Integrated night vent.
The night vent is standard for lift-slide systems. This allows
for an efficient night vent with optimal air exchange
at any time simply by using the handle.
With motorised operation, the night vent can even be
programmed to allow the sash to close of its own accord.
Minimum operating force, maximum ease of use.
There is always a magic word for maximum ease of use.
When it comes to lift-slide systems, this is "energy storage".
A special spring hidden in the comfort gear uses the
weight of the sash to lift it even more easily.
The positive control is decisive for larger parallel slide & tilt
doors: merely turning the handle moves the sash conveniently
into the desired position.
Innovative product details.
With a whole range of big and small innovations, PORTAL
has driven the sliding technology on the market and set
new standards. Our cube design of the new covers is a good
and current example of the elegant design of lift-slide systems.
Small, flat, without visible screwing and matching the
handle colour, the new covers ensure the matching accents.
Furthermore, they can be combined with the no longer
visible STOP axxent door stopper.
