Energy Rated Windows

When you are choosing new windows – you need to know all the facts and that’s especially true when it comes to energy rated windows. How do you know if you are choosing windows that will help you maximise savings on your heating bills?

energy rated windowsThe good news for homeowners is that windows can now be rated for energy efficiency in the same way as white goods, such as fridges.

An easy to understand scheme, run by the BFRC (British Fenestration Rating Council), allows windows to display a rating from A – G, with an ‘A’ rating being the best, after they have been rigorously tested.

All the energy efficient windows installed by Coastline Windows are rated as ‘C’ or above - meaning that they can ALL carry the ‘Energy Saving Recommended’ tag.

The alphabetical rating shows how well our energy rated windows stop heat from passing out of your rooms, how much sunlight they allow to travel inside through the glass to help heat your home at no cost to you, and how little air can leak in or out around the window.

The main reasons why you should choose windows that carry a ‘C’ rating or higher are that:

- They save you money on your heating bills
- They are better for the environment

- The top energy rated windows use the sun’s power to help heat your home. 

Excellent thermal insulation ensures that heat loss through your windows is kept to a minimum. 

Together, these functions result in your heating bills and energy consumption being dramatically reduced. Less energy also means the production of less greenhouses gases – which is better for the environment.

The Glass and Glazing Federation believes that if all replacement windows installed throughout the UK were ‘B ‘and ‘C’ rated, each household could save the energy equivalent of making 34,000 cups of tea.

If you are looking for new double glazing, make sure you are dealing with a company that has a great reputation for providing replacement windows. Sussex-based Coastline Windows can offer you that.

We also provide solar panels if you want to take your home’s energy cost savings to another level and do even more for the environment.

There is no need to compromise on style as you can choose energy rated windows from Coastline Windows in many designs including Casement windows, Sash windows and tilt and turn windows.
