There is also a whole range of different materials that your window frames can come in, including uPVC, wood, and steel, all with their own negatives and positives.
- Wood is a renewable source for those concerned about their carbon footprint but will need to be treated regularly to keep it in good condition.
- uPVC is tough and needs little maintenance other than wiping clean; some do not like the look of it, but there are some really good imitation wood finishes to be found if this is a concern.
- Steel is long-lasting and tough, and is a great choice in areas of strong sunlight as uPVC frames can expand in these conditions.
Windows may also have gasses such as argon in the space between the panes which makes them more efficient, and many products will have coated glass called Low-E that does not affect the look of the window but does increase the efficiency of the unit.
