System C
With system C, polluted air is mechanically extracted from rooms such as the kitchen, bathroom and toilet. Fresh air enters the home via ventilation grilles. A clear and widely used solution for residential construction and renovation.
A healthy indoor climate starts with the right system
Ventilation
A good ventilation system is essential for a healthy and comfortable indoor environment. Particularly in well-insulated homes, controlled air exchange ensures an adequate supply of fresh air and the removal of moisture, CO₂ and polluted air. Burgerhout offers complete ventilation solutions in which all components are seamlessly integrated.
What to consider with well-insulated homes
The importance of good ventilation
Modern homes are increasingly well insulated and built to be draught-proof. As a result, natural ventilation is limited and a well-designed ventilation system is becoming ever more important for comfort, health and energy performance.
Without adequate ventilation, moisture, CO₂ and polluted air remain in the home for longer. A good ventilation system prevents moisture and mould problems and contributes to a healthy indoor climate.
Good ventilation is therefore not an afterthought, but a fixed part of the installation. It ensures a healthy indoor climate, helps prevent moisture and mould problems, and maintains comfort levels, without unnecessary energy loss.
During the design phase, it is important to distinguish between airing and ventilating. Airing is temporary: opening windows or doors. Ventilation occurs continuously and in a controlled manner via a system that supplies and removes air day and night. In well-insulated homes, continuous ventilation is essential to prevent condensation, mould growth, and excessively high CO₂ levels.
A well-thought-out ventilation system ensures correct airflow, a stable indoor climate, and that the home remains comfortable and healthy in the long term.
Overview of the main ventilation systems
Ventilation systems at a glance
In well-insulated homes, a well-considered ventilation system is indispensable. Below is an overview of the most commonly used systems and their role in the overall air path. The choice of a ventilation system depends on the type of home, the degree of insulation and the desired level of control over the air flows.
System A – Natural Ventilation
When would you choose this? Existing homes where ventilation is entirely dependent on natural airflows.
Characteristic Simple system, but heavily reliant on weather conditions and user behaviour.
System B – Mechanical Feed
When would you choose this? Situations in which more control over the supply of fresh air is desired.
Characteristic Mechanical supply with natural exhaust.
System C – Mechanical Drainage
When would you choose this? Widely used in residential construction and renovation projects.
Characteristic Mechanical extraction in wet rooms, natural supply via grilles.
System D – Mechanical Ventilation with Heat Recovery
When would you choose this? Well-insulated new-build homes and energy-efficient renovations.
Characteristic Controlled supply and extract ventilation with heat recovery for a comfortable and energy-efficient indoor climate.

Our ventilation systems
Burgerhout focuses on the most commonly used ventilation systems in residential construction: System C and System D. From air distribution and ducts to dampers and penetrations: all components are designed to work together to ensure an efficient and reliable airflow path.
A good ventilation system is more than just a ventilation unit. Ducts, air distribution, valves and penetrations must be coordinated to achieve the correct airflows and system performance.

System D
With System D, air supply and extraction are fully mechanically controlled. Thanks to heat recovery, heat from the extracted air is used to pre-heat the supply air. This ensures comfort, a healthy indoor climate and an energy-efficient system.
Meeting standards is the baseline; correct application makes the difference
Ventilation in accordance with the applicable requirements
Good ventilation is not only important for comfort and health, but is also laid down by law. Clear requirements for air change, comfort and safety apply to ventilation systems. A correctly designed and installed system helps to meet these requirements.
In practice, it is often necessary to ventilate above these minimum requirements to prevent damp problems and a poor indoor climate.
What Burgerhout offers:
-
Products that meet the standards: All our ventilation systems, ducts and penetrations have been tested and certified in accordance with current European and national regulations.
-
Installation ease with certainty: Burgerhout Hybalans and Burgerhout EasyAir solutions are designed to enable installers to comply with regulations whilst maintaining a clear overview of the air flow path. This reduces the risk of errors and makes correct installation easier.
