UPVC vs Aluminum windows in Lebanon.
Choosing window frames in Lebanon usually comes down to UPVC and aluminum. Here's how they compare across the metrics that matter for villas, apartments, and commercial projects.
| Criterion | UPVC | Aluminum |
|---|---|---|
| Thermal insulation (U-value) | 0.8 – 1.3 W/m²K | 5.0 – 7.0 W/m²K |
| Coastal salt resistance | Excellent | Corrodes over time |
| Sound reduction | Up to 45 dB | 25 – 32 dB |
| Maintenance | None — soap & water | Repainting / reseal |
| Lifespan | 40+ years | 20 – 25 years |
| Cost (mid-range) | Competitive | Similar to UPVC, higher for thermal-break |
Common questions.
Is UPVC better than aluminum for windows in Lebanon?
For most homes — yes. UPVC insulates roughly 5× better, doesn't corrode in coastal salt air, and is significantly quieter. Aluminum still wins for very large, narrow-frame architectural openings.
Does UPVC yellow or warp in the Lebanese sun?
Quality UPVC profiles are UV-stabilized for Mediterranean climates and carry 10-year warranties. We only fit profiles tested for hot-climate use.
How much energy does UPVC save?
Compared to single-glazed aluminum, owners typically see a 25–40% drop in HVAC energy use across a full year in Beirut and Mount Lebanon.
Are UPVC windows secure?
Yes — multi-point locking, steel-reinforced cores, and laminated glass options exceed the security of standard aluminum sliders.
