Glasgow gets a lot of rain. If you're investing in a deck, you need a material that can handle it. Timber decking looks beautiful when new, but Scotland's climate can be brutal on wood. Composite decking has become increasingly popular — and for good reason. Here's an honest comparison to help you decide.
The Glasgow Climate Problem
Glasgow averages over 1,200mm of rainfall per year — significantly more than London. That constant moisture is the enemy of untreated timber. Wood decking in Scotland typically needs treating every 1–2 years to prevent rot, warping, splitting and the dreaded green algae that makes it dangerously slippery.
Side-by-Side Comparison
| Factor | Composite | Timber |
|---|---|---|
| Lifespan | 25+ years | 10–15 years (with maintenance) |
| Maintenance | Occasional wash only | Annual staining/sealing |
| Slip resistance | Non-slip surface | Can become slippery when wet |
| Splinters | None | Common as wood ages |
| Eco-credentials | Made from recycled materials | Natural, but requires treatment chemicals |
| Initial cost | Higher upfront | Lower upfront |
| 10-year total cost | Lower (no maintenance costs) | Higher (ongoing treatment) |
