About Sash and Case Windows
By bringing together uPVC sliding sash frames, double glazing, and sprung counterbalance sashes, our windows are worlds away from their previous version, where iron and lead sash weights sat upon a waxed cord, creating the perfect storm for breaking, sticking, and costly maintenance work.
Separated by glazing bars, with at least one movable panel, our uPVC sash and case windows offer all the architectural features associated with traditional sash windows, from brass ironmongery and external sash horns to internal rings or hooks, with results that speak for themselves.

Double Glazing
Paving the way towards cosy, noise-free homes, our double-glazing services are designed to propel home comfort levels. Driving energy efficiency, reducing condensation levels, and creating a barricade against cold drafts, our double-glazing installers will place two ultra-robust glass panes together, divided by a layer of argon gas.
Triple Glazing
As the driving force behind toasty homes, reduced noise pollution, and wallet-friendly energy bills, adding an extra pane of glass can make all the difference. Our triple glazing option takes heat retention a step further, trapping in warmth to help you get the most out of your radiators. When energy costs are going through the roof, don’t let your heat escape through your windows.

Aluminium
Creating an appearance that you have to look at twice, our aluminium windows are renowned for offering the best of both – an exclusive, contemporary look with all the benefits of slim frames. Flooding your rooms with light, offering vast views of your surroundings, and steering clear of the outdated bulky look, build a frame design that works for you, from our menu of glazing options to our unparalleled colour selection.
Obscure Glass
Ensuring you can enjoy all the benefits of natural light, without compromising on your privacy, our window installation service is focused on reducing glass transparency, while preserving your home interiors. Get in touch to find out about our broad range of patterns, designs, and opacities.
Toughened Glass
At five times stronger than traditional glass, Toughended glass, also known as TSG, is renowned for its ultra-safe shattering process. Designed to split into small fragments in the event of a break, our window fitters in Glasgow and Edinburgh strive for maximum strength, minimal risk. Whether you’re installing toughened glass to meet building regulations or seeking a safety net for high footfall areas, this service is centred on equal parts safety and architectural excellence.
Laminated Glass
Taking the gold for its unwavering strength, laminated glass is unmatched in its insulation and shock resistance properties. Meticulously manufactured to meet rigorous safety standards, our laminated glass is designed to remain in place when smashed, benefiting from a centre layer of polyvinyl butyral to avoid hazardous shards.
Georgian Bars
Creating a charming, cottage feel, Georgian bars give the illusion of smaller panes of glass, slotting seamlessly into traditional homes. While Georgian bars are often placed between glazing layers for optimal convenience, the panel can be positioned externally, adding character to your property.
Mechanical Joints
Recognised as a superior alternative to welded joints, mechanical joints are renowned as a visually striking feature, incorporating traditional charm into home exteriors. Combining specialist woodwork with next-generation installation techniques, our window fitters in Edinburgh and Glasgow are painstakingly trained to meet ever-evolving energy-efficiency, security, and noise-reduction demands, while preserving the art of mechanical joints.
Mitre Joints
Ideal for homeowners chasing a fresh and contemporary appearance with its diagonal joint structure. Introducing mitre joints to sash windows offers the advantage of clean lines, superior performance, and extreme strength.
Colours
Creating windows in a vast range of colours, from on-trend White and ultra-sleek Anthracite Grey to fostering a quaint, cosy feel with Chartwell Green, we believe that durability and aesthetics can walk hand-in-hand.
Hardware
Transforming run-of-the-mill windows into statement features, our hardware represents the ultimate conversation starter. From solid chrome sash pulls to gold sash eyes, we combine expert-led uPVC window installation with a keen eye for design, exuding a sense of timelessness.

uPVC Sash and Case Windows FAQs
No they will not. While timber sash and case windows require regular upkeep to combat jamming, uPVC alternatives are meticulously designed to operate smoothly over their lifespan, avoiding costly replacements and inconvenient sticking.
Absolutely! Whether you’re seeking a set of windows in keeping with your home’s period features or you’re simply keen to avoid drastic changes, we take pride in injecting our designs with your most intricate needs, preferences, and goals.
Overflowing with benefits, uPVC’s appeal extends far beyond its low-maintenance nature, unwavering convenience, and accessible price tag. Renowned for its versatility, uPVC windows are designed to slot into any home, from timeless period properties to modern head-turners. With the ability to replicate the appearance of original timber sash, without the associated upkeep, costs, and lack of durability, uPVC has quickly become the obvious choice for décor-loving homeowners.
Balancing style and practicality, sash windows incorporate world-class mechanisms, supporting enhanced ventilation, fool-proof safety features, and easy cleaning methods. Each of the two frames – known as sashes – operate using a spring balance system, allowing them to slide up and down. The top and bottom sash can also tilt inwards for cleaning purposes.
Exuding a sense of timelessness, Georgian sash windows are regarded as one of the oldest window styles available, adding a touch of ageless sophistication to classic properties. Featuring a design known as ‘six over six,’ where six small panes of glass sit upon each of the two frames, Georgian windows are designed to appear authentic, mimicking the appearance of genuine timber.
Combining a distinctly low-maintenance nature with all the benefits of high-performance windows, this option is undoubtedly a homeowner’s favourite. Symmetrical, timeless, and visually appealing, with a quintessentially British feel, each sash has the ability to slide vertically over the other, paving the way for enhanced ventilation.
We are vetted by respected external organisations, including FENSA and VEKA Independent Network, helping to ensure that we consistently maintain high standards of service and workmanship.
