ECOSPECIFIER LIFE-CYCLE ASSESSMENT

INTEGRATED DESIGN AND POLICY ISSUES

Product is designed to replace fibre-based, wool-based, blanket and vapour barrier in one application. Product performs as a thermal insulation, vapour barrier and can be used as a thermal break.

Thermal performance is fairly dependent on minimum air space dimensions (preferably over 20mm) adjacent to the outer surfaces and installation context. Reflective and hybrid insulation values should be quoted in the context of the building element as it is not the material itself which provides the thermal resistance but the impact of the low emittance surface that reduces heat flows across an air space.

It is important that penetrations through the foil (e.g. plumbing pipes or electrical cables) are taped and that the joins in the foil are taped. If air can leak from one air space to the next, the heat flow by convection ‘short circuits’ the reduced radiant heat flow caused by the reflective foil, substantially reducing its effect.

Reducing heating and cooling loads of buildings contributes to reductions in energy consumption and associated greenhouse gas emissions, through reduced need for air conditioning, and hence reduced plant size and operating costs. Reduced re-radiation from surfaces exposed to direct sun will also support staff comfort and increase productivity

 

HUMAN HEALTH

Health

Products are manufactured with safe polymer polyethylene without the use of formaldehyde (as some fibreglass and wool products are). As such, the products are able to provide energy efficiency without creating human health risks associated with airborne fibres or VOC emissions.

If apply, anti corrosion, or, antiglare coatings contain a very small percentage (1/1000 of a gram per m2) of chemicals which in its raw form prior to manufacture is hazardous. However, after the ink is applied the product passes through a lamination process at approx 250°C which disperses this solvent, therefore there is no further odour or off-gassing once manufactured

Comfort

R-Values indicate that this system will reduce solar heat gain, particularly radiant gain, while also providing conductional resistance through the multi-layer polymer closed air cell structure. The thermal benefits achieved by these products result in a reduction in radiated heat transfer and in the demand for air conditioning and heating. This will potentially lead to improved individual thermal comfort levels, promoting a healthy indoor environment.

Indoor Environment Quality

Finished products do not emit VOCs, improving indoor air quality.

Electromagnetic Radiation

Safety

Products are a fibre-free, non-allergenic and non-irritant insulation system, eliminating health or occupational health and safety risks to the occupants or installers.

ECOLOGICAL QUALITY

Terrestrial

Emissions – The production of alumina from bauxite ores uses a chemical treatment, known as the Bayer Process (see Glossary). The alkaline mist associated with this process may have adverse land and vegetation impacts.

Polyester is principally derived from petroleum based polymers. Petroleum extraction and distribution can contribute to oil spills.

Physical – Mineral extraction of bauxite used to make aluminium will disrupt landscapes and alter ecosystems. Because bauxite deposits are found near the Earth's surface, mining requires removal of topsoil and overburden before deeper excavation occurs.

Petrochemical extraction can cause localised terrestrial disturbance around oil fields, via mining infrastructure, creation of access roads, and subsidence.

 

Aquatic

Emissions – The extraction and production of aluminium products have associated emissions to aquatic environments that have localised impacts around production facilities.

Petroleum extraction and distribution can contribute to oil spills.

Physical – Bauxite residues of red mud are often disposed of in tailing dams where the mud is allowed to settle. The excess water is discharged into marine environments.

Petrochemical extraction can cause localised aquatic disturbance around oil fields via mining infrastructure and dredging of the seabed.

 

Atmosphere

Greenhouse (GHG) – The process of manufacturing aluminium has very high energy requirements and subsequent GHG levels, particularly aluminium.

This product utilises polyester, which is fabricated from fossil fuels. Fossil fuels generate both atmospheric pollutants and greenhouse gases on combustion.

Operational efficiency – Products do not require energy during operation. Applying insulation reduces energy consumption of the building.

Re-use Efficiency – Subject to appropriate installation and removal techniques, these products represents a high value product with high re-use potential.

Toxics and Pollutants – Polyethylene is highly stable and does not readily react with other elements or compounds in the environment. Neither LDPE nor aluminum is sources of toxics or pollutants in use, but both create minor localized emissions around production facilities.

Ozone Depletion – There is no ODP in production, installation or on-going use.

Urban Heat Island Effects – PolyShield products are always covered by roof/wall cladding so its highly reflective surface is never exposed and hence creates no UHI benefits.

Noise – PolyShield Products will provide certain acoustic insulation, reducing noise levels.

 

Biodiversity

Bauxite mining leads to modified soil profiles, topography and drainage which impacts natural vegetation and biodiversity.  The oil extraction process results in the release of toxic drilling by-products into local rivers, while broken pipelines and leakage result in persistent oil spillage.

Product contains polyester which generates biodiversity impacts through the atmospheric emissions generated during the extracting and manufacturing processes. These have not been quantified in terms of impacts on biological systems, except in the case of oil-spill impacts which, while rare, can have significant long-term, localised impacts.

 

RESOURCE DEPLETION

Resource Efficiency

Aluminium is the third most abundant metal on Earth and the most abundant in the Earth's crust. The primary mineral source for aluminium is bauxite ore, a non-renewable resource with an estimated supply of 180 years based on current Reserve Life Index (RLI) (Source: Meyer, 2004, Availability of bauxite reserves, Journal of Natural Resources Research, p. 161).

PolyShield contains less mass of embodied resources for comparable R-values. Aluminium is relatively abundant and the amount used in PolyShield while very small, is also recyclable. Polyethylene is derived from fossil fuel based feedstock and is a non-renewable albeit recyclable.

Durability

Polyshield products can last up to 50 years.

Reusability

PolyShield products can be re-used if removed with care.

Repairability

Any tears can be repaired using heavy duty foil tape. However, the area of the product affected by the tear will not perform at its optimum due to reduction in air pockets, thereby reducing the effectiveness of the insulation. If significant damage occurs, the system should be replaced.

Design for Dematerialisation

PolyShield products have a low material content compared to bulk insulation.

Design for Disassembly

Product can not be disassembled. Product is installed using mechanical fixing; therefore the product can be easily removed.

Recyclability         

PolyShield products are installed using mechanical fixing and are therefore able to be disassembled. Mechanical fixing is preferable to glue-fixing, which limits disassembly and reuse.  The aluminium is bonded to the polyethylene and physical separation for purposes of recycling is limited. However, there is a growing number of recycling manufacturers accepting such material combination for recycling.

Maintenance

Not Required. Products are maintenance free.

No

Extended Producer Responsibility (EPR)

PolyShield products are packed with recycled clear polyethylene sheets. The sheets are 100% recyclable.
