Multi-Million Dollar Renovation of RLI Corporate Headquarters

Project Summary

When RLI Corp. set out on the multi-million dollar renovation of its corporate headquarters, it wanted to create a light and open space which would inspire employees for years to come. This meant reviewing every aspect of the existing facility, including raising ceiling heights in the offices. With conventional ductwork systems this would have been difficult to achieve but the flush installation of The Kingspan KoolDuct® System made it a breeze.

The speciality insurance company has been based in Peoria, Illinois for almost 50 years and its 1970’s building was ready for a transformation into a state of the art corporate headquarters. A stepped refit was overseen by Mangieri Companies, Inc. over 16 months, transforming the building both inside and out and creating new open employee collaboration and meeting spaces, including an employee gym.

As part of the open plan interior, Dewberry looked to the raise ceilings by reducing the existing ductwork, heating, cooling and sprinkler services space closer to the roof above a suspended ceiling. To achieve this, Delta Air Systems LLC furnished low and medium pressure ductwork panels using The Kingspan KoolDuct® System. The ductwork was fabricated and was able to be installed flush to the ceiling by The PIPCO Companies Ltd. The Kingspan KoolDuct System’s premium performance rigid thermoset phenolic insulation core ensured it met the require R-value of R-6.0 Ft2.hr.oF/Btu, within the reduced space requirements.

PIPCO can attest to the value of The Kingspan KoolDuct® System. In addition to allowing greater ceiling heights in the renovated building, the pre-insulated design of the product meant that the fit out was completed very quickly, with increased safety and reduced installation costs. KoolDuct’s adaptability to support changes and field adjustments also resulted in less modifications and cost with other less flexible infrastructure requirements. - PIPCO.

The Kingspan KoolDuct® System can be installed in a single fix and is available in lengths up to 13 ft. Independent research has shown that it can consistently reduce installation costs when compared with galvanized sheet metal ductwork insulated with fiber glass duct wrap. The System produces pre-insulated ductwork where the air-leakage rate can be reduced to a fraction of that typical of sheet metal ductwork and can easily achieve SMACNA air-leakage Class 3, delivering further cost savings across the lifespan of the building through reduced energy consumption.

Ductwork fabricated from The Kingspan KoolDuct® System is UL Listed as a Class 1 Air Duct, to Standard for Safety UL 181 (Factory Made Air Ducts & Air Connectors), when fabricated to a specification clearly defined by UL.
