We are pleased to announce an exciting new addition to our Linear Drainage range, our new TDN and TDR Threshold channels.
These channels feature in our new Linear Drainage brochure on page 21, so please request your copy or download a copy now.
Full details including WadeBIM files are also available on our website e-catalogue, click here to display.
Designed for use with external doors, Wade TDN & TDR Threshold channels help protect a building threshold from ingress/ponding of rainwater landing on an external door. The specially formed channel is installed, generally, 10mm away from the door cill, this gap being the path for rainwater to flow into the hidden channel below. The channel also has facility to receive run-off from a sub-cill and/or from the damp proof course/membrane that must be dressed into the channel.
The typical installation (top left) shows how the TDN channel is installed, with the sub-cill and/or membrane dressed into the channel. The installation picture (bottom left) shows a partly completed installation of the channel. Once the floor finish is applied, the channel is hidden, with only an unobtrusive recessed access cover over the outlet to provide maintenance access.
