What Are Sash Windows?

Sash windows are traditional windows made of one or more movable panels, or “sashes,” that form a frame to hold panes of glass. They are designed to slide vertically or horizontally within the window frame to open and close.

Sash windows are a popular choice, known for their classic and elegant appearance, commonly found in older or period-style homes. They provide good ventilation and can be a stylish addition to both traditional and modern architectural designs.

Frequently Asked Questions About Mock Sash Windows

Flush and sliding sash windows are both similar window styles but are in fact different. Flush windows are made from a single sash where the window does not come out further than the window frame and sit ‘flush’ against the property, and can be opened inwards or outwards. Sliding sash windows are made from two sash windows which are stacked vertically and can be opened by sliding them up or down.

Traditionally, a sash window is made up of two sashes which slide up and down vertically to open and close. The sashes are the frame of the window which hold glass, which is usually double glazing nowadays. They slide up and down, using a pulley and weight mechanism hidden in the sash window frame. When you open a sash window, the weight counterbalances with a weight inside the window frame. Read more about ‘what are sash windows?‘ in our in-depth guide.

Casement windows open on a hinge outwards, whereas a sash window slides up or down on a sliding mechanism. Casement windows and sash windows are the most popular window styles, they both provide a very different style to the overall look of your home. Sash windows are ideal for period homes and conservation areas for a timeless feel. Casement windows provide a modern aesthetic and add visual appeal to homes of any style or age.

The average cost of a sash window installation depends on a number of factors such as the material, style, structure, and number of windows. Sash windows add value to any home by increasing the market value, and provide a beautiful aesthetic feature so it’s certainly worth the extra cost. Phair Windows & Glass provide a free no-hassle quote, and from the initial design visit to installation, we can take care of it all.

Professional, skilled, great communication from the on-site team - honestly, the best workmen I’ve ever had. They left the place tidy and neat. Thanks guys! They did a great job on a dreary, winter’s day with a smile. I love the new porch, which was a decent price. Honestly though, the sales guy Tom and the crew of Cal, Jake and Aaron were great. After having had a bad experience before with a different company, I’ll be using Phair Windows to replace my windows in the near future as well.

Absolutely amazing job from everyone. Getting the quote from Tom was very easy, fast, very clear and informative and good price. The process was very easy and adjustable to my hours. I got fitted a bathroom and a bedroom window and the guys were very friendly, professional, hard worker and i was very impressed with how clean they were. They brought their own vacuum cleaner, did the job, and when they left it looked like they weren't even there. Absolutely recommend, and will be back again for more windows.

After experiencing an absolute nightmare with a claim put in to Aviva insurance, I found Phair Windows and Tom. As I live in Kent and my elderly parents in Leicester Tom had to navigate all of us. From the very beginning I told him a price and a vision. He delivered exactly what my parents wanted, in exactly the time frame he had given and bang on budget, even with slight changes from mum along the way. The workmen had total respect for my elderly parents and the disruption was a minimum. Thank you Tom and all your chap's who delivered a first class porch at a reasonable cost.

Phair windows & Glass fitted us some new French doors. They were prompt, friendly, and respectful of our property. Tom gave us the best price, cheaper than other companies. There was no messing about. We gave a deposit and they came on the date they said. We will use them again in the future. They have done a lovely job.

The initial visit from Tom gave a good impression of the company - a friendly clear, up-front quote for the work needed. We appreciated this straightforward, honest approach. The follow up visit with the surveyor was arranged easily and again was straightforward. The fitting was conducted by Jason, Angus, Jake and Arron. Professional, friendly, and hardworking- a credit to any company. They worked hard throughout the day, and we were able to just leave them to get on with the job. They ensured we were happy before they left and in addition left everything clean and tidy removing all the waste. Our conservatory looks fantastic, and the materials used are of a high quality. Would highly recommend. Reasonable price too. Thank you!
