Note on RO Prep
Consideration of the window installation and wall as a system is important. The recommended method in these instructions and referenced elsewhere are intended to do just that. These details follow the concept that stopping air flow into the RO cavity will aid in managing water intrusion. Striving to form a continuous air barrier, water drainage plane, an insulation barrier, and a continuous vapor barrier is best practice; matching the window installation to the design of the actual wall system.
