Ventilation louvres

Ventilation louvres for a better indoor climate

Ventilation louvres 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.

What is a ventilation louvre?

A ventilation louvre is a louvre in a window, door or wall that allows fresh air to enter and polluted air to exit.
Louvres are an indispensable part of every ventilation system. In a well-insulated, airtight home, ventilation louvres are the only way for fresh air to enter the home.

How does a ventilation louvre work?

Ventilation louvres use outdoor air to ventilate your home. Fresh air enters the home via these louvres, while polluted indoor air is extracted via a fan. That way, a constant flow of air is established, passing from room to room via gaps under the interior doors or ventilation louvres in the walls or doors.

Ventilation louvres for natural ventilation

Natural ventilation does not use mechanical fans, so fresh outdoor air needs to be able to enter the home via ventilation louvres.
To make sure it can do so, you can choose between inconspicuous window vents or wall louvres. That way, your living space is 'flushed' by fresh outdoor air all day long.

What are the benefits of ventilation louvres?

Polluted indoor air often struggles to find its way out of modern, well-insulated homes. Fresh outdoor air, on the other hand, struggles to get in. Ventilation louvres form the connection between the inside and the outside — and in doing so, they help improve the air quality indoors. That instantly offers several practical benefits:

  • Damp issues or mould in the home can cause serious damage to both your property and your health.
    Ventilation louvres help extract humid air and allow dry air to flow in.
  • Ventilation louvres enable a natural flow of air, meaning you don't have to put up with the noise of fans spinning all day.
    If you live in a noisy environment, we also offer ventilation louvres with acoustic damping.
  • No spinning fans also means no energy consumption. As such, natural ventilation is an energy-efficient solution for healthy indoor air.


Are there any downsides to ventilation louvres?

When you open a window, you invite in draughts, insects and noise. You might think the same applies with a ventilation louvre — but that's not the case with Renson.
Insect-proof, acoustic damping or other features — our wide range of ventilation louvres is bound to contain a suitable model for you.

Ventilation louvres for different applications

Ventilation louvres for different applications

Night cooling to wake up fresh in the morning

Did you know that ventilation louvres also contribute to keeping your home cool in summer? When combined with screens, they can keep the indoor temperature under control. The screens prevent too much heat building up in your home during the day. Night cooling louvres flush your home with cooler outdoor air at night to get the mercury down by a few more degrees. And unlike an open window, insects and burglars don't stand a chance of getting in.

Maintaining your ventilation louvres

Over time, dust and dirt might accumulate on and in your ventilation louvres. This can prevent the air from flowing through freely, resulting in less effective ventilation. Fortunately, cleaning your louvres is easy. Simply vacuum them and wipe them clean with a damp cloth once a year.
