AS 2047 Aluminium Windows and Australian Standards Guide

1. Introduction: Why AS 2047 Matters for B2B Buyers

For builders, contractors, developers, and importers targeting projects in Australia, compliance with AS 2047 – Windows and External Glazed Doors in Buildings is nonnegotiable. AS 2047 sets the performance criteria for structural strength, water and air tightness, durability, and operating performance for aluminium windows used in building envelopes.

These standards are referenced directly in the National Construction Code (NCC) — Australia’s mandatory building regulation covering safety, health, amenity, and sustainability requirements in construction.

Choosing a certified AS 2047 aluminium windows supplier ensures not only compliance but reduced risk for project approvals, fewer site defects, and improved longterm performance in diverse Australian climates.

2. What AS 2047 Covers

AS 2047 – Windows and External Glazed Doors in Buildings (2014) specifies:

• Structural performance: Resistance to windpressure induced deflection and ultimate strength.
• Operating performance: Smooth and reliable opening/closing force requirements.
• Air infiltration: Limits on air leakage to maintain internal conditions.
• Water penetration: Resistance against rain and moisture intrusion.
• Durability: Frame and hardware performance over time in real conditions.

Every external window or glazed door installed in vertical building façades in Australia must comply with AS 2047 performance provisions unless exempted (e.g., fixed external louvres or nonvertical applications).

3. How AS 2047 Works with Other Standards

AS 1288 – Glass in Buildings

While AS 2047 focuses on the full window system, AS 1288 governs selection, sizing, and locationbased safety requirements of the glass itself — including thickness, edge support, and safety glass criteria.

In NCC compliance, meeting AS 1288 is essential where glass performance and safety (e.g., for doors, wet areas, or impact risk locations) is critical.

NCC (National Construction Code)

The NCC sets minimum regulatory mandates. “Deemedtosatisfy” compliance for windows is typically achieved by demonstrating AS 2047 (plus applicable glass standards like AS 1288 and other code requirements such as AS 4055 for wind classifications).

4. What B2B Buyers Look for in an AS 2047 Aluminium Window Supplier

From a procurement and project delivery standpoint, the key criteria include:

• Verified AS 2047 compliance: Tested traceability reports showing performance under AS 4420 series tests (deflection, air, water, operating forces).
• Documentation & certificates: Clear performance labels and certificates for certification audits.
• Technical support: Engineering drawings, specification sheets, and installation guide support for site teams.
• Glass systems aligned to AS 1288: Including laminated, LowE or insulation options based on building class and local conditions.

5. Hanstim’s Compliance and Technical Strengths

As a global AS 2047 aluminium windows supplier, Hanstim integrates standardsbased engineering into every phase from profile design to installation accessories.

Key product strengths include:

✔ Highstrength profile design: 1.6–2.0 mm thick aluminium alloy ensures structural strength and reduced deflection even under high wind loads (especially in coastal or elevated applications).
✔ Robust waterproofing system: Duallayer drainage channels and weep holes engineered to meet water penetration resistance criteria.
✔ Premium sealing materials: Neutral cure silicone and durable EPDM gaskets for longterm airtightness and weather resistance.
✔ Glass flexibility: Options including 5+5 mm insulated units, LowE coatings, and laminated safety glass to satisfy both AS 2047 and AS 1288 needs.
✔ Installation compatibility: Designed for Timber Reveal and stainlesssteel flashing systems commonly used in Australian builds to achieve AGWArecommended waterproof detailing.

Together, these features support compliance with AS 2047 performance test criteria and minimize risks of air and water leakage on site.

6. Installation & Compliance Best Practices (Beyond Product Supply)

Selecting the right product is only half the solution — correct installation and documentation are equally important:

Preinstallation planning

• Verify design wind pressure and exposure category aligned to AS 4055 wind maps.
• Match glass selection to AS 1288 safety and thickness guidelines.

Installation controls

• Ensure correct rock and packer usage to keep frame true and square.
• Align builtin drainage with cladding drainage paths without blocking weep holes.
• Use neutral cure sealants and avoid acidic products that can corrode aluminium frames.

By providing a full installation compliance guide, suppliers like Hanstim help reduce onsite risk and warranty issues — a competitive differentiator often missing from competitor offerings.

7. Product Selection: Matching Windows to Project Needs

Architects and specifiers should consider the following:

• Highperformance glazing: Use LowE and doubleglazed units in areas where thermal performance is critical.
• Acoustic considerations: Laminated panes combined with EPDM sealing deliver enhanced sound reduction.
• Coastal & corrosive environments: Anodized or marinegrade powder coating protects profiles.
• Large openings: Coordinate wind load and deflection requirements with NCC and AS 2047 framing specifications.

Hanstim offers product variants and customization options that adapt to these technical needs — an advantage for global B2B clients seeking scalable solutions.

8. LongTerm Maintenance and Lifecycle Value

Aluminium window systems compliant with AS 2047 not only perform well initially but can offer lower lifecycle cost when:

• Frames and gaskets are inspected annually to prevent seal failures.
• Drainage channels remain clear from debris.
• Hardware is lubricated for smooth longterm operation.
• Glass and frames are periodically checked for impact or environmental wear.

By supplying modular frames and easyreplace components, Hanstim extends service life while facilitating future maintenance.
