Ductwork Summary

Ductwork and Weight

The effects of ductwork weight on project feasibility

Low weight insulated HVAC ductwork can incur numerous diverse benefits on a building project, particularly refurbishment / retrofit projects. Benefits include:
  • Easier installation and much lower associated handling costs
  • Reducing the risk of exceeding the maximum manual handling and lifting limits for an individual in the workplace, as recommended by many health and safety regulatory authorities
  • Reducing the requirement for specialized mechanical handling and lifting equipment
  • Installing lighter supports at smaller centers
  • Alleviating the requirement for additional structural support in buildings undergoing renovation
The findings of an analysis of the weights of differing insulated HVAC ductwork specifications, both designed to meet the same US performance standards, show that ductwork fabricated from The Kingspan KoolDuct System can weigh up to 72% less than ductwork constructed from galvanized sheet steel insulated with glass fiber duct wrap.
Kingspan Insulation commissioned a separate review of six UK case studies by independent consultants, Rider Levett Bucknall. The purpose of the review was to examine: insulated sheet steel ductwork and ductwork fabricated from The Kingspan KoolDuct System; their relative performance with regards to weight; and the benefits that this can occur.
The findings from the analysis of the effects of ductwork weight on project feasibility show that:
  • The introduction of the Kingspan KoolDuct System to a project can save money and add value
  • It provides the only practicable solution for some projects
  • Can function to ensure project viability
It is clear that, as a result of the findings described above, The Kingspan KoolDuct System should be considered the product of choice for insulated HVAC ductwork systems where weight is a key requirement.
