Wasted Heat and Dripping Condensation
Picture a harsh winter day: your heat recovery unit is working hard, extracting heat from the exhaust air, but all that warmed fresh air travels through uninsulated ducts in a cold attic. By the time the air reaches your bedroom, it has already cooled down, forcing your heating system to work twice as hard to compensate for the loss.
Heat loss is only half the problem. When warm indoor air flows through cold ducts, the temperature difference creates a dew point. Condensation begins to gather on the outside or inside of the metal pipes. Water droplets damage plasterboard ceilings, cause mold, and can eventually ruin the expensive components of your ventilation unit.
Warm Homes and System Longevity
Proper insulation turns these risks into a thing of the past. When ducts are professionally insulated, the heat stays exactly where it should – inside the pipe. The air temperature does not drop even across long runs, meaning your diffusers supply pleasantly warm, rather than chilly, air.
Insulation also acts as a powerful sound dampener. Standard metal ducts are excellent at transmitting the hum of the recovery unit's motor and the rush of airflow. By wrapping them in high-quality insulation, vibrations are absorbed, ensuring absolute silence in your home at night, even when the ventilation system runs at maximum speed.
Protects against condensation and mold – a properly selected insulation thickness guarantees that moisture will not accumulate on the ducts or within your home's structures.
