How much can new windows save on energy?
It’s well known that poor insulation and an overall aging home are the main causes of heat loss. However, it is thought that up to an eye-watering 40% of that heat is lost through the windows alone. A window is more likely to be losing this amount of heat if it is an old unit which is usually going to be single glazed with a worn frame sealing, and therefore poorly insulated, or you may even have a newer but poorly installed unit. Whatever it is, we can be sure that any issues such as these will be wasting energy and heating, and therefore wasting your money on unnecessarily high energy bills.
If you are looking for ways of cutting costs in your energy or utility bills, then you will definitely want to consider the suitability of your current windows for efficiency and energy saving. With an ever-growing concern for the environment and the cost of energy in today’s society, it has almost become a necessity for all homes to have energy-efficient windows installed. In an attempt to curb wasted heat and energy which, at the end of the day, is a significant factor in both the issues mentioned.
Of course, what you are possibly losing at the moment in energy savings, and what you could save in the long-term, depend quite heavily on the type of property you live in. For example, if you were to live in a single-glazed, mid-floor apartment, you will be less likely to lose as much heat as you would in a detached or semi-detached house with the same style window. This could mean that if these properties were to have new window units installed, specifically double-glazed with appropriate insulation, you may see significant savings compared to each other, but may possibly even itself out due to savings already being made beforehand. The significance may also depend on household income, as a little can go a long way in some cases.
In the short term, the thought of having new windows installed can be quite daunting, especially if you have any preconceived ideas of the cost and any disruptions to home life during the installation process. Both of these variables will depend on materials used, the number of windows on the property, and the company or tradesman you hire to carry out the work. Be sure to shop about and do some research on these areas before diving into anything permanent.
An example of possible window materials:
- Wooden frame – an excellent insulator and can be pleasing on the eye, but requires regular maintenance and can be expensive. A popular choice for older homes.
- UPVC frame – not the most aesthetically pleasing material, but it is low cost, low maintenance, highly durable, and highly efficient. Making it the country’s most popular choice for window frames.
Comparing different types of domestic property being upgraded to double-glazing from single, these are the possible savings you could expect each year:-
- Mid-floor flat – up to £40
- Bungalow – up to £75
- Semi-detached – up to £100
- Detached – up to £135
We do highly recommend installing new windows if you have not already – at least in the last 10 years. Even if the upfront costs can be off-putting, you will definitely see the rewards in the long term.
