PowerHour by PowerWool™
For decades, most walls have been insulated the same way: fill the stud cavities and call it a day. But as building science evolves, many builders and architects are rethinking that approach. Have we been doing it wrong?
Join us for a webinar on May 20, 2026 at 4:00 PM EDT.

In this launch event PowerHour session with Matt Risinger and RDH Building Science, we will explore whether traditional cavity insulation strategies are missing the bigger picture. We will look at how thermal bridging, moisture management, and drying potential affect real-world wall performance, and why more projects are shifting toward exterior continuous insulation strategies.
Using PowerWool™ mineral wool insulation as a case study, we will review how vapor-open exterior insulation can simplify wall assemblies, improve durability, and reduce thermal bridging. We will also walk through practical jobsite applications and wall details builders are using today.
Whether you are designing high-performance buildings or just looking for smarter wall assemblies, this session will challenge conventional thinking and offer practical insights you can apply immediately.
Key Takeaways:
1. Understand the limits of cavity-only insulation. Learn how thermal bridging through framing and trapped moisture can affect the performance and durability of traditional insulated walls.
2. Explore the benefits of exterior continuous insulation. See how vapor-open mineral wool insulation can improve drying potential, reduce thermal bridging, and enhance overall wall performance.
3. Learn practical wall assembly strategies. Review real-world installation approaches and wall details that simplify construction while improving building durability and comfort.
