What is the difference between an air vent cover and an air valve?
Ventilation What is the difference between an air vent cover and an air valve?
An air vent cover and an air valve seem, at first glance, to do the same thing: they let air in or out of a specific space, such as your home. Yet they are two very different products, each with its own place and function. In this blog, we'll first show you the visual difference, and then get to the heart of the matter: when do you use an air vent cover, and when do you use an air valve?

What is demand-controlled ventilation?
Ventilation What is demand-controlled ventilation?
Demand-controlled ventilation automatically adjusts based on the air quality in your home. It ventilates more when needed and less when it isn't. The result: a healthy indoor climate and lower energy consumption, without any effort on your part. In 2026, demand-controlled ventilation is the standard in modern mechanical ventilation systems and heat recovery units. In this blog, you'll find everything you need to know about demand-controlled ventilation and which products from our range are suitable!

What is smart ventilation?
Ventilation What is smart ventilation?
Smart devices are becoming increasingly common in homes. We control our lighting, thermostat and security systems easily via an app or with voice commands. Ventilation, however, often receives less attention, even though fresh air is essential for a healthy indoor climate. Fortunately, there are now ventilation products that can be fully integrated into your smart home. Smart ventilation means that the system operates automatically based on air quality, humidity, occupancy or schedules. It reduces manual effort, improves living comfort and makes ventilation much more efficient. In this blog, we explain what smart ventilation is, what you need for it and which products from the Ventilationland range are already suitable for app or sensor control.

How can I reduce the noise of my ventilation system?
Ventilation How can I reduce the noise of my ventilation system?
It is important to know where noise in your ventilation system is coming from, before you can reduce it. A ventilation system causes air to be moved and in doing so, vibrations are released. To do this, a mechanical ventilation system is equipped with a motor that also creates vibrations. Many of these vibrations produce noise and thus annoyance. The noise level can vary from one ventilation system to another.

What is an MVHR unit? Energy-efficient ventilation
Ventilation What is an MVHR unit? Energy-efficient ventilation
The abbreviation MVHR stands for heat recovery and is a method of ventilation in which as little heat as possible is lost. With MVHR ventilation, the used, warm air is simply removed and its heat is transferred to the fresh, cold air that flows through the ventilation system into the house. An MVHR unit keeps the air flows in your home balanced, which is why it is also known as balanced ventilation. The system is also known as 'ventilation system D'.
