Clear answers
Frequently asked questions about ventilation grilles.
Your project may have different technical requirements. During the measurement you will receive advice for your specific situation.
Is a ventilation grille mandatory?
That depends on your construction or renovation project and the ventilation report. Have the requirements determined in advance by the competent specialist.
Does a grille make a lot of noise?
There are acoustic versions. The right choice depends on the environment and the required air supply.
Do ventilation grilles help against condensation and mold?
A continuous, correct air supply helps to remove moisture and can limit condensation and mold risk. The grille must be part of a well-designed and used ventilation system.
Are ventilation grilles energy efficient?
They ventilate without fully opening a window. Outside air still flows in, but self-regulating and correctly sized grilles help limit unnecessary air flows.
How do I maintain a ventilation grille?
Vacuum or clean the grille regularly according to product instructions. Keep the air opening clear and check whether controls and any filters still function smoothly.
