Standard INSUduct can take up to two 25mm diameter PE pipe (including barrier pipe)
or one 32mm diameter (including barrier pipe) by removing the insulation through the centre of the product.
Please note that Groundbreaker installation can be made before or after the installation of INSUduct.
For ‘climbing’ INSUduct, repeat instructions rising up the face of the building (Bellmouth Fitting).
The fixing instructions below have been compiled after consultation with representatives of the UK water industry and will ensure compliance with Water Regulations, failure to observe the instructions or to reduce the thickness of insulation may cause the apparatus to freeze in severe weather and cause damage to the product, if in any doubt, please contact your local water company.
Images below indicate fixing options please also refer to installation instructions.
We recommend a 90mm duct through the wall with a minimum of 38mm insulation all around the pipe and extended into the concentric locating lugs on the back of Groundbreaker. Our SHalloduct product will ensure compliance, please refer to our technical page.
