When Should You Replace Your Double Glazing?

Double glazing units tend to have a life span of up to 20 years making them a worth while investment. Around the 15-20 year mark is where you might want to consider looking into double glazing window replacement job. Lots of warranties are on offer as well, depending on your budget, with most warranties being around the 10-year mark. One of the benefits of quality windows is that they are low maintenance as well. During the lifespan of your windows, maintenance tasks should be minimal, leading to a lower cost in the long run. It is worth, cleaning your new windows regularly to keep them looking good and in optimum condition. With a longer lifespan, quality window prices are even more worthwhile over time. It is also worth looking at our repairs page if your windows are not in their best shape but still not requiring a full replacement.

What Are The Benefits of New Windows For Your Home?

Now that we have looked at when to replace your double glazing, it is important to understand how this investment benefits you and your property. As the most cost-effective choice, uPVC windows and their hinges are a worthwhile addition to any living space, helping you to renew your home’s style and save money in the long run as well as reducing noise.

Improved Energy Ratings

The most energy-efficient double glazed windows are awarded the A++ rating, and the least efficient option has a G rating. At the cheaper end of the scale, you will more often find those with lower ratings. This means you won’t be able to save as much on your bills later on. A larger initial double glazing with optional extras makes a better investment in the long run, getting you windows with a higher rating to help more with energy-saving options.

Efficient double glazing such as this makes your home cost less to run, saving you more money on heating bills. Due to this alone, a higher initial price may prove to be a better investment in the long run.

Enhanced Security

In addition to the latest locking mechanisms, modern windows are available with a wide range of glass pane options. For new windows, or to replace existing windows, you may want to consider toughened glass. If your window frame is 800mm or less from the floor, then your glass will need to be toughened, although this will increase your cost. This is manufactured by heating glass to a very high temperature, which is then cooled at a predetermined rate, making it 5 times as strong as ordinary glass to make sure it doesn’t break, and if it does, it breaks into smaller, less harmful, crystalised pieces. Choosing toughened glass panes can increase the price you pay for new double glazing by around 20%. The locking systems, toughened glass and sturdy hinges allow your home to achieve the upmost of modern security. Your windows will also reduce noise in your home.

Range of Colours

Maybe you’re looking for current on-trend shades like Anthracite Grey or Jet Black, or perhaps you want to make a splash with vibrant shades of red and green with your job. This choice can be down to personal preference if you would like to reinvent your home, or you may need a particular authentic finish to suit your existing aesthetic. Whatever the reason, you can expect a higher double glazing price than for a white uPVC frame which will affect your budget.
