Adequate domestic ventilation is essential to prevent build-up of condensation in your property.
Sydenhams can offer a range of ducting and fan systems that can be used throughout the house. A typical example would be a 4" fan and ducting system to vent an internal bathroom which can have a pull, timer or humidistat switch depending on the requirements.
There are many other products available for different purposes, some of which are listed below. For more information, please contact your local branch.
