Aluminum Windows vs uPVC: Which Is Better in Malaysia?

Introduction

When choosing windows for homes or commercial buildings in Malaysia, aluminum windows and uPVC windows are the two most popular options.
Due to Malaysia’s hot, humid, and tropical climate, selecting the right window material is critical for durability, ventilation, and long-term performance.

So, which is better for Malaysia — aluminum windows or uPVC windows?
This guide compares them in terms of climate suitability, cost, durability, and applications to help you make the right decision.

Aluminum Windows vs uPVC: Material Comparison

Aluminum Windows

• Made from high-strength aluminum profiles

• Lightweight but extremely durable

• Suitable for large openings and slim frames

• Excellent corrosion resistance when properly treated

uPVC Windows

• Made from unplasticized polyvinyl chloride

• Good insulation performance

• Bulkier frames compared to aluminum

• Limited color and size options

👉 Key difference: Aluminum offers strength and flexibility, while uPVC focuses on insulation.

Performance in Malaysia’s Hot & Humid Climate

Malaysia’s climate presents three main challenges:

• High humidity

• Strong sunlight

• Heavy rainfall

Aluminum Windows in Malaysia

• Powder-coated aluminum resists corrosion and moisture

• Does not warp or swell in humid conditions

• Better ventilation options (sliding, casement, louver systems)

• Ideal for tropical climate applications

uPVC Windows in Malaysia

• Not affected by moisture

• However, prolonged exposure to UV may cause:

  • Color fading

  • Material aging

• Less suitable for very large window sizes in hot climates

✅ Verdict: Aluminum windows perform more reliably in Malaysia’s tropical environment.

Thermal & Energy Efficiency

uPVC Windows

• Naturally good thermal insulation

• Suitable for air-conditioned rooms

• Lower heat transfer

Aluminum Windows

• Modern aluminum windows use:

  • Thermal break systems

  • Double or Low-E glass

• Provide excellent insulation while maintaining strength

👉 For Malaysia, thermal-break aluminum windows offer the best balance between insulation and durability.

Durability & Maintenance

Aluminum windows last longer, especially for high-rise and coastal projects in Malaysia.

Design & Application Flexibility

Aluminum Windows

• Slim frames = larger glass area

• Suitable for:

  • High-rise apartments

  • Commercial buildings

  • Modern villas

  • Sliding & folding systems

uPVC Windows

• Best for:

  • Small to medium residential homes

  • Limited opening sizes

• Design options are more restricted

👉 For modern Malaysian architecture, aluminum windows are more versatile.

Cost Comparison in Malaysia

• uPVC windows

  • Lower initial cost

  • Suitable for budget projects

• Aluminum windows

  • Slightly higher upfront cost

  • Lower long-term maintenance

  • Better return on investment for developers

💡 For large projects, aluminum windows are often more cost-effective over time.

Which One Should You Choose in Malaysia?

Choose Aluminum Windows if:

• Your project is in a hot & humid area

• You need large openings or slim profiles

• You want long-term durability

• You are working on villas, condominiums, or commercial buildings

Choose uPVC Windows if:

• Budget is the main concern

• Project is small-scale residential

• Window sizes are limited

👉 Overall Recommendation:
For most projects in Malaysia, aluminum windows are the better long-term solution.
