What is the Cost of Triple Glazing?
Triple glazed windows cost about £2,000 for a 2-bedroom house on average.
Similarly, the cost of triple glazing a 4-bedroom house with 15 windows can be between £6,000 and £7,000.
For comparison, take a look at double glazing prices. A double glazed window that costs £350 will have a triple glazing price of £485.
What is Triple Glazing?
Triple glazing is a way of insulating your doors and windows, similar to double glazing. It uses three panes of glass, instead of two as double glazing does. The three panes are sealed, with gaps between them. These gaps are either filled with air or a neutral insulating gas like Argon.
The layer of air or gas acts like insulation. It prevents heat from simply being conducted out of the glass. Since glass is a good conductor of heat, this insulation makes a considerable difference. As a result, triple glazed doors and windows are excellent for retaining the heat in your home.
Studies have shown that windows can let out up to 20% of the heat in the house. As a result, your heating needs to work that much more to maintain a steady temperature. Older double glazed windows and doors, as well as single glazed fittings, are notorious for being extremely inefficient at insulating. Triple glazed window fittings, on the other hand, can effectively seal the heat inside.
As a result, your home stays at a comfortable temperature more efficiently and for longer. In fact, triple glazing is extremely popular in colder countries. However, the UK is slowly and steadily adopting it as well. The main reason for this is because it helps you save a considerable amount in heating bills. It is also quite effective at keeping unwanted noise out, so the initial triple glazing cost is a worthwhile investment for your home.
How Much Will it Cost Me To Triple Glaze My House?
There are several factors that affect the cost of triple glazing. The style of your windows and their sizes is a big aspect. Additionally, the number of windows, how many floors your property has, and the Windows Energy Ratings all play a part in the cost.
Your triple glazed windows price will be higher than the price of double glazing. For example, a window with double glazing might cost you around £350 to buy and install. Your triple glazed windows price, though, will cost you in the region of £485.
If you are looking for general triple glazed windows price estimates, here is a rough idea of what you might spend:
- For a 2-bedroom flat with four windows – £1,940
- A 2-bedroom terraced property with 5 windows – £2, 425
- In case of a 2-bedroom semi-detached house with 7 windows – £3,395
- For a 3-bedroom semi with 9 windows – £4,365
- A 3-bed detached property with 12 windows – £5,820
- For a 4-bedroom detached house with 15 windows – £7,275
It is important to note that these are very general estimates. You can only get a more accurate triple glazed windows cost after a technical survey. Moreover, the size and style of your windows will affect the price as well. Additionally, other factors like the type of glass, colour and finish, and type of hardware also affect the cost of triple glazing.
It is also interesting to note that the more windows you have, the more cost-effective your triple glazing total price will be. This is because the installer can earn a higher profit with more windows on the same property. It is easier for him to set up 15 windows in one property than 1 window in 15 properties.
