Description
Insulated duct:
Insulated duct available in 1 m or 2 m lengths. Each
length comes complete with a single duct to duct
connector (GD833SSCI) to fit into the next straight
length of duct. Suitable for use with GD813 ø 125 mm
PVC ductwork.

The Zehnder ø 125 mm self-seal insulated ducting is perfect for meeting Building Regulations for insulation whilst
minimising air leakage. The lightweight and robust ductwork along with the self-seal connection mean this can be
installed much faster than conventional rockwool insulation.
The PUSH - CLICK - LOCK connection eliminate the need for tape, sealant and screws and also exceeds the
requirements set out in DW/143 Class A Leakage Test and DW/154 ductwork standards and has also been
independently tested by the BRE.
The ductwork is compatible with our standard ø 125 mm PVC ductwork.
