Doors are one of the most frequently used items in controlled storage and sterile environments. It is important that access points comply with refrigeration guidelines set out in the ASHRAE handbook, covering refrigeration equipment and systems for applications other than human comfort.

Carona Group’s 4500 and 5000 Series Thermal Traffic & Personnel Access Doors are designed to provide highly effective barriers to temperature and air movement. The integration of santoprene gaskets of Carona Group’s 4500 Thermal Traffic Doors ensures energy efficiency and hygiene control.

Leroy Palmer Consulting Engineers have supervised tests measuring the energy lost through Coldshield’s4500 Series Thermal Traffic Doors and the energy lost through Coldshield’s2400 Series Flexible PVC Swing Doors. The results of these tests were used to compare the efficiency of the two types of doors. The tests measured how much power was required to maintain constant temperatures in two conditioned spaces. On average Coldshield, 4500 Series Thermal Traffic Doors used 20.8% less power than the 2400 Series PVC Swing Doors, making them a highly effective barrier to temperature and air movement.

Serial numbers are given to all doors. This means that components are easily traceable and replaced should they need to be. As such, when points of leakage are detected, problems can be resolved swiftly.




Methylene diphenyldiisocyanate (MDI) and Toluene Diisocyanate (TDI) are common chemicals in producing polyurethane foams. MDI and TDI in their liquid form as precursors to urethane production may present danger of serious damage to health by prolonged exposure. Precautions for workers such as reducing skin contact, inhalation of vapours and using appropriate Personal Protective Equipment (PPE) mitigate potential issues to low risk in accordance with an ecospecifier Risk Assessment. Refer to Material Safety Data Sheet for further information.

Once the product has cured, the MDI has undergone a chemical reaction, resulting in inert polyurethane that poses no known health issues as an installed product. However, Ecospecifier strongly recommends the production of the foams should be conducted within a closely controlled environment with appropriate personal protection equipment on at all times.


This product will aid the reduction of thermal heat transmitted into and out from buildings and thermally controlled areas, greatly improving internal thermal comfort levels through the reduction of heat that is allowed to escape or enter buildings and internal areas.

Emissions – There are no known emissions to terrestrial environments.

PhysicalProduct contains aluminium. The production of alumina from bauxite ores uses a chemical treatment, known as the Bayer Process. The alkaline mist associated with this process may have adverse land and vegetation impacts.


Emissions –MDI and TDI are routinely transported in large quantities without spillage. However, in the event of a spill into the aquatic or terrestrial environment, it has to be reported to the local government as polyurea compounds are insoluble and non-biodegradable.

Physical – The petrochemical portion of polyethylene can potentially result in sea pollution from the extraction of oil. Other aquatic emissions include methanol and butane in the production of ethylene (Source - Life Cycle Assessment of PVC and of principal competing materials, Final Report, commissioned by the European Union, July 2004).


Greenhouse gas (GHG) – These doors utilize virgin plastics which are fabricated from fossil fuels. Fossil fuels generate both atmospheric pollutants and greenhouse gasses on combustion. However through reducing unwanted energy transfer, air conditioning/refrigeration or heating loads, greenhouse gases produced by the building may be reduced.

Operational efficiency – The thermal benefits generated by this product may contribute to improved operational efficiency and reduced operating costs.

Re-use Efficiency – Product can be reused, re-located and recycled at end of life.

Toxics and Pollutants – Polyethylene is highly stable and does not readily react with other elements or compounds in the environment.

Ozone Depletion – Not Applicable.

Urban Heat Island Effects – Not Applicable.

Noise – Not Applicable.


Petroleum, the primary raw material of polypropylene and polyethylene, can have localised marine biodiversity impacts in its extraction and potentially catastrophic impacts when spills occur.

Recycling can reduce use of virgin resources which can reduce impacts on biodiversity. Reduction of waste to landfill can reduce land required for waste disposal which can have impacts on biodiversity.



Resource Efficiency

It is a long life product that can be recycled at end of life. Thus, it lowers carbon footprint for materials and manufacturing.

Embodied Fossil Fuel Energy

Carona 4500 Series Personal Access Doors have an embodied energy of 3827MJ / Door*

Carona 5000 Series Thermal Traffic Doors have an embodied energy of 3758MJ / Door*

Embodied Water


Polyethylene is a highly durable material with a long life expectancy. This is backed by the product’s 10 year warranty. Exact period has not been substantiated.


Carona Group Pty Ltd is involved in the reuse and recycling of their door components. They offer a service to customers to remove any old doors that are being replaced for return to their factory for dismantling.


All major parts are repairable. Serial numbers are given to all Thermal Traffic & Personnel Access Door components. This means that components are easily traceable and replaced should there be a need to do so.

Design for Dematerialisation


Design for Disassembly

All parts can be disassembled.


Carona Group Pty Ltd is involved in reuse and recycling of their door components. Carona Group’s packaging for onsite installations is 100% recycled and is manufactured from recycled cloths. Despatched orders for large door orders are packaged into plantation timber crates with recycled cardboard base and lid to reduce our timber usage.


The doors are sorted into the categories as follows:

Approx % by weight

1. Reusable or re-workable parts: 7%

2. Recyclable materials (Aluminium, Brass and Steel): 50%

3. Materials suitable for packaging: 5%

4. Landfill waste: 38%



Carona Thermal Traffic & Personnel Access Doors are designed and built to be maintenance-free.

Product Takeback Scheme

On installation of Thermal Traffic & Personal Access Doors, Carona Pty Ltd will remove from site the existing doors and return to a manufacturing facility for recycling/reuse.
