What is uPVC?
Handles & Hinges UPVC Maintenance Ltd is the UK expert in replacement parts for UPVC windows and doors. Here’s a simple explanation of what uPVC is, how it’s different from regular PVC, and why it’s ideal for windows and doors.
Definition & Properties
uPVC stands for unplasticized polyvinyl chloride. Unlike regular PVC (made flexible by adding plasticizers), uPVC is rigid, solid, and highly durable. It’s one of the most popular materials for modern building products.
- Rigid and strong — resists heat, scratching, and impacts.
- Highly weather-resistant — won’t warp, rust, blister, or rot.
- Low-maintenance — a quick wipe-down keeps it looking fresh.
- Excellent insulator — reduces heat loss and outside noise.
- Recyclable — long-lasting and can be reused at the end of its life.
Common Uses
- Window & door frames — durable, energy-efficient, and cost-effective.
- Roofline & cladding — fascias, soffits, trims — minimal upkeep outdoors.
- Pipes & plumbing — corrosion-resistant for cold water and drainage.
- Other construction — conservatories, window sills, and internal trims.
Why It’s Popular for Windows & Doors
- Durability — lasts for decades without warping or rotting.
- Energy-efficient — excellent sealing and insulation properties.
- Cost-effective — cheaper than timber or aluminium with minimal upkeep.
- Attractive finish — available in many colours and realistic woodgrain effects.
