What frame material means for your windows: how it affects durability, energy bills, maintenance, etc.
uPVC: Pros & Cons
- Great insulator, keeps temperature stable inside
- Low maintenance; doesn’t rust, rot, or require frequent painting
- Cost-efficient initially
- Possible drawbacks: weight limits for large spans, fewer sleek profiles, less strength than metal in some cases
Aluminium: Pros & Cons
- Slim frames → larger glass area → more daylight, modern aesthetic
- Strong & durable; better for structural demands and large windows
- Corrosion resistance if properly coated
- Drawbacks: higher upfront cost, potential heat transfer unless thermal breaks used, may require more technical installation
Comparisons: Key Metrics
- Thermal insulation (uPVC often better)
- Aesthetics & design flexibility
- Lifespan & durability
- Maintenance costs over time
- Upfront vs lifetime cost
Which to Choose Based on Situation
- Hot climate vs moderate
- Big floor-to-ceiling windows vs smaller ones
- Budget constraints vs design priorities
