All new windows come with an energy efficiency rating from A to G. A is best, while G is the lowest rating. Anything above C is considered good, but these days most companies will be able to supply you with A-rated windows to maximise your energy efficiency.

Secondary glazing
Replacing your inefficient windows is one of the best home improvements you can make to reduce your energy bills and cut carbon emissions.
Most homeowners will look towards double glazing when replacing their old windows, but listed buildings and properties in Conservation Areas often won’t be granted permission.
This is where secondary glazing comes in, as it doesn’t change the external look of the property and instead a second pane is fitted on the inside of the first, with an air gap to heighten energy efficiency.
Of course, this isn’t as efficient as a double glazed unit but still stands to save homeowners plenty of money every year on their energy bills.
Secondary glazing has become much more popular in recent years, as it shares a lot of the same qualities as double glazing, but comes at a cheaper cost.
Benefits of secondary glazed windows

The two panes of glass will work together to lock heat in your home, ensuring you needn’t turn up the temperature to keep warm.
Add to your home’s security

Slash your home’s carbon footprint

The effectiveness of secondary glazing will be directly affected by the gap between the two panes of glass, normally recommended at 100mm. Sound insulation will also improve with the glass’ thickness.

Secondary glazing FAQs
Windows, being a very crucial feature in every home, are one of the things you simply can’t afford to ignore in your home. Having a good understanding and solid knowledge of your windows’ components like the window sash will help you stay up to date with them and able to identify any minor mishaps early on before it leads to a much bigger problem. So what exactly is a window sash?
Well without much fuss, a window sash is simply that part of your windows that’s able to open and close. And there could as well be more than one window sash that’s operable depending on your window’s type. Window sash usually possess a very basic design as well as structure. What’s more? This section of a window happens to be a frame that’s designed in such a way to make for easy placement inside the whole window casement. You’ll discover inside the sash frame, the window glass alongside any framework possessed by your window which includes grids.
Usually, the sash is fitted into the frame of the window on a runners’ set in such a way that allows for both upward and downward movements. And finally, the window sash’s frame typically comes with a locking system which provided for extra safety and security.
The window sash is a vital feature that can determine the durability and overall performance of the windows. In the event whereby your window sash is malfunctioning, it can result to numerous problems which includes both drafts as well as leaks. As a result, it’s very important to keep your window sashes in a great working condition as failure to do so will make opening and closing your windows a really difficult task.
As well as keeping your home warmer and reducing noise, you’ll notice a saving on your energy bills from installing double glazing. If you install A++ rated windows in your home after having single glazing, you could save up to £120 year on your energy bills. The Energy Saving Trust has more information.
Ultimately the double glazing company you use is responsible for the quality of work and to ensure your windows are of an excellent standard. This is why it’s important to get a warranty and use a Fensa registered installer. If problems emerge within a couple of years then it’s likely the installation was of a poor standard.Contact the double glazing company and have the issue repaired or new windows replaced. This doesn’t matter if you received a discount of free windows as part of the deal. As long as you entered into a contract the company is obliged to restore the windows.
One of the essential factors that makes a home truly a home is the convenience and comfort it provides us. As a result, we usually have a long to do list comprising things that come together to make sure our home is comfortable with ambient temperature at the very top of the scale of preference. After all, no matter how greatly designed your furniture and home decor is, it probably would amount for nothing if the temperature is either too hot or too cold. Some of the most common ways we incorporate to make the temperature a lot more conducive and warm during the winter months is by installing air conditioning system or through top notch insulation materials, but the fact still remains that a lot of heat would escape through the doors and windows. And that’s exactly the use of double glazing. So how exactly does double glazing work?
Double glazing basically works by preventing the escape of air and trapping it between two panes of glass. It’s the trapped air which serves as an insulation barrier which delivers 3 major functions. First and foremost, it stops the escape of heat through the window as the barrier created insulates the room from varying air temperatures at both sides of the glazing unit. The second major function is the double glazing works to keep down noise pollution coming from outside. While the third major function of double glazing I the fact that it helps minimize condensation which usually occurs on the single glazed windows’ inside as the cold outside air works to cool the warm air inside the house. When you install a double glazing window, the insulation barrier generated will work to stop the air temperature transmission which ultimately helps prevent the occurrence of condensation.
The energy efficiency of windows is measured using ratings, varying from A, the most efficient, to G, the least efficient. This scheme is run by the British Fenestration Council (BFRC). To comply with Building Regulations you’ll need windows of energy efficiency at least level C.
Are you looking to replace your old window for a new double glazed window and wondering what it’s going to be the cost? Well, the double glazed windows market is a very competitive one in the UK with varying prices across the country. Therefore, if you shop around you’re most likely to find something that’ll fit your budget both products and quality wise.
As you would have expected, the more windows you required the more money you are going to spend. However, the cost per window is likely going to be lower depending on the number of windows you purchase. Several double glazed windows come with a 10 year warranty but it’s advisable to also obtain a solid workmanship warranty which provides coverage for any potential problems for a good period of time upon installation.
To determine the cost of double glazed windows, there are so many things to put into consideration that just the primary dimensions of the window itself. Other factors that works to decrease or increase the cost of the project includes the frames’ quality as well as the material used. For example hardwood can be quite high priced when compared to uPVC.
The number of opening windows within the frame can also play a huge role in the cost of the windows as well as the type of the glass. The cost of a double glazing window usually ranges between £100 to £3,200 per window, depending on the available options.
To have a more accurate estimate of the cost of a double glazing window, you’ll need a obtain a survey from a double glazing installer who can take into account any possible complications that may arise when installing your windows while also giving an advise on the most suitable window style for your property.
These days, buyers expect homes to have double glazing. People recognise the benefits of installing double glazing, so if you don’t have it installed you should consider it. You’ll increase your property’s value and give it a better chance of selling faster, since single glazed properties are also more likely to have problems with damp and mould which could put buyers off.
