Window styles explained

Why window choice matters

Which window you choose affects more than how your home looks. The right style can boost energy efficiency, improve security and even add value when you sell. If you’ve spotted drafty frames or outdated designs, it might be one of the top signs it is time to replace your windows.

Key criteria for selection

When you’re weighing up options, focus on five core factors:

  • Energy performance: U-values and glazing levels
  • Security: locks, toughened glass and hardware
  • Natural light and airflow: size, placement and operation (the impact of window placement on natural light and ventilation)
  • Aesthetic fit: period character or contemporary lines
  • Budget and lifespan: upfront cost versus long-term value

Casement window features

How they work

Casement windows hinge at one side and swing open like a door. Most hinge inwards for easy cleaning, but outward-opening options exist if space allows (Which?).

Pros and cons

  • Pros
  • Excellent airflow when fully opened
  • Simple seal reduces draughts
  • Wide material choices: uPVC, timber, aluminium
  • Cons
  • Outward opening can catch on external features
  • Hinges need occasional lubrication

Cost and lifespan

  • Typical cost: £500–£1,250 per window (Checkatrade)
  • Lifespan: 10–20 years with proper maintenance
  • Energy efficiency: good U-values when double or triple glazed

Sash window features

How they work

Sash windows slide a weighted pane up or down to open. Modern designs use double glazing and counterweights or spring balances to improve insulation and ease of use (Which?).

Pros and cons

  • Pros
  • Classic look suits period properties
  • Variable opening height for airflow control
  • Cons
  • Weight and balance mechanisms need servicing
  • Potential for more air leakage if worn

Cost and lifespan

  • Typical cost: £700–£1,500 per window (Checkatrade)
  • Lifespan: 15–20 years with regular upkeep

Tilt and turn window features

How they work

Tilt and turn windows offer two opening modes. You tilt them inward at the top for secure ventilation, or turn the handle to swing fully inward for cleaning and escape routes (Which?).

Pros and cons

  • Pros
  • Flexible airflow options
  • Strong multi-point locks boost security
  • Cons
  • Slightly higher hardware cost
  • Inward swing may limit interior layout

Cost and lifespan

  • Typical cost: £600–£1,400 per window (Checkatrade)
  • Lifespan: 10–20 years when well maintained

Other popular options

Bay and bow windows

These projecting styles create extra space and panoramic views.

  • Bay window cost: £1,100–£4,000
  • Bow window cost: £1,500–£5,000+
  • Pros: architectural interest, extra seating or storage
  • Cons: higher structural and installation costs (Checkatrade)

Sliding windows

Horizontal panels glide past each other on tracks.

  • Cost: £600–£1,400 per unit (Checkatrade)
  • Pros: space-saving, easy operation
  • Cons: track maintenance, limited opening width
