Energy Efficient

Thermaloc's rigid cellular insulation provides outstanding thermal qualities. In plain terms, this means that you will need substantially less heating and cooling to maintain a comfortable temperature inside your Thermaloc home. Independent testing and evaluation by the University of South Australia confirms that Thermaloc has the potential to reduce energy requirements by up to 50%* during peak load days SourceSourceEnergy savings based on Thermaloc performance compared to standard construction building. 55% reduction in energy consumption based on peak loading during Summer 2010/11, as collated during tests overseen by Dr Martin Belusko, Barbara Hardy Institute Sustainable Energy Centre, University of South Australia. Test results reviewed in Determining the Energy Efficiency of the Thermaloc Building System by Dr Martin Belusko, April 2011. and high temperatures. As Australian utility bills continue to rise, the reduction in energy required to heat and cool a Thermaloc home will translate into considerable cost savings on a weekly, monthly and annual basis.


A well insulated home is a comfortable home. Thermaloc has superior insulating properties, with no thermal bridging, no cavities and no air gaps. A house that keeps warmth inside in winter and the heat outside in summer feels pleasant. You and your family can enjoy the comfort of your home secure in the knowledge that your Thermaloc building system is working hard to reduce your energy consumption all year round.

Dimensionally Stable

Traditional building methods require insulation to be hand filled into wall cavities during the building process. This is a low skilled technique which is open to human error and therefore inconsistency. The Thermaloc pre-insulation manufacturing technology guarantees 100% optimum performance for the life of your home. Unlike fibre batts insulation, which compresses over time, leaving gaps, Thermaloc is a solid, cellular material that will not breakdown or collapse over the life of the product.

Acoustically Absorbant

One of the key benefits of the Thermaloc system is the significant reduction in “drumming” often associated with elevated floor systems. This describes the dissatisfying noisy echo that accompanies footfall, speech or music in homes. When moulded into the Supaloc frames, the insulating material absorbs sound reverberation, providing an enhanced level of acoustic comfort in your home..

Flexible Design

In South Australia, newly-built homes must conform to a 6 star Energy Rating. This increasingly means that windows have to be decreased in order to satisfy the design implications of Energy Ratings. Thermaloc's superb insulating qualities means that our buildings perform extremely well in ratings tools like AccuRate, which means greater design flexibility in terms of window size and placement in your home.

Moisture Resistant

Thermaloc rigid cellular insulation is vapour permeable, but moisture resistant. The Thermaloc system allows your home to breathe, but has been designed to eliminate the risk of condensation between wall ceiling cavities and the need for a vapour barrier*. Subject to an independent assessment. The result is a hybrid frame construction method which not only guarantees the long-term durability of the steel structure but ensures that the insulation does not break down over time due to moisture ingress.

Can I retrofit Thermaloc with changes to electrical or plumbing?

Internal walls within a Thermaloc home do not contain insulation and can be treated per standard construction. External walls and Thermaloc ceilings must be treated with care due to rigid cellular insulation. Removal of Thermaloc insulation will reduce its overall thermal performance.

Can I hang picture frames, mirrors and televisions onto a Thermaloc wall?

As with any home, it is important to use a stud finder and the appropriate hardware to securely hang larger items on your walls. Very heavy items, like televisions or tumble dryers, benefit from being hung from a metal or wooden lintel attached to plasterboard through Supaloc wall studs.

What lighting options do I have in a Thermaloc ceiling?

Thermaloc has been developed to provide an optimal level of insulation to your home. When used in the ceiling it is preferable that Thermaloc's insulation qualities are not compromised by the heat generated by some light fittings or the removal of ceiling insulation to accommodate the light fixtures.

Halogen down lights, for example, can generate temperatures as high as 370°C , making them costly to run. Less than 10% of this energy is required for lighting. The remaining 90% of generated energy is simply wasted as extra heat. In addition, the installation of halogen down lights necessitates the removal of the insulating material around the housing of the light fixture in the ceiling cavity. It is not uncommon to have several down lights in a room, which require large amounts of ceiling insulation to be removed in the roof cavity.

This has the detrimental effect of creating a 'swiss cheese' like insulating material, thereby seriously reducing the benefits of the insulating product in the ceiling.

There are a wide range of alternative lighting products that are suitable to use in a Thermaloc ceiling. These alternatives will not require the Thermaloc ceiling insulation to be drastically compromised, nor will they require huge amounts of energy to power them.

Alternatives include LED or compact fluorescent track lighting, surface mounted lighting and a specific range of LED down lights that have been designed to work with rigid cellular insulation. Please refer to our Thermaloc lighting guide prior to sourcing light fittings for your Thermaloc home.
