profi-air heat recovery ventilation

What does heat recovery ventilation (HRV) stand for?
Heat recovery ventilation is mechanical ventilation of residential buildings and apartments.

Do I really need it?
Healthy air, effective building protection, stable value of property and the improvement of energy efficiency are just some of the HRV’s benefits.

What does it have to do with starline design grills?
The starline design grills are part of our profi-air complete system for heat recovery ventilation. The ventilation grills are the only visible elements of an HRV system in the room. This is one of the main reasons why we attach great value to versatile designs and high-quality materials.
