Aluminium glass windows have become increasingly popular thanks to their elegance, durability, and excellent insulation performance. However, to ensure smooth operation and preserve their aesthetics, regular aluminium window maintenance is essential. In this article, we will explore in detail the proper ways to care for aluminium windows and the key points to extend their service life.

Why Should You Maintain Aluminium Glass Windows?

Many homeowners assume that aluminium glass windows are highly durable, resistant to warping or rust, and therefore require little maintenance. In reality:

• Aluminium frames can tarnish or oxidize if exposed to moisture for a long time.
• Rubber gaskets (EPDM seals) may deteriorate, losing airtightness and causing water leakage during rain.
• Sliding tracks and rollers can accumulate dirt and become stiff if not cleaned and lubricated.
• Glass surfaces may become scratched, stained, or foggy, reducing their original clarity and shine.

Therefore, regular care and maintenance are the most effective ways to prevent damage, save on costly repairs, and maintain the aesthetics of your building.

Regular Maintenance Tasks (Monthly / Quarterly)

1. Clean Aluminium Frames and Glass Surfaces

• Use a soft cloth or microfiber towel with a neutral pH cleaning solution.
• Wipe gently to avoid fading aluminium coating or leaving streaks on glass.
• Clean from top to bottom in vertical or horizontal strokes to minimize water stains.

2. Clean Tracks and Rollers

• Use a handheld vacuum cleaner or soft brush to remove dust and debris.
• Apply a few drops of silicone spray or light lubricant to keep rollers moving smoothly.
• Avoid using heavy oil or grease as they trap dust and cause track jamming.

3. Inspect Screws, Hinges, and Locks

• Ensure all screws are tight and secure.
• Apply lubricant to hinges and locking mechanisms for smooth operation.

4. Check Sealant and Gaskets

• If rubber gaskets show cracks or shrinkage, replace them to maintain airtightness.
• Inspect silicone sealant or structural glazing sealant around glass edges—reapply if peeling or damaged to prevent water ingress.

Periodic Maintenance (Every 6–12 Months)

• Remove glass panels or sashes (if the design allows) to clean hidden corners thoroughly.
• Inspect for oxidation or corrosion: sand lightly with fine-grit sandpaper and touch up with aluminium protective coating if needed.
• Check drainage channels and weep holes to ensure water flow is not blocked.
• For Low-E glass or specialty coated glass, strictly follow manufacturer guidelines—avoid harsh chemicals or scraping the surface.

What NOT to Do When Maintaining Aluminium Windows

❌ Do not use cleaners containing acid, alkali, or abrasive particles.
❌ Do not wash when the window is hot from direct sunlight.
❌ Do not scrape glass surfaces with knives or sharp metal tools.
❌ Do not spray high-pressure water jets directly into window joints or seals.

Special Care in Different Environments

• Coastal homes: Salt in the air accelerates corrosion → wash with fresh water more frequently.
• Dusty or polluted urban areas: Increase cleaning frequency, especially for sliding tracks and gaskets.
• High-rise buildings: Regularly check drainage holes and channels to prevent blockages from rainwater and debris.

Conclusion & Quick Tips

Proper aluminium window maintenance not only extends lifespan and preserves aesthetics but also ensures safe and smooth operation. Establish a habit of:

• Monthly cleaning to keep surfaces spotless.
• Biannual inspection for hardware and accessories.
• Annual comprehensive maintenance for overall durability.

For added convenience, consider booking a professional maintenance service, where experts with the right tools and experience can help you save time while ensuring maximum efficiency.
