A solution for maximum air tightness
This allows the box to be fully plastered on the inside and hermetically sealed. If insect protection is not required, the opening is closed with an aerodynamic clip-on PVC opening cover.
This simplifies installation, as there is no longer any need to fix screws to the subframe. The two-part guide rails can be plastered over, which means that even when covered by the façade they still allow the system to be dismantled. For divided elements, standard guide rails are brought to the required dimensions with a double cross-section.
