The Effects of Ductwork Weight on Project Feasibility
Research by independent consultants Bucknall Asutin* into a selection of refurbishment
projects has shown that the main reason for choosing the Kingspan KoolDuct System was that it could overcome severe constraints on structural loadings.
In these circumstances the selection of the Kingspan KoolDuct System,
over a galvanised sheet steel ductwork system, was often the only realistic
choice the alternative normally being the introduction, at potentially significant additional
cost, of secondary steel supports to transfer service loads back to the
structure. In some projects even this option was not available e.g. where
buildings contained listed features that could not be obscured by the introduction
of new structural members.

* Research carried out by Bucknall Austin on the Kingspan KoolDuct® System was conducted on the 22 mm thick panel and the aluminium grip flange. Kingspan Insulation is currently revisiting this research for the 33 mm thick panel and the new 4-bolt flange.
