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.
