The problem: whistling ducts and temperature chaos
Have you ever experienced a draft in one room while another feels airless? This is a classic sign of an unbalanced ventilation system. Without proper regulators, air flows where it is easiest – taking the shortest path and leaving the furthest rooms without fresh supply.
Another common annoyance is noise. When a system tries to "force" a large volume of air through poorly adjusted diffusers, an unpleasant whistling sound occurs. Additionally, unsealed ducts can let cold air and outdoor noise into your home when the system is off.
The transformation: silence and balance in every corner
Properly installed dampers create harmony. With IRIS regulators, every branch gets exactly the amount of air specified in the design. The bedroom air is fresh but you feel no movement, while the living room has enough oxygen even when guests gather.
Safety and energy savings become standard. Motorized dampers tightly seal outdoor channels when the unit stops, so heat does not escape outside in winter. Back-draft shutters ensure that neighbors' cooking smells from a shared ventilation shaft never reach your kitchen.
Save up to 15% on energy simply by balancing the system – do not heat excess airflow in rooms that do not need it, and avoid heat loss through leaky openings.
