Aluminium Window Performance and Maintenance Guide

As a global AS 2047 aluminium windows supplier, Hanstim focuses on delivering high-performance aluminium window systems designed for modern construction, climate challenges, and long-term durability. For B2B buyers—including builders, developers, contractors, and distributors—understanding how aluminium windows perform and how to maintain them is essential to achieving stable building performance and reduced lifecycle costs.

This guide provides a comprehensive overview of aluminium window performance, structural design, waterproofing principles, acoustic performance, Timber Reveal installation methods, and long-term maintenance practices, helping project teams ensure window systems operate efficiently throughout their service life.

1. Aluminium Window Performance Overview

Aluminium window performance is determined by several core components: structural strength, sealing systems, glass configuration, hardware, thermal performance, and compatibility with local standards. At Hanstim, all window systems are engineered based on AS/NZS 2047 – Windows and External Glazed Doors, meeting the structural and performance requirements of the Australian market.

Key performance dimensions include:

• Structural stability under wind pressure
• Airtightness and water penetration resistance
• Acoustic performance
• Durability against corrosion and UV exposure
• Material compatibility with common installation systems such as Timber Reveal

These core attributes ensure that Hanstim windows deliver reliable performance across residential, commercial, and mid-rise building applications.

2. High-Strength Aluminium Profiles (6063-T5)

The durability and stability of a window begin with the aluminium profile. Hanstim uses high-strength 6063-T5 aluminium, offering enhanced rigidity, corrosion resistance, and long-term stability.

Profile Thickness Range

• 1.4 mm – Suitable for residential and mid-rise buildings
• 2.0 mm – Preferred for high-rise, high-wind-load, and coastal applications

This thickness range ensures compliance with AS 2047 structural requirements while delivering superior strength under wind load and building movement.

Surface Finishes

• Powder Coated (recommended for external environments)
• Anodized (ideal for high-corrosion or coastal regions)

Color Options

Popular choices include charcoal, black, silver, and other neutral shades that match the modern architectural aesthetic in Australia, Europe, and coastal markets.

3. Acoustic Performance (Acoustic Design)

With growing concerns about residential noise levels, acoustic performance plays a vital role in modern window design. Hanstim integrates multiple sound-reducing strategies to enhance comfort and noise isolation:

• EPDM gaskets to achieve strong sealing and long-term elasticity
• Multi-chamber aluminium profiles to reduce resonance
• Optional laminated glass (6.38–10.38 mm) for enhanced sound insulation
• Upgradable double glazing to further improve acoustic performance

EPDM is widely recognized as the most durable sealing material due to its weather resistance, UV stability, and excellent sound-dampening properties, making it the preferred choice for long-service-life window systems.

4. Waterproofing Performance (Water Penetration Resistance)

Rainfall, wind-driven water pressure, and external moisture are major risks for aluminium windows installed in external building envelopes. Hanstim adopts a multi-layer waterproofing system to ensure long-term reliability.

Key Waterproofing Features:

1. Multi-Chamber Drainage System

Designed to guide rainfall away efficiently, preventing water accumulation within the frame.

2. Dual-Layer Sealing

A combination of internal EPDM gaskets and external silicone sealant creates a robust waterproof barrier.

3. Enhanced Sill Height

Improved frame sill design reduces the risk of water intrusion during heavy storms.

4. Flashing Compatibility

Our window frames are designed to work seamlessly with Stainless Steel Flashing, an essential component in Australian building practices.

This waterproofing structure ensures compliance with AS 2047 water penetration standards and long-term stability in regions with heavy rainfall or coastal climates.

5. Timber Reveal System Compatibility (Common in Australia)

The Timber Reveal System is the most widely used installation method in Australian residential construction. In this system, aluminium windows are fitted into a wooden reveal that is then installed into the building structure. This installation method offers higher accuracy and better thermal buffering.

Hanstim window systems are fully compatible with Timber Reveal installation and are designed to meet its structural and waterproofing requirements.

Function and Advantages

• Provides a stable mounting frame
• Improves thermal performance between wall and window
• Allows better installation alignment and reduces tolerance issues

Waterproofing Design with Timber Reveal:

• Between aluminium frame and timber reveal → Apply neutral silicone sealant
• At the top of the reveal → Install Stainless Steel Flashing to block water entry
• Between reveal and flashing → Apply additional sealant to create a continuous waterproof layer

This installation method significantly enhances the window’s long-term waterproof performance and is strongly recommended for Australian building projects.

6. Sealant Requirements Based on AGWA Guidelines

The Australian Glass and Window Association (AGWA) specifies strict installation and sealing requirements. According to AGWA:

“Sealants shall be compatible with adjacent materials and applied to clean, dry surfaces.”

Compliance Recommendations:

• Use neutral cure silicone compatible with aluminium, timber, and stainless steel
• Avoid acidic sealants that can corrode aluminium
• Ensure all surfaces are clean, dry, and free of dust or oil
• Maintain continuity of the external waterproof layer
• Inspect sealant annually to ensure long-term performance

Following AGWA guidelines ensures that your installation meets Australian industry standards and reduces the likelihood of future leakage issues.

7. Long-Term Maintenance Guide (Maintenance Practices)

Even high-quality aluminium windows require periodic maintenance to maintain performance over their lifetime. Below are recommended practices to help extend service life and maintain AS 2047 compliance.

(1) Aluminium Frame Cleaning

• Use mild, non-abrasive detergents
• Avoid corrosive or acidic cleaners

(2) Sealant Inspection

• Inspect every 12–24 months
• Replace if cracking, peeling, or detachment is observed

(3) Drainage System Cleaning

• Ensure drainage holes are unobstructed
• Prevent water accumulation during storms

(4) EPDM Gasket Maintenance

• Replace if hardened or losing elasticity
• Avoid solvent-based cleaners

(5) Hardware Lubrication

• Lubricate hinges, rollers, and locks every 6 months
• Ensure smooth operation and reduced wear

Regular maintenance reduces operational issues and extends system durability, providing better performance for end-users.
