Windows & doors questions, answered for Australian builds

A thermally broken — or "broken-bridge" — aluminium frame separates the inside and outside faces of the frame with a low-conductivity polyamide barrier. Aluminium conducts heat readily, so this barrier interrupts the path that would otherwise let heat flow straight through the metal. The result is a frame that stays closer to room temperature: warmer in winter, cooler in summer, with far less condensation on the internal face.

By breaking the thermal bridge through the frame, less heat is lost or gained at the window edge. Combined with double glazing, this lowers the overall U-value (the rate of heat transfer) and reduces the energy your heating and cooling has to spend maintaining a comfortable interior. For Australian builds, it helps meet the energy provisions of the National Construction Code without oversizing mechanical systems.

U-value measures how much heat passes through the whole window — a lower number means better insulation. SHGC (Solar Heat Gain Coefficient) measures how much of the sun's heat passes through the glass — a lower number means less unwanted heat in summer. The right balance depends on climate and orientation: cooler southern climates often favour heat retention, while hot northern climates favour blocking solar gain.

Yes. Thermal performance values for our thermally broken and double-glazed series are available to support energy efficiency reporting under the National Construction Code. Provide your series selection and glazing makeup and we will issue the performance data your energy assessor needs.

Yes. The sealed air or gas gap between two panes dampens sound transmission as well as heat, which is valuable on busy roads, near flight paths or in dense developments. Acoustic performance can be tuned further with laminated glass or wider cavities — tell us your situation and we will recommend a build-up.

Yes. Coastal sites expose hardware and frames to airborne salt, which accelerates corrosion on poorly finished aluminium. Our frames use marine-appropriate surface treatments and corrosion-resistant hardware so they hold up in salt-laden environments. For beachfront and harbour-front projects, let us know the proximity to the coast so we can specify the right finish grade.

Aluminium is finished with powder coating or anodising over a cleaned and pre-treated surface. These finishes form a durable protective layer that resists salt, UV and weathering far better than bare or lightly coated metal. Powder-coat colour ranges are wide, and the finish is selected to suit the exposure category of your site.

Aluminium does not rot, warp, swell or require repainting the way timber can, and it carries structural loads at slimmer sightlines than uPVC. With a quality finish it remains dimensionally stable across large temperature swings, which is why it is the dominant framing material for Australian commercial and high-performance residential glazing.

Maintenance is minimal: periodic washing of the frames and glass, clearing of drainage weep holes, and occasional lubrication of moving hardware. In coastal zones we recommend more frequent fresh-water rinsing to remove salt deposits. No repainting or sealing is required for the frame finish under normal conditions.

Yes. Products are custom-fabricated to your drawings and window schedule in millimetre dimensions, configured for Australian openings, reveals and installation methods. Send your plans or schedule and we will manufacture to match rather than forcing you to design around fixed sizes.

Send us your window and door schedule, floor plans or a list of openings with sizes and configurations. Our technical team prepares a quote with the recommended series, glazing and finishes, along with the compliance documentation that applies. Once the specification is confirmed, the order moves to fabrication.

Lead time depends on the size and complexity of the order, and is confirmed at quotation. Products are manufactured, quality-checked and packed for sea freight to Australian ports. We can advise on container loading and coordinate with your nominated freight forwarder or customs broker for delivery to site or warehouse.

Pricing is based on the total package for your project rather than a fixed unit minimum, which makes us well suited to multi-unit and commercial builds. Contact our team with your schedule and we will confirm pricing and any order requirements for your build.

Orders are supplied with the relevant AS 2047:2014 test reports, AS/NZS 1170.2 wind ratings, AS 1288 glazing statements and — where applicable — thermal performance data for NCC reporting. We compile these into a single documentation pack so your certifier has everything in one place.
