Windows affect light, heat, noise and security. UPVC and aluminium are the two most popular modern choices.
UPVC windows
Good thermal and sound insulation, tight sealing and no painting or rusting. They suit coastal and humid areas and are usually priced mid-range.
Aluminium windows
Slim frames, a wide range of colours and strong spans for large glass areas. Choose thermal-break profiles to reduce heat transfer.
Which should you pick?
- Choose UPVC for noise reduction, humidity and low maintenance
- Choose aluminium for large openings and a slim, modern look
- Use good hardware and double-glazing in either case for best results
