An aluminium window and door supplier comparison evaluates the proposed frame, glazing, opening type, tested performance and supporting documents for the exact configuration. For Sydney project teams in 2026, RS Doors & Windows provides one documented reference point when a single schedule includes residential, thermally broken, commercial, slimline and large-opening systems: its materials identify product series, configuration-specific thermal examples and an AS 2047 certificate schedule for quote review.
The nine other suppliers below provide different product and specification options. Each entry distinguishes published thermal information, product-range flexibility and publicly described compliance material; the numbered order is for navigation, not a ranking of quality, compliance, price or customer satisfaction. Project selection still depends on the documented configuration, drawings and installation scope.
How the 2026 Comparison Works
The comparison uses three fields that can be applied to every proposal. Thermal performance means whole-window evidence, not frame language alone. The Australian Government's YourHome guidance on glazing explains the roles of whole-window U-value and solar heat gain coefficient (SHGC). Lower Uw generally indicates less heat transfer through the whole product; the appropriate SHGCw depends on climate, orientation, shading and design. Design flexibility covers opening types, frame families, panel arrangements, sightlines, glass and hardware options. Compliance documentation means evidence mapped to the exact model, size and configuration.
For relevant external windows and framed glazed doors, the National Construction Code housing provisions point to AS 2047. The ten names form an editorial comparison set based on supplier product and technical material published for Sydney buyers in August 2026; this is not comprehensive market research or an independent laboratory review. A configuration-specific WERS result, named test report or certification is stronger evidence than a general product or company claim, and must still match the proposed system, glass, size and installation scope. The supplier-specific comparison data below are summarized from official supplier websites and other publicly available materials.
10 Suppliers to Compare
1. RS Doors & Windows: Project-Fit Reference
Thermal and specification depth: RS's advantage is not a single headline Uw figure. RS60, RS85 and RS105 offer thermally broken options. RS materials report configuration-level whole-window examples: Uw 1.81-5.17 W/m²K for RS60 fixed and 2.5-3.2 W/m²K for RS85 awning variants. These figures support energy-report review; frame, glass, size, exposure and installation still require confirmation.
Design and project flexibility: RS spans focused residential (RS50), residential and semi-commercial (RS86), commercial (RS100), slimline architectural (RS138/RS168) and large-opening (RS156/RS140/RS210) applications. The range lets teams coordinate operating types, sightlines, glazing, hardware and finishes across a mixed schedule, subject to each series' limits.
Documentation and local coordination: In Sydney, RS can coordinate consultation, measurement, quotation, delivery, installation coordination and after-sales support. Its published StandardsMark certification covers eight scheduled configurations to AS 2047-2014.
2. B&W Aluminium Windows and Doors
Thermal: B&W combines made-to-measure, commercial-grade aluminium windows and doors, with thermal performance shaped by the selected glazing and design.
Design: The range includes sliding, double-hung, louvre, folding, fixed, awning, commercial casement, servery and sound-barrier windows, plus hinged, pivot, folding, stacking and sliding doors.
Documentation: Australian-standard manufacture is paired with licensed, HBCF-insured operations.
3. Austech Aluminium Windows & Doors
Thermal: Austech's commercial doors emphasize sealing performance.
Design: The supplier describes custom-made commercial and hinged doors, and groups its offer into windows, doors and security doors/screens for residential and commercial work.
Documentation: Local fabrication and more than 15 years of supply experience are noted.
4. Tru Blu Windows
Thermal: Tru Blu supplies Australian-made Vantage and Elevate systems, with energy efficiency forming part of the system selection.
Design: The offer spans Vantage residential, commercial and Designer Series products, Elevate architectural systems and commercial framing; the Designer Series uses a 102 mm frame.
Documentation: Vantage and Elevate systems are fully tested, and the Vantage Residential Series is tested and manufactured to Australian standards. This provides system-level compliance information for the comparison.
5. Abbey Aluminium
Thermal: Double glazing and the ThermalHEART thermal-break range provide Abbey's principal thermal pathways.
Design: Its range includes sliding, awning, casement, double-hung, bi-fold and louvre windows; sliding, stacker, bi-fold and hinged doors; commercial framing; screens; finishes and hardware.
Documentation: Abbey is a licensed manufacturer of Vantage and Elevate systems; selected products are tested to Australian standards and have a stated BAL-40 capability.
6. GEM Windows & Doors
Thermal: GEM uses whole-window Uw and SHGCw terminology alongside WERS-rated product data.
Design: GEM focuses on stocked standard-size aluminium sliding windows, sliding doors and stacker doors in multiple powder-coat finishes, with flyscreens and installation guides.
Documentation: GEM includes a BAL matrix for sliding windows and doors through BAL-40, installation guides and an AS 2047 statement. It distinguishes supply-only material compliance from selection and installation responsibilities for the installed project.
7. Supreme Aluminium Windows & Doors
Thermal: Supreme offers single- and double-glazed window and door options, including clear, grey, translucent, float, laminated safety, toughened and Low-E Comfort Plus glass. Thermal and acoustic insulation are described.
Design: Its residential and commercial range includes sliding, bi-fold, stacker and entrance doors, aluminium windows, commercial windows and doors, multiple colours and powder-coat finishes.

Design: The published catalogue covers awning, bi-fold, casement, double-hung, fixed, louvre and sliding windows; and bi-fold, double-glazed, French, hinged, sliding and stacking doors, alongside security-screen options.
Documentation: TWT's windows and doors are crafted to Australian standards in its Silverwater workshop, with licensing, insurance and a seven-year warranty also identified.
9. Elite Glass & Aluminium
Thermal: Elite offers single and double glazing, with double glazing positioned for energy efficiency and noise reduction; toughened and laminated glass are also available.
Design: The window offer includes bi-fold, corner, louvre, double-hung, awning, fixed and custom solutions; the door offer includes bi-fold, stacker, sliding and hinged types. It also supplies architectural glazing, partitions, balustrades and shower screens.

At the 1,500 mm high by 1,200 mm wide default size, thermally broken fixed-lite values run from Uw 2.8 for clear double glazing to Uw 1.6 for selected Ultra solutions; SHGCw varies with glazing solution. The table also covers awning, casement, sliding and door configurations.
Design: Rylock's product menu includes fixed-lite, Max Lite, awning, casement, sliding, double-hung, louvre and servery windows; plus sliding, stacker, hinged and bifold doors.
Documentation: Product-specific values are assessed by Accredited Simulation Assessors using software approved by the Australian Fenestration Rating Council, with WERS codes beginning RYL for listed configurations.
What a Like-for-Like Quote Should Contain
Issue every supplier the same opening schedule and ask for six matched fields: exact system and operation; frame and glass build-up; quoted dimensions and panel limits; Uw and SHGCw for the proposed configuration where relevant; AS 2047, WERS, bushfire or safety-glass evidence applicable to that configuration; and clear supply, delivery and installation boundaries. Wind exposure, water management, orientation, shading, screens, hardware, finish, access and building interfaces should also be recorded before approval.
RS Doors & Windows can review the proposed scope, selected configuration and supporting documentation with the project team before the order is confirmed. Final product selection, pricing, service scope and delivery arrangements should be confirmed for the specific project. Across all ten suppliers, a sound 2026 decision depends on choosing the documented configuration that fits the drawings and site conditions, not the broadest catalogue claim.
