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 uPVC Sash Windows Leicester
What is the difference between a flush sash window and a sliding sash window?
Flush and sliding sash uPVC windows are similar window styles but differ in design and functionality. Flush sash windows feature a single sash that sits level with the uPVC window frames, creating a clean, smooth appearance that complements modern uPVC windows beautifully. In contrast, box sash windows or sash uPVC windows consist of two moveable sashes stacked vertically, which can be opened by sliding them up or down. These modern uPVC designs meet the latest building regulations and combine modern technology with heritage charm – an ideal choice for both conservatory installations and traditional sash windows.
How do sash windows work?
Traditionally, original sash windows feature two moveable sashes that slide vertically using a pulley and counterweight mechanism hidden inside the frame. Modern upgrades, such as tilt knobs and sash lifts, enhance both safety and functionality, allowing for easier cleaning and improved airflow. Advances in design have led to new sash windows with impressive thermal efficiency, helping homeowners reduce heating costs and lower energy bills, without compromising their classic character.
What is the difference between a casement window and a sash window?
uPVC casement windows open outward on hinges, while sash uPVC windows move vertically within the frame. Both are highly versatile and available in various styles to suit the style of your home. Casements suit modern properties and provide a sleek, practical finish, whereas traditional sash windows remain iconic in period properties and sash windows restoration projects. With colour finishes such as golden oak and rosewood, or authentic wood-effect uPVC windows, each frame offers charm, durability, and longevity.
How much is a sash window?
The price of new sash windows depends on size, width, material, and finish, from modern uPVC to timber alternatives. Despite a slightly higher upfront cost, these windows offer long-term peace of mind through strength and efficiency. Phair Windows’ expert installers handle everything from design to window installation, ensuring compliance with building regulations and exceptional support from the first email inquiry to aftercare.
What are sash windows and why are they popular in Leicester?
Sash windows are admired for their balance of elegance and practicality. They’re a top choice in Leicester due to their ability to preserve heritage architecture while providing high thermal efficiency and modern technology benefits. Whether you live in a modern home or a period building, they remain a stylish, energy‑saving choice that has truly stood the test of time.

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.
