Double glazed windows originated in Victorian Scotland and was first commercially developed in the 1930s. In the UK, it became widely adopted during the 1970s and 1980s, with significant growth driven by energy efficiency concerns.
UK building regulations now require new windows to be at least C-rated for energy efficiency, with many modern units achieving A++ ratings from the British Fenestration Rating Council (BFRC).
By 2021, approximately 93% of UK homes had some form of double glazed windows, demonstrating its widespread adoption and importance in modern home design.
The main materials used for double glazing windows are:
Each material has its own advantages and considerations in terms of cost, maintenance, durability, and aesthetic appeal. The choice often depends on factors such as the homeowner’s budget, desired style, and specific requirements of the property.
Timber (wood) offers the best thermal insulation for double glazing frames. Timber is a natural insulator that absorbs and retains heat, making it the most energy efficient material for window frames. Wood’s cellular structure, consisting of millions of tiny hollow cells filled with air, creates a significant barrier to heat transfer, slowing down the movement of heat in or out.
However, it’s important to note that while timber provides superior insulation, it comes with some trade-offs:
Other materials also offer good thermal insulation, though not quite as effective as timber:
When considering overall energy efficiency, it’s crucial to look beyond just the frame material. Factors such as glazing type (double or triple), low-emissivity (low-E) coatings, and inert gas fillings between panes also play significant roles in a window’s overall thermal performance
