FDT Range Flush Floor Ducting for Pipework
FDT ducts for pipes fully comply with the water bylaws and BRE recommendations relating to the installation of pipes within solid floors. Embedded pipes are prone to leaks which can be difficult and expensive to rectify.

Thermal insulation can be achieved by the use of a proprietary slit tube pipe sleeve. Alternatively, where space is limited, the duct can simply be filled with loose-fill insulation.
Where pipes pass through a sound resisting floor, they should not be in contact with the duct, but should be surrounded by 25mm of insulating material. All gaps should be sealed.
A fire resistant barrier will be required where ducts pass through building compartments. An intumescent fire barrier is recommended.
Corners/Tees are supplied in a perforated 1250mm length to be separated on site. The 625mm legs can be placed together at a 90° angle to form a corner or overlapped at 180° to form a tee junction with a duct length butted to the aperture. Note the overall length of a tee junction will be 1250mm minus the width of the joining duct (not including flanges).
Stop Ends to suit duct size (ensure stop ends are fitted prior to screeding).
Butt Joint Plates optional to suit duct size.
