Case studies that
solve real problems.

During the insulation phase, the contractor faced issues with the insulation detaching from the GI ducts. Initially, this was perceived as a material defect or product quality complaint. The issue risked delaying the project timeline and compromising the ductwork's thermal efficiency and durability.

Insulation was being applied without following the proper installation guidelines, leading to poor bonding between the insulation and the GI ducts. Edge finishing and joint sealing were not executed as per standard practices.

Dry, dusty weather conditions are common in Riyadh. This means that standard insulation will not work under these harsh environmental conditions. This is because when glued with self-adhesive backing, it would not be sufficient to maintain a bond to the ducts due to dust and extreme dryness.

Factory-insulated PIR straight sections performed reliably. However, every field joint, valve, expansion bend, and plot take-off was insulated on-site using rigid PIR sections , a labour-intensive process prone to condensation, corrosion under insulation (CUI), and energy loss at fittings.

Mid-life re-insulation events were projected at years 10 and 20, driven by CUI at poorly sealed field joints. Total cost of ownership over 15 years under the all-rigid strategy was modelled at USD 138/m.
