For distributors in the Middle East, Africa, Southeast Asia, and South America, choosing the right window material affects not only the end-user’s energy efficiency but also the overall competitiveness of the product.In regions with high temperatures, humidity, coastal salt exposure, or large day–night temperature differences, energy performance becomes even more critical.
This makes the question “Which is more energy efficient, aluminium windows or uPVC windows?” one of the most common inquiries.Below is an analysis based on global research data combined with VIGORAWINDOWS’ export experience.
Because of its low thermal conductivity, uPVC naturally provides excellent insulation.However，modern aluminium windows can achieve good energy performance when equipped with thermal break profiles and energy-efficient glazing.
Australian Building Codes Board (ABCB) reports that uPVC has a thermal conductivity of approx. 0.17 W/m·K, significantly lower than traditional aluminium (approx. 160 W/m·K), meaning uPVC loses far less energy under equal conditions.

The Energy and Resources Institute (TERI), India, notes that in South Asian climates, uPVC windows perform 20–30% better in energy efficiency compared to non-thermal-break aluminium windows.

Dubai Electricity & Water Authority (DEWA) states that in high-heat regions such as GCC countries, thermal break aluminium windows with Low-E glass can reduce energy loss by 18–23% compared with standard aluminium windows.

These studies cover Australia, South Asia, and the Middle East—ensuring global diversity rather than Europe-/US-only sources.
VIGORAWINDOWS’ Practical Observations
Based on years of exporting to tropical and desert climates:
Residential, hotel, and apartment projects → Prefer energy-efficient uPVC windows
Commercial façades, large glazing areas, showrooms → Prefer aluminium windows
This aligns with global data and feedback from our distributors.
Even though material properties differ, real energy performance also depends on structural design, glazing type, sealing, and factory workmanship.
1) Importance of Thermal-Break Aluminium
Most modern aluminium window suppliers use thermal break designs, significantly reducing heat transfer.
At VIGORAWINDOWS, all aluminium windows are equipped with insulated profiles + double or triple glazing, suitable for hot regions in the Middle East and Africa.
2) Glass Determines 40–60% of Energy Savings
Low-E coatings, double/triple glazing, and argon gas filling all significantly improve energy performance.
When distributors ask about aluminium window price or upvc window cost, many overlook the huge impact of glass configuration—something we always explain in detail.
3) Sealing Quality Influences Indoor Comfort
Whether ordering custom uPVC window products or aluminium windows, factors such as sealing strips, welding/joint technology, and drainage design greatly affect insulation.
As both an aluminium window factory and upvc window factory, VIGORAWINDOWS maintains the following standards:
Triple EPDM sealing
Fully automated welding and precision corner injection
Certified air-tightness, water-tightness, and wind-load performance
Choosing the Right Option by Climate & Project Type
Based on VIGORAWINDOWS’ export experience in the Middle East, Africa, Southeast Asia, and South America, these recommendations help distributors improve competitiveness.
Hot, dry climates (Saudi Arabia, UAE, Kuwait)
Recommended: Thermal break aluminium + Low-E glass
Reason: Aluminium maintains structural stability under extreme heat, and thermal-break technology ensures strong insulation.
Humid tropical climates (Malaysia, Philippines, Ghana)
Recommended: uPVC windows
Reason: uPVC naturally resists heat transfer, corrosion, and salt exposure with lower after-sales risk.
High-rise apartment projects (common in South America)
Recommended: custom uPVC window or aluminium windows
Chosen based on required wind-load performance.
Both aluminium and uPVC windows can achieve strong energy efficiency. What matters is:
Whether thermal-break technology is used
Whether double/triple Low-E glass is selected
The factory’s sealing and manufacturing quality
Whether the material matches local climate conditions
From the perspective of material alone:
→ uPVC typically offers better insulation than non-thermal-break aluminium
→ Thermal-break aluminium with high-performance glazing can match or exceed uPVC performance
For overseas distributors, the real priority is choosing a supplier who can provide professional engineering solutions, reliable production quality, flexible customization, and stable pricing.
