Which uPVC double glazed windows are the best for me? 🤔

We all want the best for our homes. But if we’re thinking about upgrading our windows, what exactly are the “best” double glazed windows for our home, and why? The best of anything will most likely depend heavily on your own personal needs, wants, expectations and inevitably your budget.

One of the most popular reasons to invest in new windows is improved energy efficiency. Replacing old, draughty and rotten windows with new, energy efficient windows can make a huge difference to your home. They look better, cleaner, more up to date, and if you want to, it’s a great way to completely “reinvent” and modernise (or even re-traditionalise!) the entire look of your home.

FENSA HOMEOWNER: The best double glazed windows combine your preferred style with high-performance features that improve your home, without compromising on either aspect. Top benefits include improved security and energy efficiency, reduced maintenance, less condensation issues and impressive sound insulation. Discuss what you want from your new windows with your installer, to ensure your investment offers the levels you need and if these are the best choice for you.

There are many different types of uPVC window, so how do you go about choosing the right type of window for you, your home and your budget?

Window styles and different types of window.

  • Casement uPVC windows in standard and flush fit (Rehau) ££/£££
  • Vertical sliding uPVC sash windows (ECOslide) £££
  • Timber replacement uPVC flush fit windows (Residence) ££££

A top consideration for most homeowners is what style of window they are looking for. Keep to the same look, or go for something different? If you’re looking to replace the original windows in your home, in most instances we would advise you to stay as close as possible to the existing aesthetics, as these tend to work better with the style of your home.

If you’re embarking on a major refurbishment project, this is a great opportunity to give your home a fresh new modern look.

However in some cases, particularly with Victorian and Edwardian homes, a previous window replacement may have resulted in the traditional window being lost to a modern casement that looks completely out of place. Reinstating new modern energy efficient sash windows or traditional style casements will make a significant improvement to your home’s visual aesthetics.
