CEILING-INTEGRATED COOKER HOODS

The discreet, efficient, and modern solution for your kitchen 

A ceiling-integrated cooker hood gives you the freedom to design a kitchen that feels open, spacious, and elegant—without visible technology drawing attention away from the overall design. At Thermex, we have been developing ceiling-integrated cooker hoods for decades and were among the first to introduce this type of extractor to the market. This means you get a solution that is thoroughly tested, technically mature, and designed to perform optimally in Nordic homes, where the demands for indoor climate and ventilation are particularly high. 

A good cooker hood is far more than a design choice. It is a key component of your indoor climate, removing grease, steam, and cooking odours to keep your kitchen clean and comfortable—both during and after cooking. Even in rooms with large windows, natural draughts are rarely sufficient, and especially in modern, airtight homes, proper extraction is essential to prevent negative pressure, condensation on windows, and poor air circulation.

Motor selection: 

The choice of motor has a significant impact on both performance and noise level. An internal motor is integrated directly into the cooker hood, making it easy to install. This solution is particularly well suited for short duct runs and for those who prefer a more traditional installation, where the entire system is located in one place. Modern internal motors are considerably quieter than earlier generations, and the combination of efficient grease filtration and strong extraction capacity makes them suitable for most homes. 

An external motor is installed outside the kitchen—typically in the loft, a utility room, on an exterior wall, or on the roof. This results in a noticeably lower noise level in the kitchen, as the motor itself is moved away from the living area. An external motor is also an excellent choice for larger homes, longer duct runs, or installations with multiple bends, where additional capacity is a clear advantage. Many choose this solution to combine high performance with maximum comfort. 

Ducted extraction to the outside or recirculation

When choosing a ceiling-integrated cooker hood, you need to decide whether the air should be vented out of the home or recirculated. Thermex always recommends ducted extraction to the outside, as this is the most effective solution. With ducted extraction, odours, grease, and moisture are completely removed from the home, contributing to a healthier indoor climate and more efficient kitchen ventilation. 

To achieve optimal performance, correct ducting is absolutely essential. The duct dimensions must always match the selected cooker hood and must never be reduced in size. Reducing the duct diameter significantly restricts airflow, effectively choking the extraction. As a result, the cooker hood cannot extract air efficiently, noise levels increase, and overall performance is reduced. For this reason, large duct diameters, as few bends as possible, and the use of rigid ducts and solid materials are recommended to ensure the best possible airflow. Thermex offers complete ducting solutions that make installation safe, efficient, and straightforward. 

In homes where ducted extraction to the outside is not possible, recirculation is a functional alternative. In this case, the air is passed through both a grease filter and a carbon filter, which effectively capture grease and bind odours before the air is returned to the room. The carbon filter is easy to replace when required. Recirculation is particularly suitable for apartments and homes where the building structure or ventilation conditions make ducted extraction difficult or impractical.

Ventilation ducts, installation, and accessories 
A ceiling-integrated cooker hood requires precise installation. The ducting must be correctly dimensioned, tightly sealed, and routed as directly as possible out of the house. This ensures both low noise levels and high extraction efficiency. Thermex offers all the necessary installation accessories, from complete ducting kits to mounting brackets, recirculation filters, and custom solutions for sloped ceilings. All our ceiling-integrated cooker hoods are designed so that a single technician can handle the installation, making the process faster and more straightforward for you as a customer.
