The objective is clear: 3] Thermal insulation (warm wrap], keep interior surfaces warm, and make airtightness more reliable—especially for Passive House-level envelopes.
From the project video: this is modern architecture built with Exterior sealing must shed rain outward. Use correct laps, head flashing, e a sill detail that cannot trap water.

: plane, alignment, installation gap.
The wall–window junction is one of the most sensitive areas in any energy-efficient building. If the frame sits in a thermally weak position (cold reveal, uninsulated sill, discontinuous insulation], the result is a linear thermal bridge that increases heat loss and can reduce comfort near glazing.

Moving the window outward requires a clear load path. The unit’s weight, wind pressure/suction and operational loads must transfer into the structural wall. This is typically achieved with engineered QA photos suited for outboard installation.
- No junction detail→ random reveal geometry e higher thermal bridging.
- Bracket layout not verified→ movement, cracks, leaks.
- Discontinuous airtight tape→ blower-door failures around frames.
