08 Mar Weather Resistance of UPVC Windows and Doors in Blackpool and Preston
Introduction
Blackpool and Preston experience some of the UK’s most challenging weather conditions—coastal winds, heavy rainfall, salt spray, and damp winters. For homeowners in these areas, choosing the right windows and doors is crucial to ensuring durability, energy efficiency, and long-term protection.
UPVC (unplasticized polyvinyl chloride) windows and doors stand out as the best solution for withstanding these harsh conditions. Unlike traditional materials like wood or aluminium, UPVC is specifically designed to resist corrosion, moisture damage, and extreme temperature fluctuations.
In this blog post, we’ll explore why UPVC is the most weather-resistant option for homes in Blackpool and Preston, covering:
- Resistance to Coastal Salt & Corrosion
- Protection Against Heavy Rain & Dampness
- Wind Resistance for Stormy Weather
- Thermal Stability in Extreme Temperatures
- UV Protection Against Sun Damage
- Long-Term Durability in Harsh Climates
- Why UPVC Outperforms Wood & Aluminium
1. Resistance to Coastal Salt & Corrosion (Blackpool’s Biggest Challenge)
The Problem: Salt-Laden Air
Blackpool’s coastal location means homes are constantly exposed to salt spray, which can:
- Corrode metal frames (aluminium/steel windows deteriorate faster).
- Cause wood to rot due to prolonged moisture exposure.
How UPVC Performs Better
✅ Non-corrosive – Unlike metal, UPVC doesn’t rust or degrade.
✅ No rotting or warping – Unlike wood, UPVC won’t absorb moisture.
✅ Easy to clean – Salt deposits can be wiped off without damage.
“Since switching to UPVC, my windows no longer show rust stains from the sea air.” – Blackpool homeowner.
2. Protection Against Heavy Rain & Dampness (Preston’s Rainy Climate)
The Problem: Persistent Rainfall
Preston averages 1,300mm of rain per year, leading to:
- Wooden frames swelling and warping.
- Mould growth in poorly sealed windows.
- Condensation issues with single-glazed units.
How UPVC Handles Moisture
✅ 100% water-resistant – No absorption, preventing rot.
✅ Advanced drainage systems – Built-in channels prevent water pooling.
✅ Airtight seals – Reduces condensation and dampness.
Pro Tip: Opt for tilt-and-turn UPVC windows to improve ventilation and reduce condensation.
3. Wind Resistance for Stormy Weather
The Problem: Strong Coastal Winds
Blackpool and Preston experience frequent gusts over 50mph, which can:
- Rattle poorly fitted windows, causing drafts.
- Damage weak frames over time.
How UPVC Stands Up to Storms
✅ Multi-chambered design – Reinforced for high wind resistance.
✅ Strong welded joints – No weak spots for air leakage.
✅ Impact-resistant glazing – Optional toughened glass for extra security.
“After a storm, my old wooden windows rattled, but my new UPVC ones stayed completely solid.” – Preston resident.
4. Thermal Stability in Extreme Temperatures
The Problem: Cold Winters & Occasional Heatwaves
- Preston’s winters drop below freezing, requiring strong insulation.
- Blackpool’s summer sun can warp cheap materials.
How UPVC Maintains Performance
✅ Low thermal conductivity – Keeps heat in during winter.
✅ Doesn’t expand or contract – Unlike metal, which can warp in heat.
✅ Double/triple glazing options – Improves insulation further.
Fact: UPVC can reduce heat loss by up to 30% compared to single-glazed windows.
5. UV Protection Against Sun Damage
The Problem: Fading & Brittleness
Prolonged sun exposure can:
- Fade coloured window frames.
- Make plastic brittle over time (if low-quality).
How High-Quality UPVC Resists UV Damage
✅ UV-stabilised coatings – Prevents colour fading.
✅ Durable material – Won’t crack or discolour over time.
✅ Wider colour options – Unlike wood, no need for repainting.
Best Choice: Foiled UPVC (colour baked into the material) lasts longer than painted finishes.
6. Long-Term Durability in Harsh Climates
Why UPVC Lasts Decades in Blackpool & Preston
- No rust, rot, or corrosion – Unlike metal and wood.
- Minimal maintenance required – No sanding, painting, or sealing.
- 20-30 year lifespan – Far outlasts traditional materials.
Case Study: A Blackpool seafront property with 30-year-old UPVC windows still performing well with no structural damage.
7. Why UPVC Outperforms Wood & Aluminium
| Feature | UPVC | Wood | Aluminium |
| Salt Resistance | ✅ Excellent | ❌ Poor (rots) | ❌ Corrodes |
| Rain Resistance | ✅ Waterproof | ❌ Swells/warps | ✅ Good (but can leak) |
| Wind Resistance | ✅ Reinforced frames | ❌ Weak joints | ✅ Strong but conducts cold |
| Maintenance | ✅ Almost none | ❌ High (painting, sealing) | ✅ Low (but can corrode) |
| Lifespan | ✅ 25+ years | ❌ 10-15 years (with upkeep) | ✅ 20+ years (if coated) |
Final Verdict:
- UPVC is the best all-rounder for Blackpool & Preston’s weather.
- Wood requires high maintenance and fails in damp conditions.
- Aluminium is strong but can corrode near the sea.
Conclusion: UPVC Is the Best Weatherproof Choice
For homes in Blackpool and Preston, UPVC windows and doors provide:
✔ Superior salt and corrosion resistance (perfect for coastal areas).
✔ Excellent rain and damp protection (ideal for Preston’s climate).
✔ Wind-resistant strength (withstands storms).
✔ Thermal stability (reduces heating bills).
✔ UV protection (no fading or brittleness).
✔ Low maintenance & long lifespan (saves money over time).
