Can Double Glazing Save You Money On Your Energy Bills?

Energy Savings

Yes, double glazing can save you money on energy bills by helping to insulate your home and reduce heat loss. This can lead to lower energy consumption and costs over time.

Although the advantages that double glazing has for buildings have been widely advertised, it is estimated that around 7% of households in the UK don’t have double glazing.

The main reason for this is that a lot of property owners don’t know the meaning of double glazing or how it can help lower energy bills.

Double glazing has many benefits, including energy efficiency and decreased noise pollution. If you’re looking for an upgrade from your current windows or are in the process of building a new home, double glazing should be at the top of your list.

Double Glazing Can Reduce The Heat Lost Through Windows and Doors.

A non-energy-efficient house can lose up to 25% of the heat generated from the windows and doors.

In the winter, a building with double glazing is warmer because heat can’t escape and drafts are eliminated. In summer, the extra layer of glass on double glazing helps to reduce solar heat radiation (especially when blinds are added).

Double-glazing units can last for up to 25 years, however, keep in mind that this can depend on a number of different factors including the quality of the double-glazing and where the double-glazing is located on the property.

For example, if your windows face north and are constantly exposed to cold conditions or if they face south and get direct sunlight all day.

How Does Double Glazing Work?

In order for insulation to be effective, there should be a minimum of 16mm spacing between the two glass panes. The cavity should also be filled with an inert gas, like argon, which reduces heat transfer. Lastly, non-metallic separators will keep the panes apart from one another.

The combination of the spaced-out panes and the non-metallic separators creates an efficient insulation layer that is extremely effective in reducing heat loss.

What Are The Benefits of Double Glazing?

Double glazing should be installed from the inside, as externally glazed windows can pose a security risk as the glass can be removed from the outside.

By installing double glazing, you will reduce winter condensation, thereby preserving the appearance of your property and saving on window frame maintenance costs every few years.

Not to mention, your home is more energy-efficient and eco-friendly, producing a smaller carbon footprint.

In addition to regulating the temperature in your home, double-glazed windows also provide extra security and noise reduction. Not only will your family be safer, but you’ll also notice a decrease in outdoor sound seeping into your home.

Double Glazing Energy Efficiency Ratings

The energy efficiency of double glazing units is indicated by a letter rating, similar to the one used for fridges, going from A to G. With A+ being the best rating and having excellent thermal efficiency.

In simple terms, what is an energy efficiency rating?

The Overall Thermal Efficiency (OTE) of a window quantifies the energy performance of an entire window, including the frame and glass. The OTE is represented by a letter which has been calculated based on the three factors:

  1. Thermal Efficiency: How well does the window keep heat in?
  2. Air Leakage: How much cold air leaks through cracks around the perimeter of the window.
  3. Solar Gain: What amount of heat from sunlight passes through the window?

So, if you’re looking to save on energy costs and live in a comfortable home environment, replacing your old single-pane windows with double-glazing is a great option. Not only will it save you money in the long run but you’ll also benefit from improved security and reduced noise pollution.

Upfront Costs vs Long Term Investment

Double-glazed windows will reduce the heat loss experienced by your property and thereby reduce your energy bills. However, installing double-glazing will require an upfront investment.

The initial cost can seem expensive but should be considered a long-term investment as it will reduce your monthly and annual energy costs in the future. Additionally, double glazing adds value to your home when it comes time to sell.

When it comes to monetary savings, A-rated double glazing is estimated to save approximately £180 per year in heating costs for a typical detached property. Over 10 years this would amount to approximately £1,800. (Subject to change, especially with the recent energy price hikes).

The amount of energy savings can be calculated by using the Glass & Glazing Federation Energy Saving Calculator.
