Window vents: the guarantee for a healthy indoor climate

With window vents or window ventilation, you bring fresh air into your home or building in a natural way via the dry zones such as the living room and bedroom. This advantage alone makes the investment worthwhile. Simply because using this method – in combination with a solid system for discharging polluted indoor air – you are guaranteed to benefit from healthy indoor air at all times. In addition, these ventilation grilles are installed so that they do not visually interfere with the overall appearance of your facade but do offer acoustic damping and help to avoid cross ventilation (or bilateral ventilation).

Fresh air at all times

The supply of fresh air – certainly in the new generation of window ventilation – is not random but rather very controlled. For example, the Renson's Invisivent Air and Comfort window ventilators (part of the C+ ventilation system) constantly make sure the right amount of fresh air is supplied in the home toegether with the smart Healthbox 3.0 discharge unit (the controller).  Moreover, they are equipped with an acoustic damping material and a self-regulating check valve, so that you can enjoy greater thermal comfort and energy-efficient ventilation.

Airtight and discreetly located

The Renson window ventilation louvres have been designed in such a way that they are concealed in the facade. They can also be aesthetically finished for indoors. In addition, they can be placed on the window, quickly and accurately, as one air tight entity. A ventilation system is mandatory for new constructions and thorough renovations – so why not opt for the very best window ventilation?

How do window vents work?

ventilation system type C removes dirty air away from wet areas (such as your bathroom or toilet) and out of your home, and brings fresh air into dry areas, such as your bedroom. The air supply comes from discrete Invisivent window vent louvres – an efficient solution that offers a few striking advantages. 

The benefits of window ventilation 

Many people choose to let fresh air into their home through a ventilation system using a natural air supply and window vents. And there are many good reasons to do so. Were you aware of these advantages already? 

  • You can enjoy a healthy indoor climate of the highest quality because the fresh air is always brought into your home directly and not via an air duct network. 

  • Window ventilation is the ideal solution for this in both new construction and renovation projects

  • The Renson-window vents come with soundproofing as standard. Do you live in a noisy environment? Then you can even opt for louvres with extra acoustic damping. 

  • It is a discreet, stylish solution to bring fresh air into your home. The louvres are almost invisible: we subtly hide them on the window in exactly the same colour as the window frames. 

  • A ventilation system that delivers natural air is the ultimate in energy efficiency because the movement of fresh air into the home does not require energy. In combination with a demand-driven mechanical exhaust system, the System C is the most energy-efficient system on the market. 

  • Over-ventilation is avoided thanks to the self-regulating flap in the window vent 

  • Thanks to the simple design, Renson window vent louvres are particularly maintenance-friendly
