Regel-air® window rebate vents for PVC windows
Depending on the planned ventilation requirements, precisely controlled, medium and high air flow rates can be achieved. All Regel-air® window rebate vents and ventilation systems for PVC windows do not require any cut-outs in the window frame for air flow.
Regel-air® ventilation systems are maintenance-free and are suitable both for factory installation and for retrofitting to windows that have already been fitted. Most standard window systems can be fitted with or retrofitted with Regel-air® window rebate vents – even where space around the fittings is limited. Professional installation of our ventilation systems guarantees continuous air exchange and reliable dehumidification of the living space.
