A leading provider of home improvements & double glazing in Lincoln
Us and our customers have a rosy glow following a recent string of flush sash window installations, but not everyone is familiar with this design that’s been a staple in the UK since the 16th century. Did you know many historic buildings across the country are fitted with beautiful sash windows, including Buckingham Palace, the official London residence of His Majesty The King?
As the nights draw in and winter looms, there is no better time to be thinking about making your home cosy and welcoming. One way to beat the cold weather is by checking your windows to ensure they have good installation and aren’t giving you the chills. If it’s time for your existing windows to be replaced, why not consider flush sash windows?
Also known as flush casement windows, flush sash windows are designed so the window sash (the movable piece that holds the glass inside the frame) sits completely flush with the face of the frame. This results in a clean, uncluttered appearance, as the sashes don’t protrude out.
It’s difficult to give a ballpark figure for the price of a flush sash window as there are many factors to consider. These include the size of the flush casement window frame (larger windows generally cost more due to the increased quantity of material and labour required for installation) and type of flush sash casement windows you choose. The installation of flush sash windows can also be more complex due to their design, potentially increasing installation costs.
UPVC flush sash windows are the cheapest option, with aluminium and timber typically costing up to 30% and 50% more respectively.
Remember, new windows are required to have a U-Value of 1.6Wm2K or less, with a Window Energy Rating C. This means all new windows are fitted with double glazing as standard. Of course, you could always go one better with triple glazing flush casement windows, but the extra pane is around 30% more expensive.
Aesthetic appeal
The flush finish and traditional charm that flush sash windows offer takes some beating. They also look visually closer to classic window designs. This is because timber windows were traditionally designed with flush fitting sashes, making them a notable feature in many late Edwardian, Georgian, and Victorian properties across the UK.
Bringing perfect balance and harmony to any period property, flush sash windows are also being used more and more in modern developments too.
Save more on energy bills
Modern flush casement windows are renowned for their exceptional energy efficiency. The window sashes close up tightly into the frame, minimising air leakage and improving insulation.
When combined with double or triple glazing glass for an extra layer of insulation, flush sash windows create a formidable barrier against heat transfer, reducing regular reliance on electricity and gas. The way they are made also reduces cold spots indoors during winter.
Improves ventilation
Flush casement windows can open much wider than traditional window styles, ensuring excellent airflow and helping to regulate indoor temperatures. When used properly, they will keep the air in your rooms fresh, and help keep them cooler in hotter weather, so you can start saying hello to a good night’s sleep.
Highly durable
Our flush sash windows are manufactured from durable UPVC (other high-quality materials are available on request — feel free to ask). This means they are robust and built to last, as well as resistant to fading, warping, and other forms of deterioration.
While you can never count on the UK’s unpredictable weather, you can be assured that your new flush sash windows will maintain their appearance and functionality for many years to come.
Enhanced security
Flush casement windows benefit from more advanced, multi-point locking mechanisms than standard casement windows. This secures the window at multiple points across the frame, making it much more difficult for intruders to force the window open. Their flush design of the sash also means no gaps or openings, providing added protection for your family and property.
Reduces outside noise
If noise pollution from traffic or your neighbours is bothering you, flush fit sash windows can make a real difference in helping you discover peace and quiet. Their tight closure helps block outside noise from entering your home, with double or triple glazing options available to further boost sound insulation.
Low maintenance
Our flush sash windows are made from contemporary materials, such as aluminium and UPVC. Unlike their traditional timber counterparts, they only require an occasional wipe down using soap, warm water, and a fresh cloth or sponge to keep them looking their best.
This makes them a great choice if you’re a busy homeowner and want to enjoy your home without sacrificing the extra time associated with timber flush casement windows. On the other hand, timber flush casement windows need regular sanding, varnishing, and repainting to keep weathering, rotting, and pests at bay.
UPVC flush sash windows
Favoured for its durability, minimal maintenance requirements, and superb insulation, UPVC is arguably the most popular frame material in the UK. And remember, you don’t have to opt for standard white - you can easily customise the colour or finish of the frames to appear more like aluminium or wood. Why not consider naturally striking Anthracite Grey flush sash windows to add depth to your property? Or maybe black for a sophisticated edge?
Flush sash aluminium windows
Slim and sleek flush casement aluminium windows are another fantastic option if you’re interested in a modern design aesthetic. Aluminium is a strong and resilient material, which can resist rust and maintain its integrity over time. Like UPVC, it’s also highly recyclable, which is crucial for creating a sustainable home and positively impacting the environment.
Flush sash timber windows
Building purists will argue aluminium and UPVC flush casement windows are most suited to contemporary properties and aesthetics. Instead, they’d rather endorse the timeless beauty and natural qualities of timber flush casement windows.
While being the most expensive material option out of the three, the traditional quality of these windows is elevated through the inclusion of astragal or Georgian glazing bars.
Composite flush casement windows
Versatile for a range of architectural styles, composite flush casement windows combine a timber exterior with a uPVC or aluminium internal cladding. It’s the only way to enjoy the aesthetic qualities of timber, while reinforcing its durability with aluminium or uPVC to maintain its integrity over time.
Unfortunately, composite flush casement windows will set you back considerably more than windows made from just aluminium or timber.
The two key differences between regular casement windows and flush sash windows lay in the design and cost. In terms of energy efficiency and functionality, they operate very much on a level playing field.
Yet, it is the distinct aesthetic of flush casement windows that enhances the visual appeal of a property, making them a popular choice for homeowners seeking to meld modern style with heritage features.
If you’re looking to upgrade your windows and value both form and function in your home design, flush sash casement windows are definitely worth considering.
