lightweight wall structures

Purpose of the work

Quantification and location of moisture penetration through leak-dependent creeping flows from the room into insulated, lightweight wall structures as a function of design, pressure differential, and leak position.

Method of approach

Pressure-dependent, high-precision through-flow measurement in a facade test stand and determination of the amount and distribution of condensate in a double climate chamber performed on lightweight wall sections with different cavity wall insulation and leak positioning.
