PowerHour: The 4 Control Layers
PowerHour by PowerWool™
The 4 Control Layers: Water. Air. Thermal. Vapor.
Which matters most, and where do they belong?
Join us for a webinar on Apr 30, 2026 at 4:00 PM EDT.

Join us for the first-ever PowerHour by PowerWool™, a focused building science session breaking down the four essential control layers every high-performance building depends on.
We’ll cover:
Water Control – The top priority. If bulk water is not managed first, nothing else matters.
Air Control – The biggest mover of moisture and energy loss. Continuity is everything.
Thermal Control – Continuous insulation, thermal bridging, and dew point positioning.
Vapor Control – When it is needed, when it is not, and how drying potential changes the equation.
We will clarify which layers are truly non-negotiable, how they interact, and where each belongs within the wall assembly.
Practical. Technical. No fluff.
One hour that will change how you think about envelope design.
