Double Glazing Types

On average double glazed windows require replacement every 20-25 years so there is a good chance this will be a task you will need to complete if you live in a property for any duration of time. Sealed Double Glazed units become unstable after 20 years and the seal leaks allowing moisture and misting between the two panes of glass. When choosing replacement windows its important to consider the frame material, below we present a guide to the most popular choices on offer.

1. UPVC
UPVC window frames are the most popular choice due to affordability, energy efficiency and moisture resistant. uPVC windows however often come in a limited range of colours, normally white.

2. Wooden
Wooden window frames are popular to give a traditional look to your home. Wooden windows are extremely energy-efficient as wood is a superior insulator. However wood is both a costly and high maintenance option.

3. Composite
Composite frames combine an exterior cladding (usually aluminium) with and wooden core. These frames are high-performance energy-efficient and stable. They can be manufactured to suit any look and do not require regular maintenance. However they are more expensive to purchase than other options.

4. Fiberglass
Fibreglass is an extremely option, and offers superior strength and resists cracking and fading longer than uPVC. Fiberglass offers superior energy-efficiency and is less likely to expand or shrink. However its a more expensive option to uPVC and is higher maintenance.

5. Aluminum
An inexpensive solution they requires almost no maintenance and is strong and lightweight. However aluminum requires nearly no maintenance and is very light and strong. However Aluminium is a poor insulator and the least energy efficient type of frame and some people find them unattractive.

Once you have chosen the frame that best suits your requirements you need to choose which type of glass you require. The British Fenestration Ratings Council (BFRC) provides an official window energy ratings table, ranging from A to G, with A rating offering the greatest energy efficiency. However there are other options you might consider alongside energy saving such as acoustic glass if noise reduction is your primary need or toughened glass (now mandatory in some areas of the home) if safety and security is a concern.
