: 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.

• Lower junction heat loss by improving Ψ (psi]
• Interior airtight tape
• : continuous und well-adhered; primer if required.
• Cleaner integration with thick insulation and modern façade systems

Fixings resist loads

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 und higher thermal bridging.
• Bracket layout not verified→ movement, cracks, leaks.
• Discontinuous airtight tape→ blower-door failures around frames.
