Ducts can be supported from below or from above the duct using a hanging arrangement, Roof-Pro frame selection is influenced by which method of bracket is employed.

In order to advise on product selection Roof-Pro will require:
Duct information such as:
dimensions, target height above roof level, insulation thickness and type, intended centers of support.
Standard requirements of the roofing assembly construction:
deck type, insulation thickness, type of insulation, the waterproofing membrane type and both insulation and waterproofing manufactures details.

Ducts that suit the TAB-D profile can be supported by the TAB-D-500, 750 or 1000 range. ( including insulation, max width 1000mm, maximum height to the top of the duct at the lowest part of the roof 1000mm ). With the TAB-D range the duct is supported at target height by the lower connecting beam and clamped by the upper connecting beam.
