Loading…Air exhaust materials
Air exhaust material is used for building, connecting and finishing ventilation and air extraction routes. Within this category, you will find materials for air ducts, roof terminals, ventilation grilles and matching fittings.
At Hewa, you will find air exhaust material for installers, service technicians, business customers and DIY users. When selecting the right material, check duct diameter, airflow, material type, connection size, terminal position, grille design, resistance, sealing and the complete layout of the ventilation system.

Air exhaust material for ventilation and extraction routes
Air exhaust material is used to extract, connect and route air outdoors in a controlled and neat way. A well-built route with matching pipes, terminals, grilles and fittings contributes to a reliable ventilation solution with lower air resistance, fewer leaks and cleaner finishing.
Selecting air exhaust material
The right choice depends on ventilation type, duct diameter, required airflow, duct route, roof or wall terminal and the required indoor or outdoor finish. With air extraction, it is important that all components fit together properly so the airflow is not unnecessarily restricted.
Within this category, also review ventilation pipe for air ducts, roof terminals for ventilation and ventilation grilles for air supply and extraction.
Important when choosing air exhaust material
- Check duct diameter, connection size and airflow of the ventilation system
- Technically match ventilation pipe, bends, fittings and grilles
- Check roof terminal, wall terminal, roof pitch, watertightness and wind load
- Limit sharp bends and unnecessary restrictions in the air route
- Check sealing, condensation risk, backdraft protection and free air passage
- Select grilles that match the indoor space, façade, roof or technical application
- Allow for maintenance, accessibility and cleaning of the duct route
Applications within air exhaust material
Ventilation pipe
For building air ducts between ventilation points, extraction points, grilles, terminals and technical installation components.
Roof terminal
For safely and watertightly routing ventilation air through the roof, taking roof type, diameter and finishing into account.
Ventilation grille
For air supply, air extraction and neat finishing of openings in façades, walls, ducts or ventilation connections.
Ventilation fitting
For connecting, reducing, sealing or finishing ventilation pipes and air exhaust ducts within the complete system.
Correctly matching duct, terminal and grille
An air exhaust route only works properly when diameter, duct route, terminal and grille match. An undersized diameter or too many bends can increase resistance, making the ventilation less effective. Open seams, poor sealing or incorrectly placed grilles can also affect air movement and noise level.
For installers, it is sensible to assess the complete air route in advance. Consider extraction point position, duct length, bends, roof terminal, condensation, backdraft, façade finish, service space and cleanability. A carefully built air exhaust system provides neater installation, more reliable operation and a lower risk of complaints about noise, draught or insufficient extraction.
Frequently asked questions about air exhaust material
What is included in air exhaust material?
Air exhaust material includes ventilation pipes, roof terminals, ventilation grilles, bends, reducers, connectors and fittings for air ducts.
Which air exhaust material do I need?
This depends on duct diameter, airflow, ventilation type, route length, terminal position and required finish. Always check the technical requirements of the ventilation system.
Why is the correct duct diameter important?
The correct duct diameter helps maintain sufficient air movement. An undersized diameter can cause extra resistance, noise and lower ventilation capacity.
What should I check with a roof terminal?
Check diameter, roof type, roof pitch, watertightness, wind load, condensate drainage, backdraft protection and connection to the ventilation duct.
What should an installer check during installation?
Check matching diameters, straight duct routes, limited bends, good sealing, firm mounting, free air passage, condensation risk, service space and correct roof or façade finishing.
