Most traditional ventilation products rely on foam-lining and baffles in the ducts to reduce noise, but these can reduce airflow. There is also the problem of build-up of dirt, dust and small insects in the pores of the foam, leading to loss of performance over time and the growth of bacteria and pathogens. The foam itself may also physically deteriorate.

The technology at the heart of Silenceair^® products eliminates the need for foam-linings and allows a much freer passage of air into your home.

Silenceair^® products are made from recyclable polypropylene, mixed with fire retardants and UV protectants and are virtually immune to environmental degradation.
