Double-Glazing Cost - Factors to Consider

Several factors affect the cost of double-glazing a 3-bed house, including window types and styles, frame materials, energy efficiency ratings, and additional features.

Standard double-glazing typically consists of two glass panes with a space between them filled with air or an inert gas, such as argon, for insulation purposes.

3-Panel Double-Glazed Window

Upgrades for standard double-glazing include triple-glazing, offering additional insulation and noise reduction.

High-performance Low-E coatings further enhance insulation and solar control.

uPVC windows provide many benefits, including:

  • Durability and long-lasting quality due to being made of unplasticised polyvinyl chloride
  • Cost-effectiveness, as they can be up to three times less expensive than wooden frames
  • Market-leading energy efficiency, helping to reduce heating bills
  • Recyclability allows the plastic to be repurposed when the windows are taken out.

Window Types and Styles

As you look at other houses on your street, you will notice that many properties have different window styles and aesthetics, each giving off its own uniqueness and personality.

This can help you decide on what style you like the most and what would suit your own home.

The type and style of window, such as casement, sash, or bay windows, can influence the cost of double-glazing.

The cost of double-glazing for a white uPVC casement window varies widely. It typically ranges from £600 to £1,100 per window, with the material and any additions to your windows affecting this price.

Factors such as size, glazing design and the number of windows being replaced in the property can influence this cost. A double-glazed sash window is usually much pricier than a casement one. It can cost up to 50% more.

Improvements for double-hung windows include insulated frames and high-performance glass. Casement windows can be upgraded with multi-point locking systems and energy-efficient glass.

The advantages of casement windows include their robustness, safety, and energy efficiency.
