Sliding sash windows vs casement windows – Top 7 differences
21 October 2021 |Advice & Guidance
If your window frames and glazing have passed their best in both performance and appearance, have you considered installing another window style? Instead of replacing ‘like-for-like’, it’s worth investigating alternative window styles out there as they could enhance space and light further compared to your existing window style. Even better, they’re sure to increase kerb appeal and could even add more value to your property, depending on the size and design.
With this in mind, it’s time to introduce you to our two most popular window styles and seven top differences that set them apart.
Versatile casement windows
Available with uPVC, aluminium, or wooden effect frames, walk down any street in Kent and you’re sure to spot this popular window style almost immediately. Featuring a hinged side on the left, right, top, or bottom of the window, casement windows typically swing outwards and firmly lock into place on the non-hinged side of the frame.
Sophisticated softwood sliding sash windows
Installed with either uPVC or timber frames, sliding sash windows are a prominent sight in Georgian, Victorian and Edwardian-era properties throughout Maidstone and Kent. Also used to add unique heritage character to new build homes in the South East, sliding sash windows consist of one or two moving panels that slide up and down using modern-day spring balances – instead of the traditional corded arrangement, for ease.
Are casement windows more secure?
When it comes to security, casement windows are often thought as the more secure choice. Compared to old sash windows, modern casement windows are definitely the most secure. However, state-of-the-art vertical sliders (like ours!) feature window locking systems that exceed building regulations; making them just as secure as casement windows.
Are casement windows more energy efficient?
Out of all the window styles, apart from fixed windows that do not open, casement windows are considered the most energy efficient window style as they have seals positioned all around the frame, helping them to fit as tightly against the frame as possible. Again, compared to old, draughty sash windows, modern casement windows keep much more heat and warmth inside. That said, our stylish sliding sashes can achieve some of the best energy ratings possible, offering U-values as low as 0.8 W/m2K and A+ energy ratings.
What are the differences between casement and sliding sash windows?
As we’ve mentioned above, the main difference between these striking window designs is the way they open and operate. Both provide ample swathes of light and ventilation and can be enhanced further with tough comfort glass, 150+ RAL colours and various natural woodgrain options and extras like Georgian bar detailing, but that’s where the similarities end. For ease, we’ve put together a comparison table to highlight the differences and help you decide which style is best for you and your home.
