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.

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.

Add a little colour.

Choosing a different colour window can give an immediate update to your home’s kerb appeal. After standard white, anthracite grey is our most popular colour. All of our uPVC windows offer an exciting palette of colour choices, including both smooth finishes and woodgrain effect foils (that resemble painted wood) in the following options:

  • Colour/woodgrain effect foil external with smooth white internal.
  • Colour both external and internal.

Feeling Flush? We check out the new Flush casements that are giving wood a run for their money.

Gone are the days when people had to rely on traditional and expensive materials for older, quaint and period properties. Now you don’t have to compromise on appearance if opting for more efficient and modern uPVC solutions. 

One feature that would always stand out on a wooden casement window was that the casements would sit flush to the frame. This would give a neater, more symmetrical look, and until recently, it wasn’t something that a uPVC could emulate. Opening vents on a uPVC window sat proud from the frame, often creating unequal sightlines, and, if you chose dummy sashes to create an equal sightline (ideal for feature leads and Georgians), the vents could often appear bulky looking.

Examples of timber flush (left) and “lipped” casement windows. The “lipped” casement’s opening vent sits proud of the frame. The flush opening casement sits flush within the frame.

Wooden windows would often have a much more pleasing finish than a uPVC window, which at the time, would inevitably look like the smooth white plastic it was. Over years, the clean white finish would often fade, and take on a more grubby looking appearance.

Even the introduction of so-called “woodgrain effect foils” some time ago now, simply looked like a uPVC window pretending to be wood. It didn’t help that these foils were only available in a limited colour range – including the rather tangoed-tones of “golden oak” and the 80s inspired mahogany rosewood, neither of which looked anything like a genuine stained wooden window.

Example of an oriel bay window in the classic orange tones of Golden Oak, with dummy sashes throughout (so that all the leads line up). Does it look like wood? Not really.

uPVC windows may have been maintenance free with better thermal and security properties, but they were no match aesthetically for their wooden counterparts.

The problem was actually quite simple: that a uPVC window is constructed differently to a timber window. And until the construction of a uPVC window could match that of a timber window, it was never going to cut the mustard.

Finally some innovative companies began to push the boundaries in design and manufacture, producing windows and doors that included genuine timber aesthetics with improved woodgrain foils and traditional ironmongery. These windows, now usually marketed as “timber replacement” led the way in revolutionising the window industry. Consequently today we now have products that much more closely resemble the handcrafted qualities of genuine timber windows, but with none of the maintenance issues – the very best of both worlds!
