Industry: Buildings & Structures (BSTR)
Application: HEX-Heat Exchangers (HEX)
Substrate: Blown on Urethane insulation with waterproof mastic
Customer Location: Ivy League Medical School
Application Date: Summer 2004
Products: Belzona® 5131 (EG Cladding)
Problem: Original protection no longer water-tight. Insulation was wet and water was leaking into the building. CUI was feared.
- Degraded insulation on ducts
- Degraded insulation at building interface
- Recoated and protected with Belzona
- Summer 2007 still as good as new!
Heated and cooled air roof top ducts.
Application carried out in accordance with Belzona system Leaflet HEX-8
The original plan was to remove all wet existing insulation and re-insulate and waterproof over 200 feet of 60 inch carbon steel ducts.
Micro-porosity of Belzona system allowed existing insulation system to dry out so restoring protection and efficiency.
System still excellent 3 years on.
