ABSTRACT
The subject of this study is experimenting with a procedure to verify a prototype walkable
glazing module in the laboratories belonging to the University of Žilina. A square-shaped
specimen with sides of length 800 mm, incorporating a triple-glazed insulated glass unit within
a thermally broken stainless-steel frame, was conditioned and tested under rigorously controlled
conditions. Air permeability was assessed following EN 1026 and EN 12207 by mounting
the specimen in a special sealed test frame, applying stepwise pressure differentials up to
600 Pa, and recording steady-state volumetric flow rates. Watertightness testing conformed
to EN 1027/EN 12208 protocols, using an oscillating rain simulator delivering 5 L/m2·min
and internal pressurization in incremental steps, with leak detection via absorbent-paper
inspection. For completeness, the measurements were supplemented by thermal-transmittance
evaluations as per the ISO 12567-2 employed hot-box method. The measurement results showed
that the product is capable of withstanding several extreme weather conditions.
