Our A-rated double glazed windows

Not all double glazing is equal when it comes to cutting the heat loss from your home. An energy-efficiency rating system is applied to all double glazing products to measure how effective they are at reducing heat loss.

Some standard double glazing windows may, for example, start at a C rating and offer some level of protection. However our EcoDiamond™ windows are A-rated. As such, they are actively recommended by the Energy Saving Trust for their excellent energy efficiency properties. You can find out about Energy Saving ratings here.

The Window Energy Rating is calculated by an organisation called the BFRC (British Fenestration Rating Council). They are responsible for making sure a window is correctly classified from A+ to G, with A+ being the highest rating and G being the lowest rating. They calculate it based on the following properties of a window:

  • Heat loss (the 'U' value): how much heat your window transfers
  • Air leakage (the 'L' factor): how penetrable they are to the air
  • Solar gain (the 'G' value): how much they maximise the heat from the sun

If maintaining a comfortable temperature in your home and saving a few hundred pounds a year on heating bills is important to you, then you should consider choosing a window that has an A-rating so you’re getting the maximum benefit.

The benefits of double glazing

Double glazing has a number of benefits over single glazed windows for both you and your home. Installing new or replacement secondary glazing with Safestyle can reduce noise pollution, increase heat retention and improve your window security, with a choice of Pro-Linea™ locking handle options. The double glazing cost can also be a worthwhile investment, as it also helps to improve the value of your property.

Peace and quiet at home

Banish noise pollution from your home with secondary double glazing. Sound travels at a speed of over 700 miles per hour and when this hits a single glazed window, this pressure vibrates the pane of glass and passes the noise into your home. With double glazing, the sound either hits a sealed frame or the vibrations are disrupted by a pocket of Argon gas between the two sheets of glass.

Our double glazed UPVC window options can reduce sound by as much as 31dB, which is like turning the volume of normal speech down to a quiet whisper.



Insulate and improve your energy efficiency

Our EcoDiamond™ windows are recommended by the Energy Savings Trust and differ from standard double glazing. The inner pane is designed to reduce heat loss, while the outer pane allows solar heat to penetrate into your home.

Safestyle windows are sealed precisely and include a 16mm gap between the double glazed glass panes, filled with Argon gas to create a superior insulating barrier. Upgrading your double glazing has the potential to save energy and cut your heating bills by over £285 a year.

Double glazed windows FAQs

What is double glazing?

Double glazing refers to the use of two panes of glass in a window, often filled with a gas such as argon between the panes to add as an insulator. The reason so many people choose double glazed windows is that it can make such a big difference to their home in terms of reducing heat loss and energy bills.

How much does double glazing cost?

The cost of your new windows or replacement double glazing will depend on your specific requirements and design preferences. However, the benefits of double glazing makes this a worthwhile investment, as they can improve your home’s energy efficiency and increase the value of your property.

At Safestyle, we also offer a price promise and will beat any like-for-like quote. To find out how much your double glazed windows will cost, request a free, no-obligation quote today.

How long will my double glazing last?

All Safestyle products are manufactured to the highest of standards in our state-of-the-art UK production facility, rigorously tested and installed by expert fitters. That’s why we’re confident in offering a 10-year guarantee on all of our doors and windows. This means your double glazed windows, including the locks and hinges, are protected from manufacturer damage, weather and corrosion damage and any other faults, so you can enjoy peace of mind.

What are the benefits of double glazed windows?

Double glazing has a number of benefits over single glazing. It is an ideal choice to improve your home’s energy efficiency, as the layer of insulation between the secondary glazing panels ensures maximum heat retention inside your home and minimum heat loss from the outside pane. This also reduces the noise pollution that enters your home.

In addition to noise insulation and saving on your energy bills, the double glazing cost could be a wise investment, as it may increase your property value.

What causes condensation in double glazing?

Condensation can sometimes occur between double glazing panels. This is caused by the sealant around the double glazed glass failing and allowing the warm air from inside your home to enter the air gap between panes. Condensation will then form as the surface temperature of the double glazed window is cooler than the room. If you see this, it is time to replace or upgrade your old windows.

At Safestyle, our windows are manufactured to the highest standards to stop any condensation, leaks or draught between the glass panes. Contact us today to get a quote on your replacement windows.

Is triple glazing better than double glazing?

Much of the energy saving benefit is made in the jump from single glazed windows to A-rated double glazing. Whilst there are incremental savings to be made from double glazing to triple glazing, it is often in our experience not offset by the additional cost of triple glazed windows.

Our recommendation to our customers is that double glazing strikes the best balance between cost and the benefits of excellent thermal insulation, noise reduction and a positive energy rating. We would only recommend triple glazing for a few cases such as living close to a very busy road where there are advantages to their sound reduction.
