Wood Windows vs PVC Windows: 2025 Comparison
Detailed comparison between wood and PVC windows. Which is better in terms of thermal insulation, lifespan, cost, aesthetics and environment?
Wood Windows vs PVC Windows?
Window selection directly affects a home's energy efficiency, aesthetics, and long-term cost. In this article, we compare wood and PVC windows across 7 criteria.
1. Thermal Insulation
Wood windows are naturally excellent insulators. Thermal conductivity (λ) is 0.13 W/mK, below PVC's 0.16 W/mK. Modern wood windows can achieve Uw 0.8 W/m²K.
PVC windows provide good insulation but steel reinforcement inside profiles creates thermal bridges. Typical Uw value is 1.0-1.3 W/m²K.
Winner: Wood (40% better insulation)
2. Lifespan
Wood windows: 80-100+ years with proper maintenance. Norwegian stave churches have stood for 800+ years.
PVC windows: 25-35 years. After that, profiles yellow, become brittle, and need replacement.
Winner: Wood (3x longer lifespan)
Conclusion
If you seek quality, aesthetics, environmental responsibility, and long-term value, wood windows win by a clear margin.
