Continuous ventilation.
Our continuous ventilation systems vouch for a comfortable indoor environment by means of constant airing with the windows closed. This keeps mould firmly at bay – with hardly any heat loss.

“Please do not specify windows for your home as a whole, but design them for each individual space.”


Cooking generates moisture, dirt and grease. Which is why kitchen surfaces should be hardwearing and easy to clean. Robust materials such as uPVC or aluminium are the perfect choice for windows. Or our extra-easy-care Cristal model with the window frame covered by glass.
The various opening actions allow your new kitchen window to be fine-tuned to the requirements of your kitchen units.

Above all through cooking, but also through washing, bathing and showering, through respiration or through our house plants. Regular ventilation regulates humidity, prevents mould growth and creates a comfortable indoor environment.
Whether for so-called shock (intermittent) or continuous trickle ventilation, kitchen windows need opening several times a day. This can be conveniently accommodated, for example, by our continuous ventilation options, summer/winter tilt hardware and sash limiter.

At a glance.
Kitchens generate moisture, heat and dirt. Designed for uncompromising quality, Finstral windows and doors are well able to handle this: their compact uPVC core guarantees the utmost durability – without any swelling or yellowing from hot steam. Intelligent, space-efficient solutions such as the sliding window offer an elegant answer to any clashes with the sink fittings. With the Twin coupled sash, the sunshades are safely housed between the panes. Everything from a single source.
The exhaust hood helps during cooking. Afterwards, a short burst of shock ventilation is needed! Fully open the kitchen window for 5 to 10 minutes. Refrain from leaving the window in the tilted position for hours on end as this will cool down the walls and increase the risk of mould.

A sliding window is a suitable option behind a sink. It is easy to slide open without obstruction by the tap. A kitchen window with a sublight can serve as an alternative: here, the tap is located in front of the fixed light, thus allowing unobstructed opening of the window sash.
In the kitchen, standard roller blinds and Venetian blinds are exposed to dirt and grease and thus demand a high degree of care. Exterior or interstitial sunshades are a more suitable option. Here, the roller or Venetian blind is automatically protected from soiling. With Finstral’s coupled windows, the Venetian or pleated blind is located in the sheltered gap between the panes. These privacy and solar protection solutions require accordingly little maintenance. For further details, please visit: Shading in sash - Finstral Planner.
