| #NO 12791 Conception de joints durables entre les fenetres et les murs.
Poor bonding details between a window (door) and the building shell cause many problems, the most significant of which are:
* rain penetration around the window;
* air infiltration or exfiltration around the window frame; and
* superficial condensation on the interior components of the window frame.
The problems stated above result in:
* a deterioration of interior finishes (peeling of paint and varnishes, lifting of floor finishes, mould, rotting, etc);
* a degradation of the building envelope components (corrosion of anchors, loss of structural properties for hygroscopic materials (wood, drywall), rotting of wood or rusting of steel);
* the presence of mould and a danger of infection for the occupants;
* a reduction in the thermal insulation properties of the materials, leading to greater energy consumption for heating and air conditioning;
* many drawbacks for the occupants of such a building (worry, frequent maintenance, discomfort, etc.); and
* an increase in the transmission of external noises towards the interior of he building due to the poor airtightness of the bond.
In general, the causes of the problems are mainly due to the design and production of the joints or the interface between the components. |
