Benefits Of The Edwardian Sash Window

Traditional and timeless look

Edwardian sash windows are stylish and desirable. Ace Edwardian sash windows feature glazing bars, which can be obscured by interior curtains. Discover our Edwardian style range of sash windows, that boast of aesthetic charm combined with insulation and beautiful finishing touches.

Allows in plenty of natural light

Natural light is proven to cheer people up and reduce the risk of depression, as well as benefit the general health of your body.

As a striking feature of the exterior, Edwardian sash windows allow more natural light into the home and into the room. The panes are made from one piece of glass, so they are stronger than modern double glazing units, making them excellent thermal insulators.

Expose your home to radiant rays of natural light with our double or triple glazed, crafted Edwardian sash window.

Lets cool air in

Blocking the incoming natural cool air can make a room very stuffy, especially in summer! These windows allow the homeowner to open and close them from either side, allowing a cooling breeze to come in during hot summer nights. This feature keeps the air fresh and prevents you from having to suffer from the dreaded “swamp cooler” effect. This is why they are now really popular with people who want to let in as much fresh air as possible but keep the cold out.


Comfort is a key feature of the Edwardian sash window. Staying warm in the winter and cool in the summer is a cinch with Edwardian sash windows. The sash windows of the Edwardian period not only give you that extra level of draught-proofing, but they provide you with ultimate comfort.

Save money on your bills

You will end up saving yourself money on your bills if you choose to buy our Edwardian double-glazed windows.

As this style is ideal for allowing light in, using double glazing would mean that more light would become trapped. This will naturally heat up your home, lowering the amount of energy you will have to use. So, not only will Edwardian windows look great installed in your home, but they will also prove to be cost-effective as time goes by.

High level of security

Safety is a big factor in home design, and ace Edwardian sash window definitely fits the bill. The majority of our sash Edwardian windows are protected by solid timber frames which provide increased safety from burglary. Unlike other window styles, such as Georgian and Victorian, the sash can be opened inwards towards the interior of the house. This means violent intrusions are far less likely.

Highly durable

They are built to last. They’re made from good old-fashioned hardwood. Many Edwardian sash windows have lasted over a hundred years and, with proper maintenance, you can make yours last even longer, sometimes of up to two centuries.

Ace sash windows offer an Edwardian window that provides strength, weatherproofing, security and remarkable aesthetics. Your Edwardian sash window will be aesthetically pleasing, whilst fully functional and as outdoorsman-friendly as they come. They were built to last for generations!

Thermally efficient

Original Edwardian windows were not good thermally. Back then, all windows were made with single glazing and would offer very little resistance to heat trying to escape the property.

On the flip side, our Edwardian windows come with innovative thermal enhancements. They are fitted with double glazing as standard, which is supported by a multi-chambered profile. You maintain period aesthetics while also getting the heat retention of market-leading uPVC windows

Noise reduction

At ace sash windows, we provide Edwardian sash windows that are a perfect solution for noise reduction. Traditional sash windows or windows with grids can be a problem if you want to reduce any outside sounds that come in. But, our Edwardian sash windows will block and absorb outside noises, making your time inside much more peaceful.


You can easily clean the visible glass panels of your sashes from outside your building using a proprietary cleansing kit, some soapy water and a soft-bristle brush. All you need to do is clean them with a regular detergent such as fairy liquid or use an anti-mould and anti-bacterial product. Be careful not to use any cleaning products that have bleach in them as they will stain the sash.
