When a 1979 Chicago area cold-storage warehouse needed a roof upgrade, Polyiso insulation was a critical component of the new roof system.
Owned by CenterPoint Properties, the largest owner/developer of industrial real estate in the greater Chicago area, the building required a roof system that replaced the15 year old 236,000-square-foot BUR roof system with efficiency and longevity in mind.
The old roofing system leaked, including at the drains and field seams. The roof had overlay work from several past repairs and an uneven surface with obsolete mechanical units, which were removed.
The building is located in Hodgkins, Ill., where the tenant, Fresh Logistics, consolidates daily rail shipments of produce from key agricultural areas in California and Washington for distribution. Along with the new roof, an efficient and consistent temperature-controlled facility was critical to Fresh Logistics daily operations.
After the existing roof was torn off, two staggered layers of 2” Polyiso insulation, was topped with 60-mil energy efficient TPO (thermoplastic polyolefin) membrane. This system allowed the contractor to use 70 percent fewer seams than the previous roof.
The roof system offers a cost-effective solution that provides a flat, clean, energy efficient roofing solution. Since the building has a temperature-controlled environment, the reflectivity of the 60-mil TPO keeps the building cooler and the four inches of insulation provide the proper R-value.
The roof was installed by Northcross Roofing and Waterproofing, Inc.
