Comparing uPVC and Timber Sash Windows
When choosing between traditional wood and modern uPVC, it is vital to think about long-lasting upkeep, expense, and thermal performance. The following table provides a direct contrast in between the two products.
Table 1: uPVC vs. Timber Comparison
| Feature | uPVC Sash Windows | Lumber Sash Windows |
|---|---|---|
| Preliminary Cost | Economical to Mid-range | High to Premium |
| Upkeep | Low (wipe tidy just) | High (sanding/painting every 5 years) |
| Lifespan | 25 - 35 years | 50+ years (with stringent maintenance) |
| Resistance to Elements | Impervious to rot and pests | Susceptible to rot, warping, and swelling |
| Thermal Efficiency | Excellent (Multi-chambered) | Good (however prone to drafts with time) |
| Authenticity | High (with woodgrain foils) | Authentic (Original) |
| Sustainability | Recyclable | Renewable/Biodegradable |
Secret Benefits of uPVC Sash Windows
The shift toward uPVC in the heritage market is driven by a number of essential benefits that deal with the historic flaws of the sliding sash design.
1. Extraordinary Thermal Efficiency
Standard sash windows are infamous for being drafty and cold. Modern uPVC sash windows make use of multi-chambered profiles that trap air, acting as an insulating barrier. When coupled with high-performance double or triple glazing, these windows can achieve an "A" energy ranking, considerably decreasing heating expenses and carbon footprints.
2. Boosted Security
