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 requiring 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
