Window Types &
Materials Guide

The three most common window materials are uPVC, aluminium, and timber. uPVC is the most cost-effective, offering excellent insulation and low maintenance. Aluminium provides a modern, sleek look with slim frames and high durability. Timber offers traditional craftsmanship, ideal for period properties, with natural insulation and eco-friendly qualities.

uPVC and aluminium windows both provide good energy efficiency, often with A-rated ratings standard. Timber also insulates well naturally but may require more maintenance to maintain performance over time.

Casement windows are the most popular for modern homes, known for easy operation and good ventilation. Sash and heritage-style windows are preferred in period properties and conservation areas for their authentic appearance and vertical sliding operation.

Yes. There are balanced options for using uPVC windows in period homes that consider planning permissions and aesthetic requirements, though timber windows are often preferred for conservation areas due to traditional character.

Aluminium windows offer a contemporary appearance with ultra-slim frame profiles, allowing maximum glass area and exceptional longevity, making them suitable for modern design preferences.

Timber windows need seasonal care including cleaning, repainting or staining, and occasional professional restoration to maintain their natural insulation properties and appearance.

uPVC windows generally start from around £300 per window installed, aluminium from £500, and timber from £600, depending on size, style, and installation complexity.

Installing a single standard window typically takes between 1 to 2 hours. Full installation for an average three-bedroom house often takes 1 to 2 days. Complex designs or multiple windows may extend the timeframe up to 3 to 5 days.

Consider ventilation needs, ease of cleaning, the architectural style of your home, and any planning or conservation regulations if in a heritage area.

Yes. Acoustic windows with specific glazing and seals help reduce noise ingress, suitable for homes near busy roads or noisy environments.
