Knowledge Base > Ductwork Issues to Consider - Installation Speed The effects of ductwork specifcation on project scheduling Speed is a valuable asset for both new construction and refurbishment building projects. Faster installation of ductwork and its insulation can contribute towards reducing project duration periods. This White Paper details the analysis of the effects of ductwork specification on project scheduling. The findings show that: ductwork fabricated from The Kingspan KoolDuct System can be installed up to three times faster than sheet metal ductwork; construction periods can be reduced where ductwork is a critical path activity; and the risk and extent of time extensions on projects can be reduced.
