Why should I upgrade to a double or triple glazing window installation?

You may be noticing that your current glass isn’t helping your home stay warm. In many older homes, single-glazed glass features in windows, doors, and other spaces. These designs are inefficient and are prone to excess heat loss as well as condensation.

Not only does a single glazed pane provide less security as the older panes are generally weaker glass, but older windows and doors often use wooden frames and structures. While they offer some protection, timber can often wear away over time and in bad weather, meaning it loses its strength.

The type of glass you have also affects your conservatory, too. Many older structures use polycarbonate, a cheap plastic-based material, for roofing and surrounding panels. Rather than give you a bright, airy space, it loses heat almost immediately and allows weather from outside to play havoc with the room.

So, if you’re experiencing any of these issues, then investing in new glass for your home could transform it completely. Double glazing and triple glazing can make your home feel more spacious, more secure, and you won’t have to clean it regularly either. With its cutting-edge materials, this glass will perform for a lifetime.


What are the differences between double glazing or triple glazing?

The main difference between double glazing and triple glazing is the amount of glass they use. Double glazing uses two panels, while triple glazing uses three. While the increased number of panes can help triple glazing to offer increased insulation, it means the cost goes up. Not only that, but double glazing has its advantages too.

For example, double glazing is a more flexible option for your home. With less glass, your windows will be more lightweight. There’ll be less cover from natural light, giving you a brighter space. Additionally, double glazing puts less weight on uPVC and aluminium frames, meaning you could get smoother, more reliable operation for longer.

However, triple glazing offers better energy-saving benefits. It puts more in between your home and the outside world, giving you increased protection from the cold. With a warmer space, you can also save more money on your central heating. That way, you can start to get money back on your investment straight away.

Triple glazing also makes your home even safer than double glazing. Most triple glazing installations only use toughened glass panels in their designs, meaning your windows and doors can give you stunning security with triple glazing.

For these added benefits, triple glazing does come at a premium though. On average, triple glazing costs 30% more to install than double glazing. Not only that, but installation is more complex and can take longer, disrupting your home. Therefore, it’s essential to consider what matters most to you before making a decision.


How does double glazing and triple glazing make windows better?

Windows are a crucial element in how you heat and provide light for your home. 

In a new casement window, double glazing works with the frames to shield your space from the cold. These advanced windows give you outstanding insulation without any reductions in natural light, thanks to slim uPVC and aluminium. Both double and triple glazing glass can withstand even the worst weather, meaning they won’t wear down.

You could also add windows to your home that have bold, innovative designs. For example, sliding sash windows use advanced glass in their elegant, upward-opening system. All you have to do is slide the glass up to reveal stunning views and fresh air. When you close the window, you’ll also get superb protection and security too.

In tilt and turn windows, you can tilt the glass any which way to make a window fit in even the smallest room. Not only that, but cleaning becomes straightforward with this design.

Another benefit of adding doors with double glazing is that you can convert your home into a bright, natural space. You can invest in sliding and bi-fold doors that use multiple large panels of glass to give you incredible light, views and energy-saving benefits. They sit on an in-line slider, so they provide a seamless gateway to your garden and preserve space inside your home too.
