Window ventilation via a slot grille is a great alternative for home ventilation. To begin with, clean air in the house is essential for health. Insufficient or poor ventilation results in air quality deteriorating to the point that it may lead to respiratory complaints such as coughing and sneezing. That is why it is important to ventilate a house properly, including via windows or frames. The advantage is that the grilles do not disturb the wall or glass surface, which is generally considered more aesthetically pleasing.
Ventilation through the window or frame wood by means of a thin, long grille is called slot ventilation. A slot is milled into the frame, and the slot grille is installed onto or partly into it. When the grille is open, the space is ventilated via the slot grille. The inner grille is usually adjustable to complete closure. There is a choice of various slot grilles, made of different materials: aluminium, stainless steel and plastic.
In our range we carry ventilation grilles from the brands Fresh, Rotary and TiKu. Fresh grilles are reliable and available in different sizes and ventilation capacities. For example, the Fresh 101. Various flow-through grilles from Fresh are also available. The Rotary brand includes the SM1400 series. This aluminium slot grille is infinitely and silently adjustable, and can also be supplied with a remote control rod. Rotary slot grilles are available in different lengths. More information about these brands can be found on the product pages.
