wall assemblies, answer questions that arose during the first two sessions in this series, and look at tools you can use to evaluate your options.
