Preparation

Magnetite® attaches discreetly to the inside of window reveal. A Magnetite subframe is installed within the existing window reveal using screws and or double sided adhesives. This framework provides a flat surface for the magnetized glazing panels to snap into, providing an air tight magnetic seal. In situations where a reveal/casement is not present then a casement would be installed around the window for the system to fit into.

ECOSPECIFIER LIFE-CYCLE ASSESSMENT

INTEGRATED DESIGN AND POLICY ISSUES

Windows are one of the most exposed elements of buildings to sun and weather. As such energy efficiency, established by referring to a Window Energy Rating Scheme (WERS), is an important environmental priority. Magnetite® can achieves up to 6 cooling stars and up to 6 heating stars compared to a generic window with a standard aluminium frame. This equates to between 35 and 76% cooling improvement and between 33 and 62 heating improvement over the base window comparison depending on existing window frame (Click here for full table).

High performance windows with airtight seals, such as Magnetite, can achieve significant indoor environmental quality and energy efficiency benefits, especially when fitted with eco-preferred blinds or screens and automation hardware. Window frame, glazing, sealing, ventilation and shading are significant contributors to overall building thermal and human comfort.

HUMAN HEALTH

Health

PVC is a contentious material; however Magnetite frames are made from unplasticised PVC (uPVC) which has no problems associated with plasticisers. Please see Glossary for more information on PVC.

Product is free of lead and tin stabilizer using organic based stabilizer.  These windows also have the benefits of reduced condensation, mould, and mildew in cold or air conditioned sub/tropical climates.

Comfort

Insulating the windows provides a more stable indoor temperature. The magnetic seal eliminates drafts from operational windows and convection off large glass panels. The product is designed to insulate the entire existing window system (frame and glass). Using clear glazing on North facing windows would increase passive solar heating as the clear glazing allows radiant heat to enter the premise and the optical grade acrylic glazing helps to trap the heat in the winter months. Using the solar films that are available with the double glazing system on the east and west facing windows will minimise passive unwanted heating by creating a barrier against radiant heat through the glass and from the frame.

Indoor Environment Quality

No VOC testing has been done on the product.

Electromagnetic Radiation

Manufacturer states that the magnets used in their product are not strong enough to affect machinery such as computers they are similar in style to the magnets used to keep refrigerator doors shut.

Safety

Product is primarily plastic and can be cut with sheers rather than saws. The glazing panel is an optical grade acrylic and is 18 times stronger than glass. If the Magnetite panel were to break it would not shatter.

uPVC is highly toxic in small quantities if burnt and is known to generate hydrogen chloride, carbon monoxide and other toxic gases.

ECOLOGICAL QUALITY

Terrestrial

Emissions - Chlorine is a key constituent of PVC and the emissions from its production consist of chlorine and hydrogen. Mercury is also produced during chlorine production.

Physical - Provided that state-of-the-art technology is used the production of PVC, terrestrial, aquatic and atmosphere pollution impacts are considered to be low. Additionally, this product does not constitute a substantial impact on the toxicity of landfill leachate and gas (Life Cycle Assessment of PVC and of principal competing materials, Final Report, commissioned by the European Union, July 2004)

Aquatic

Emissions - Ethylene is produced in the initial production stage of PVC and the emissions to water consist of methanol and butane.

Physical - The petrochemical portion of PVC results in potential sea pollution in the extraction of oil. Other aquatic emissions include methanol and butane in the production of ethylene as well as mercury and chlorine in the production of chlorine (Life Cycle Assessment of PVC and of principal competing materials, Final Report, commissioned by the European Union, July 2004).

Atmosphere

Greenhouse (GHG) - This product utilises PVC, which is fabricated from fossil fuels. Fossil fuels generate both atmospheric pollutants and greenhouse gasses on combustion. However through reducing the need for air conditioning and heating, the greenhouse gases produced in the building can be significantly reduced by double glazing.

Greenhouse intensity - 9.71 kgCO2e / m2

Transport intensity - Product is manufactured in Sydney and transported by truck. The panels are manufactured in Indonesia and transported to Australia by ship.

  • Greenhouse Intensity for Container Shipping of panels - 0.09 kgCO2e / m²

*Calculation is based on data sourced form Bath University, UK and Alcorn, New Zealand.

Transport intensity figures sourced from Australian National Greenhouse Gas Inventory 1990, 1995 and 1999 and WWF International, Inland Navigations and Emissions, 2005.

Operational efficiency - Product reduces the energy consumption of a building by creating a more constant internal temperature which reduces heating and cooling requirements.

Re-use Efficiency - Product is not reusable however, it enables existing windows to be reused which reduces waste.

Toxics and Pollutants - uPVC is highly toxic if burnt, see safety.

Ozone Depletion - No CFC's or HFC's are used as blowing agents in the manufacture of this product

Urban Heat Island Effects - Product may reduce levels of waste heat from air conditioners as double glazing may reduce use of cooling systems

Noise - The product will limit noise coming into or out of the building

Biodiversity

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

RESOURCE DEPLETION

Resource Efficiency

Thin steel strapping attached to the frame to provide a magnetic surface for the panel to snap to. This steel is sourced from post-consumer waste from the siding industry.

Embodied Fossil Fuel Energy

Embodied Energy: 200.27 MJ/m² of total product*

*Calculation is based on data sourced form Bath University, UK and Alcorn, New Zealand.

Transport intensity - Product is manufactured in Sydney and transported by truck. The panels are manufactured in Indonesia and transported to Australia by ship.

Energy Intensity for Container Shipping of panels - 1.15 MJ / m2

Embodied Water

Not known

Durability

15-20 years expected life

Reusability

Product is unlikely to be re-used due to the variation in size of window panels.

Repairability

Product can generally be repaired; any major gauges may result in the requirement of a new panel

Design for Dematerialisation

Product is designed to be retrofitted thus significantly reducing waste and unnecessary damage to building fabric and created by window removal and replacement.

Design for Disassembly

Product can easily be removed from window casing

Recyclability

All plastic offcuts are recycled. PVC is stored and sent back to the manufacturer in Sydney prior to each manufacturing run. Acrylic panels are also recycled and magnets are re-used in new frames.

Maintenance

Product can be cleaned when dirty with soap and water solution and a soft cloth.

Product Take back Scheme

Yes, manufacturer will take back product when no longer needed for recycling at the clients request.
