You have decided to make some much-needed improvements to your home, but how can you be certain that upgrading your existing windows to triple glazing is the right solution for you?
Let’s look at a few common questions about triple glazing to determine if it is the right improvement for your home.
An energy efficient home is less costly to run. Especially in a country where temperatures drop significantly during the winter months, the cost of heating a home can be substantial.
A badly insulated home leaks heat in the same way as a cup of coffee that is left on the table. 25% of heat generated is lost through the roof; 25% through the windows, 15% through the floor and a massive 35% through the walls. Especially older homes have insufficient insulation because thermal insulation didn’t become a building requirement until the 1970’s. Large amounts of the energy spent to heat the average 3-bedroom home is lost because of poor insulation. This means that your home may be leaking heat, which directly translates into leaking money.
Some of these elements, like roofs, can be insulated fairly quickly and inexpensively. By installing mineral wool or similar insulation materials, you can quickly ensure that you won’t be losing any more heat there.
Insulated boards can also be used where there is a roof conversion or loft space. While more expensive, it will certainly improve the heat retention capabilities of those areas.
Where roof areas are not accessible, you can have blown insulation applied by a professional.
Floors are another area where you can get the benefits of heat insulation without too much effort. Ensure that you don’t have any gaps between floor boards and that the skirtings are all intact. It is essential to keep the external air vents open where wooden floor are concerned, in order to prevent moisture building up underneath the floor.
Walls are a bit more costly to insulate, but since they account for more than a third of total heat loss, it makes complete financial sense to address this area.
As with inaccessible roof spaces, cavity walls can be insulated with blown insulation. Solid walls however loose double the amount of heat of cavity walls, and have to be clad with thermal cladding to create a heat barrier.
Windows can contribute to 25% heat loss in your home, so getting them insulated should really be a priority for any home-owner. Triple glazing reduces heat loss by 50% over double glazing and can save you up to £100 every year in heating costs alone.
Triple glazing offers superior heat insulation, so anyone wanting to improve their property’s energy consumption and subsequent energy rating will benefit from an upgrade.
But it’s not only the cost of heating your home that will be positively impacted by the installation of triple glazing; it’s also the level of comfort in your home. Cold spots and draughts as well as interior condensation are a common problem with older windows. The technology used in triple glazing is so advanced that interior condensation can now be completely eliminated from your home.
Cold spots usually occur when there is significant heat loss through a window, causing the area around the window to be much cooler than the rest of the room. R-value is a measure of heat transference through a window. Standard single-pane windows have an R-value of 1 and double glazing has an R-value of 3. Triple glazing has an R-value of 5, resulting in a much more stable interior temperature.
Test have shown that a room with triple glazing has window surface temperatures of 18 degrees Celsius when the room is heated to 21 degrees Celsius. The composition of the window unit with 3 panes of glass and 2 Krypton gas-filled cavities, ensures that the least amount of heat can escape to the outside.
Because the window is also manufactured as a single, insulated unit, the chance of draughts occurring around the window are minimal. A professional installer will also guarantee their workmanship and ensure that the window frame is properly sealed after installation.
Triple glazing has the ability to significantly increase the selling price of your property. According to figures released by the Department of Energy and Climate Change (DECC), making energy saving improvements to your home can increase its value by an average of 14%, and up to 38% in some parts of England.
A good Energy Performance Certificate (EPC) is a covetable commodity in the housing market. A band G home that is elevated to band E, or a band D home elevated to band B, could mean an additional £16,000 on the sale price of your home.
It is estimated that in some parts of the North East, energy efficient improvements that elevate from band G to band E, add £25,000 and in the North West, improvements can add up to £23,000 to your home’s value. With the installation of triple glazing in the average 3-bedroom, 15-window home coming in at less than £8,000, that is a sizeable return on investment.
Since 2007, rental properties are also required to have an EPC. A prospective tenant and property agent are both within their rights to request an EPC from a home owner, to better understand the expenses related to running of that property.
But environmental responsibility does not only belong to the landlord. Many lease agreements now include a clause on the responsibilities of the tenant as well, requiring them use water responsibly, recycle, or managing the property in an energy efficient way.
Triple glazing will significantly improve your home’s EPC which means you are also able to get a higher rental income from the property.
Upgrading your existing double glazing to triple glazed windows is a sizeable investment. But when looking at that cost, it is important to consider all the facts.
To install double glazing in an average home in the UK, consisting of 3 bedrooms and 15 windows, will cost roughly £5,000. This installation will cut £65 off your annual heating bill when compared with single glazing, which equates to about 10% of your total heating bill. At that rate, it will take you 77 years to get your investment back.
Triple glazing costs around 30% more to install at £7,275. This added cost will give you an additional annual energy saving of 15% on top of the 10% mentioned above, which comes down to £162.50. This means that it will take you 45 years to get your investment back, which is already much faster than with double glazing.
The above figures show that while triple glazing will give you a significant annual cost saving on your energy bill, it will take many years for you to recuperate your investment. If your intention therefor is to spend money to save money, then triple glazing might not be the best option.
What does make complete sense though, is if you intend to use your home’s increased value to your benefit: when you are renovating to sell; to increase your home’s Energy Performance Certificate; to increase the level of comfort in your home; or to be able to increase rental income from a secondary property, then triple glazing is an easy and profitable choice.
We all have to do our bit to reduce the consumption of natural resources and its impact on our environment. Triple glazing and domestic thermal insulation will make a substantial difference in your home’s carbon footprint, the value of your home and your enjoyment of it.
