Accoya® vs. Traditional Timber: The London Homeowner's Guide
When restoring period properties in London, material choice is the difference between a 10-year fix and a 50-year investment. Here is how Accoya® stacks up against traditional joinery timbers.
| Performance Factor | Accoya® Timber | Hardwood (Oak/Sapele) | Softwood (Pine) |
|---|---|---|---|
| Expected Lifespan | 50+ Years (Above ground) | 30-40 Years | 10-15 Years |
| Swelling & Shrinkage | Minimal (75% less than others) | Moderate (can stick in winter) | High (prone to warping) |
| Maintenance Cycle | 10-12 years (Paint lasts longer) | 5-7 years | 3-5 years |
| Sustainability | Cradle-to-Cradle Gold Certified | Variable (Slow growth) | Standard FSC |
| Best For... | Heritage Windows & Bi-folds | Heavy-duty Entrance Doors | Budget-conscious repairs |
Expert Insight: Is Accoya® the right choice for your project?
