At Budget Windows, we understand that replacing your windows, as with many large improvements, can be a daunting and confusing process. It’s a large investment so taking your time to consider all factors is vital. We’ve compiled a guide to help answer your double glazing questions and make the process as simple as possible:
Double glazing windows are made up of 2 layers of glass often separated by a layer of gas (such as argon). This layer of gas doesn’t conduct warmth as well as regular air, making it a great insulator. This layer traps warm air preventing it from escaping your home and cold air from entering it.
The 2 primary measures of a window are:
This is a measure of thermal transmittance – how easily heat can pass through a window. In essence, it will tell you how well the window can retain heat. The U value is measured in Watts per square metre per Kelvin (W/m²K) – the lower the value, the better the window can retain the home’s heat.
British Fenestration Rating Council (BFRC) are the independent body that developed the Window Energy Ratings (WER). This impartial rating considers the entire window and is a measure of its thermal performance.
Windows are rated from A+ to E, with A+ being the most efficient. Building regulations require a window to have a WER of C or better.
Double glazed uPVC window units will have a lifespan of around 30 years on average. The cheaper option isn’t always the best, as this lifespan could vary dramatically depending on the quality of the windows and installation.
The main signs that your double glazing could need replacing are:
Even the most effective heating can be rendered useless by draughty windows. Over time, the seal between the window and its frame could break down, allowing draughts to ruin the comfort of the room and home in general.
Even the smallest of chips in the pane of glass could drastically affect the window’s ability to function at an optimal level. Releasing the insulating layer of gas reduces the window’s thermal efficiency and may lead to higher energy bills.
Even if you can’t see any obvious damage, condensation between the layers of glass is a sure sign that the window’s seal, which houses the insulating gas, has failed. Unfortunately, there is no quick fix for this problem and the whole unit will need to be replaced.
Even you’re not considering selling your property, adding to the value of your home is a sound investment. Many estate agents agree that double glazing can add value to a property and make it a more attractive prospect for potential buyers. Research from the Energy Saving Trust has found that upgrading to double glazing could save as much as £120 a year on energy bills.
Triple glazing does have considerable upsides. It’s generally more energy-efficient, offers better security and offers better sound insulation in comparison to double glazing.
However, it does cost around a third more than the double glazed option.
