Ducting

The type and size of duct used depends on its position within the system and other considerations such as acoustic performance. Ubbink's design service determines the most appropriate product and will determine the diameter of ducting requred. Options include:             Uninsulated Ducting Standard ducting is available in 100mm, 125mm and 150mm diamters and can be used for all ducts running below insulated loft spaces including those requireing up to 1 hour fire resistance.                     Insulated Ducting Insulated ducting is available in 100mm, 125mm and 150mm and is used within insulated loft areas to reduce the danger of condensation.                     Acoustic Ducting This ducting has been specifically designed to provide a solution to transmitted noise into or from ventilated areas.

Extract Valves

Extract Valves - Standard The standard extract valve is constructed from white polyamid and polypropylene and has a 'plug-in' fixing frame giving easy access for cleaning or adjustment                     Extract Valves - Humidity Controlled Humidity controlled valves optimise performance by naturally regulating airflow according to occupier demand. Sensors within the valve automatically detect when ventilation is required and modulate as the internal air relative humidity varies between 35-70% thus providing controlled ventilation
