Hallett Cove Shopping Centre

Project Overview

The Makris Group has significantly expanded Hallett Cove Shopping Centre, located in South Australia, to include a Big W supermarket and specialty shops incorporating a car park and landscaping. The development will help to improve local employment, community activity and strengthen the local economy by generating more opportunity for businesses.

Meeting NCC Requirements

Changes to the National Construction Code (NCC), aimed at improving the energy efficiency of commercial buildings, had to be considered by Hansen Yunken and Bestec Consultants when specifying the materials for this project. This impacted on the selection of insulation specified for the rigid ductwork insulation used in the HVAC system.

The minimum mandatory NCC Energy Efficiency provisions require the Total R-value of ductwork insulation to achieve a minimum requirement. The specific requirements are dependent on the climate zone, cooling capacity, and location of the system within the building.

Whereas traditionally a project such as this would have used 25mm R0.6 insulation for the rigid ductwork, Macey’s Insulation and Westside Mechanical used over 1000m2 of 38mm thick, FI22 Ductwrap™ on this project.

By using Fletcher Insulation FI22 Ductwrap™ at 38mm, Macey’s Insulation achieved a Total R-value of R1.25. This is calculated through the glasswool insulation providing a Material value of R1.1, and the reflec tive airspace, created by the Sisalation® facing foil, adding a further R0.15 to the Total R-value.

The Sisalation® facing foil also contributes to the integrity of the finished ductwork by providing a vapour barrier that prevents warm air from coming into contact with the outer surface of the sheet-metal and forming condensation.

FI22 Ductwrap™ was easily installed on the ductwork with Fletcher Insulation Vapastop® Foil Tape, a tough, reinforced tape coated with a high tack pressure sensitive adhesive.

Vapastop® Foil Tape is recommended for use with Sisalation® products to provide a vapour seal at joins.

Environmental Benefits

Fletcher Insulation’s range of glasswool duct insulation products provide significant benefits to the environment. By adopting the proven performance of glasswool insulation, you can be sure that the energy savings that are expected will be achieved, and by using less energy our buildings will reduce greenhouse gas emissions.

Fletcher Insulation glasswool is made using superior clean technology which represents a new era in green manufacturing. In addition, rainwater is captured and used in our manufacturing process and is then recycled. Our raw materials consist of approximately 80% recycled glass – much of which cannot be used in other processes and would otherwise go into landfill. Our plants are committed to operating in an environmentally sustainable fashion and have received accreditation to the environmental standard ISO 14000. Fletcher Insulation glasswool products have been recognised by Good Environmental Choice Australia (GECA) as being at the forefront in the area of sustainability. All Fletcher Insulation rigid duct insulation products meet the GreenStar insulant ODP emissions credit requirement, are low in VOC and safe to use in any application.

The Result

When balanced, the air conditioning system will deliver clean air to maintain constant temperature throughout the facility. With a proper maintenance schedule, the air conditioning system will continue to operate at its optimum efficiency to deliver comfort throughout its design life, providing a healthy environment for all building occupants.

Exacting specifications and tight construction windows required that the installation of the air handling ductwork go off without a hitch. The vastly experienced crew at Macey’s Insulation ensured that these requirements were adhered to and completed the contract in line with the expectations of Hansen Yunken.
