Window vents

Enjoy fresh air indoors with window vents

With window vents, you can ensure a constant and natural supply of fresh air into your home through dry rooms such as living rooms and bedrooms. Our window vents are subtly integrated into your façade — and their acoustic damping comes as a bonus. If you still think opening a window is the best way to ventilate, think again. 

How do window vents work?

The new generation of window vents supply fresh air in a controlled manner. The self-regulating non-return valve prevents annoying chilly draughts, while the window vent itself is also designed for improved acoustic comfort. The Invisivent® Air and Comfort window vents by Renson® are controlled by the smart Healthbox 3.0 ventilation system to keep your home ventilated effectively and energy-efficiently.

Improving your health through window vents

Extract polluted, humid indoor air and draw in fresh outdoor air: those are the fundamentals for a healthy indoor climate. Healthy indoor air helps prevent damp issues around the home — and mold, in the worst case scenario — and that in turn can help you avoid potential symptoms such as a sore throat, blocked nose, coughing and sneezing, or even a tight chest. The fresh air brought in via your window vents helps drive out damp and keeps your property and body healthy.

Improving your health through window vents

Enjoy fresh air and save energy with window vents

Your window vents flush your home with fresh outdoor air to improve your indoor air quality. They do so in a highly energy-efficient way, as this natural supply of air does not use any electrically powered elements. On top of that, the exact volume of fresh air that's supplied always remains under control: the self-regulating non-return valve prevents too much cold outdoor air from entering your home, so you never have to crank up the heating. In other words: window vents keep your home ventilated effectively and energy-efficiently.

What are the advantages of window vents?

A healthy indoor climate without energy consumption and without imposing louvres: those are just a few of the advantages. But it doesn't stop there: window vents also offer several other surprising, useful, and above all, enjoyable benefits. 

  • Window vents are the ideal solution for both newbuild and renovation projects.
  • The near-invisible window louvres allow fresh air to enter your home, while being discretely and stylishly integrated into your façade. By matching their color to your window profiles, a subtle result is guaranteed. 
  • Their simple and clever design makes window vents extremely easy to maintain. That way, you get to enjoy healthy indoor air with even less hassle. 

Ventilation louvres

Ventilation louvres on your windows, doors or in the walls help you keep your house healthy. In a well-insulated house, they are the perfect way out for polluted indoor air, while also allowing fresh outdoor air to enter. Ventilation louvres guarantee proper air circulation and can help prevent damp problems — and their consequences — in your home.

Window vents and a mechanical ventilation system 

Want to get the maximum effect out of your window vents? Combine them with a demand-driven exhaust ventilation system, such as Renson®'s Healthbox 3.0. The natural supply of air supports the mechanical extraction of polluted indoor air via your wet rooms. That way, you're guaranteed exactly the right level of fresh air at all times, in every room around your home.

Window vent maintenance

If you are relying on a natural supply of fresh air, it's worth noting that dust and dirt may start accumulating on and in your window vents. 
To guarantee a constant and optimal flow of air, you should clean your louvres annually. 
This also applies when you combine window vents with extraction via an exhaust ventilation system.
