Below is a colour palette offered by Sokółka Okna i Drzwi. Except the presented colours, it is also possible to colour the windows with any colour from the RAL palette.

At your request, windows from Sokółka Okna i Drzwi can be equipped with ventilators, which:
- regulate airflow proportionally to the relative humidity in the room,
- protect against mould,
- limit thermal losses, decreasing costs of heating,
- provide healthy, natural air inside the room,
- automatically optimize stream of the incoming air, depending on the ventilation needs,
- are functional in every climate, do not require power supply,
- are easy to fit on windows and on vertical blinds cartridges,
- are easy to maintain and aesthetic.


In respect of the principle of operation, we distinguish:


- Hygro-controlled ventilators (e.g. Aereco: EHA, EMM) - automatically controlled. The air flow stream depends on the steam content (relative humidity) inside the room, i.e. on air contamination resulting from the performed actions, such as washing, cooking, drying, etc. The control sensor is polyamide tape, which upon change in the relative air humidity changes its length, which causes smaller or greater opening of the damper, this letting more or less air into the room. The ventilators operate within the range of 35 to 70% relative humidity. If humidity in the room is lower or equal 35%, the ventilator is shut and minimum amount of air gets into the room. With increase in humidity, the ventilator opens and at 70% or more, it reaches maximum capacity.



- manually-controlled ventilators (e.g. Ventair) - the user regulates the opening of the ventilator, thus adjusting quantity of supplied air. Position of the ventilator damper is changed manually.
