How to Check Double Glazing Efficiency

15th February 2024 |

Energy Efficiency

Coloured WindowsUtility bills have been on the rise for a while now. Covered extensively in the news and via consumer affairs websites and advice columns, we are constantly being told to check our homes for energy efficiency to save on our bills and make changes to the way we insulate and update our properties to ensure we optimise our energy efficiency.

But what does this mean and how can you do it without spending a fortune? Can you check your own home’s energy efficiency? Can you tell how efficient and insulating your double glazing is?

There are a number of straightforward DIY options when it comes to energy efficiency, like using draught excluders and insulating loft and underfloor spaces. However, the tried and true method of improving your home’s insulation and its thermal rating is by replacing your old windows with modern uPVC or aluminium options that are either triple or double glazed.

Unfortunately, inefficient or ill-fitting windows can account for a third of heat lost from your home. As a result, failing to refurbish old windows can drive up your energy bills in the winter as well as allow damp and condensation into your home, leading to mould and damage to your possessions and possibly impacting your health.

So what is energy efficiency? And how can you tell if your windows are energy efficient?

In this blog post we’ll be talking you through the factors that relate to energy efficiency in your home, how you can check your double glazing energy efficiency and simple changes you can make to reduce your energy bills and make your home more energy efficient.

What Does Energy Efficient Mean?

In the context of a home environment, energy efficiency refers to the process of reducing the amount of energy required to maintain a steady, comfortable temperature. So if a home is energy efficient, this means it uses less energy. Energy efficiencies can come from superior insulation, efficient appliances, reduced energy use in cooking and heating and lighting.

Put simply, improving the energy efficiency rating of a home is the aim of reducing the amount of energy needed within the property. In turn decreasing the gas and electricity required and positively impacting utility bills whilst maintaining a comfortable living environment.

Are There National Standards of Energy Efficiency?

In the UK, the energy efficiency of a window is rated by the British Federation Rating Council, or BFRC, who will assess how well the frames and glazing of a window or door retains heat.

Windows awarded an A on the Window Efficiency Rating (WER) scale are considered the most energy efficiency while G is the lowest.

When additional ‘plus symbols’ follow an A rating, this highlights even greater energy efficiency and therefore better insulation credentials.

At Majestic Designs our range of windows are rated A+14 on the WER scale. That means our windows not only succeed in insulating homes and retaining heat effectively, but are certified as some of the most energy efficient windows available on the market today.

Are My Double-Glazed Windows Energy Efficient?

To find out if your windows are energy efficient, you need to explore whether they are retaining heat and insulating your home effectively and efficiently. First of all, consider the age of your doors and windows. If your home has its original single-glazed timber windows or uPVC windows that are more than 20 years old, it might be time to replace them to cut down your energy bills.

Have a look at the frames and the panes of glass for wear and tear. Windows that are past their best often warp, flex and can even rot in the case of timber frames. Peeling paint, cracks and gaps are a sure sign that your windows are not energy efficient and need replacing.

Other noticeable factors include an increase in your utility bills as well as draughts, cold spots and condensation. If you find yourself reaching to turn up the heating thermostat more than you usually would, it may be a sign of poor insulation.

A greater number of draughts and cold spots, or if you have noticed more condensation than normal, could be signs of inefficient insulation and windows or doors that need replacing or repairing. In addition to the impact on the structural integrity of your home, increased damp can also result in mould and a multitude of serious health issues for you and your family.

New double-glazed windows are not only warmer and more energy efficient they are also safer and offer better home security, giving you comfort and peace of mind.

How To Check Double Glazing Energy Efficiency

There are several ways you can check your home’s windows and doors for potential energy efficiency issues.

First of all checking for obvious gaps, cracks and fissures in glass and frames should be the first thing you do. Cracks in frames are an insulation issue and a serious security risk and you should prioritise getting any windows, doors or conservatory frames and glass panes with cracks fixed or replaced as soon as possible.

The next step will be to check your double glazing for any condensation. Moisture building up between the panes or on the inside of the window can indicate poor performance and a reduction in insulation capabilities. Greater levels of moisture within a home can also lead to damp and mould and associated health risks.

Check your windows and doors for obvious draughts or air leaks or air movement that could imply a broken seal or damaged frame. You could carefully use a lit candle to assess significant air movement near closed windows, but be careful with fabric curtains, blinds and furnishings.

An infrared thermometer is another way to check heat loss by measuring the temperature of your windows on a cooler day.

Can a High Energy Efficiency Rating Benefit My Home?

Here in the UK, we frequently deal with unpredictable weather, from grey, rainy days to intense roof-ripping storms to heat waves.

To insulate against cold, wet weather, high-quality double or triple glazed windows that offer superior insulation and protection are essential.

With more energy efficient doors, windows and appliances your home will naturally achieve a better energy efficiency rating, saving you money in the long run and creating a more comfortable, safer environment to live in.

The better the energy efficiency rating of your secure, multi-point locking uPVC double glazed windows, the better protection your property will have against exterior noise pollution and extremes of heat and cold.

If you believe that your current windows are not as energy efficient as you would like them to be, you might want to consider upgrading to uPVC or aluminium frames with double or triple glazed glass.

The best way to improve the energy efficiency of your home is by replacing your older-style windows, to reduce heat loss and save you money long-term.
