Saving Energy Through Window Replacements – Topic Overview


The fact is that windows provide our houses with warmth, light, ventilation and also play a significant role in enhancing beauty. However, they can also negatively impact home’s energy efficiency. Well, the good news is that now you can reduce energy costs by installing energy-efficient windows in your home. Therefore, if your budget is tight, and you are looking for ways to reduce energy cost, then you should consider window replacements.

Benefits Of Energy Efficient Windows
• Ability to save energy
• Few carbon footprints
• Keeps your home comfortable – it reduces heat loss through windows, which means few cold spots and drafts
• Offer quiet and peace – apart from saving energy; these windows insulate homes against external noise
• They reduce condensation – energy glazing reduces condensation build-up on the inside part of the window

NOTE: the fact is that the cost of installing energy glazing will differ depending on your home and the windows. Keep in mind that window size, installer you choose and the material does affect cost. A double glazing should last for 20 years or more.

In order to get a better idea of how much you can save by replacing windows, you should consider using the saving calculator.

How Energy-Efficient Glazing Works

Energy efficient glazing have two sheets of glasses with a gap in-between, and it is about 16 mm. This creates an insulating barrier that is aimed at keeping heat in. It is important to bear in mind that others are filled with gas. Going for a triple glazed window (having three sheets of glasses) does not mean they are better. By looking at the BFRC rating, you can know the best energy efficient window replacements.

The good news is that energy efficient windows come in a range of frame materials and styles. Performance varies depending on the following:
• Its ability to prevent heat from passing through
• The amount of light traveling through the glass
• Its resistance to air leaking in and out around the window

What To Look For
• The Glass

The most energy efficient window is one that has (Low-E) low emissivity glass. A Low-E comes with a transparent metal oxide coating, and they are mainly installed on one of the internal glasses. The work of this metal oxide layer is to allow light and sunlight heat to pass in but prevent heat from leaking outside.

• Gap Between The Two Glasses

The window comes with a gap in between the two glasses. The gap has trapped air that works as insulation. However, the most efficient window has gasses in them such as Krypton, Xenon, or Argon.

• Pane Spacers

Pane spacers are gadgets that are set around the inside edges to keep the two glasses panes apart. For the glass to effective, consider going for spacers that contain no or little metal; these spacers are often called ‘warm edge’.

Framing Materials

These windows come with all kinds of framing materials offering different energy rating.

• uPVC – this framing material is durable and can be recycled, which is a benefit.
• Wooden – wood is widely used as the framing material. This is because they offer lower environmental impact. The only limitation is that they need regular maintenance. They are mainly used in conservation areas and mainly where the original window had timber frames.
• Steel or Aluminum – The main benefit is that they are durable and can be recycled.
• Composite – This window frames require an inner wood frame covered with aluminum or plastic. The good thing is that it reduces the need for maintenance and keeps the frame weatherproof.

Energy Rating

There are some energy saving windows manufacturers that prefer to display their product’s energy rating from A to G. These windows are tested to determine the capability of retaining heat. In the UK, this is run by The British Fenestration Rating Council (BFRC).


Any window that comes with an energy rating value will also include the U-value. This is the measure of how quickly heat can pass through the material. Therefore, it is important to note that any material that lets out more heat means it has a higher U-value and Vice Versa.

Even though there are some cases where windows with a higher energy performance rating could have a higher u-value, compared to windows with a better energy efficiency rating. If this happens, then know that there are other aspects to that window such as coating or gap between the glass panes.


The replaced windows are going to be airtight compared to your original frames. What does this mean for you? Well, it simply means reduced ventilation. For this reason, it is advisable to consider window replacements with trickle vents, which will let you, control the flow of air as per your wish.

Now that you have this guide you should be sure to make the best decisions when repairing or replacing your old windows. If you learned any tricks of the trade from your personal experiences, feel free to leave a comment telling us all about it!
