uPVC Windows
Energy-efficient, secure and low-maintenance uPVC windows, made to measure in a wide choice of styles and finishes.
What Makes a Modern uPVC Window?
A modern uPVC window has three main parts: a multi-chambered uPVC frame, a sealed double-glazed unit, and the locks, hinges and seals that hold it all together. The chambers inside the frame trap air and add rigidity. The sealed unit uses low-E coated glass, a gas-filled cavity and a warm-edge spacer to cut heat loss through the glass. Good weather seals keep out draughts and rain.
uPVC is still the most popular choice for replacement windows because it gives a good balance of performance, choice and price, and it doesn’t need painting. An occasional wipe-down and a drop of oil on the hinges and locks keeps it working well.
Why Choose uPVC Windows?
- Value. Usually the lowest-cost route to new double glazing, compared with flush, sash or aluminium.
- Easy upkeep. No painting or staining. Clean the frames with warm soapy water now and then.
- Colour and woodgrain choice. White, heritage colours and woodgrain finishes.
- Thermal performance. A multi-chambered frame and modern double glazing.
- Security. Multi-point locking and security hinges.
- Flexible configurations. Side-hung, top-hung, fixed and tilt-and-turn openings, combined to suit each opening.
A modern uPVC window suits most homes, from post-war semis to new builds. For a more traditional look, see our flush casement windows and sliding sash windows.

Inside Our uPVC Windows
Our uPVC windows are a versatile choice for most homes, combining proven performance, security and low maintenance with a wide choice of styles and finishes.
Take a look at the hotspots opposite to see the main parts of our uPVC windows. We’ll confirm the exact specification for your windows at survey, and every window comes with a 20-year guarantee.
Hinges
Heavy-duty, engineered hinges support the weight of the sash and give smooth, controlled opening, with anti-crowbar hinge technology to resist the hinge side being levered open.
Locking
Up to 9-point locking, incorporating two high-compression hinge bolts, secures the sash to the frame all the way round. An enhanced security option is available for specifications designed to meet Secured by Design requirements.
Frame construction
Multi-chambered uPVC construction, with 14 chambers across the combined sash and frame. The chambers help reduce heat loss and add rigidity, and the frame is reinforced where the size and style of window need it.
Weather seals
Dual-density weather seals around the sash help reduce draughts, weather ingress and unwanted outside noise.
Glazing
Argon-filled double glazing with an ultra-clear outer pane, a low-E coated inner pane and a warm-edge spacer helps keep the warmth in your rooms. Clear, obscure and decorative glass is available.
Hardware
Locking handles in a choice of styles and finishes, chosen to suit your windows and the look of your home.
Performance & Energy Efficiency
Our uPVC windows combine a multi-chambered frame with argon-filled double glazing, multi-point locking and dual-density weather seals. Compared with old single-glazed or early double-glazed windows, that usually means fewer draughts and less heat lost through the glass.
How much difference you notice depends on what you are replacing and how your home is heated, so we don’t promise specific savings.

uPVC Windows FAQs
What is the difference between uPVC and PVC-U?
There is no difference. uPVC (unplasticised polyvinyl chloride) and PVC-U are two names for the same rigid, unplasticised PVC used for window frames. PVC-U is the term often used in British Standards; uPVC is the more common everyday name.
Are uPVC windows energy efficient?
Yes. Our uPVC windows achieve a BFRC A+ Window Energy Rating and a U-value of 1.3 W/m²K, with a 14-chamber frame and sash and a 28mm argon-filled double-glazed unit. How much difference you notice depends on what you are replacing and how your home is heated, so we don’t promise specific savings.
Can I have double or triple glazing?
Our uPVC windows come with a 28mm argon-filled double-glazed unit as standard, with low-E glass and a warm-edge spacer. Triple glazing is also available, and we have fitted triple-glazed uPVC windows for customers. We can explain the difference in weight, cost and performance for your windows at survey.
How secure are modern uPVC windows?
Our uPVC windows have up to 9-point locking, including two high-compression hinge bolts, heavy-duty hinges with anti-crowbar technology, and key-locking handles. An enhanced security option is available for specifications designed to meet Secured by Design requirements; ask us if you need it. As with any window, security also depends on correct fitting, which our own team carries out.
What colours and woodgrain finishes are available?
As well as white, you can choose from colours and woodgrain finishes including Cream, Light Oak, Irish Oak, Rosewood, Black Brown, Hazy Grey, Anthracite Grey, Chartwell Green and Matt Black. Ask us about dual colour, with a different colour inside and out. We’ll bring samples to your survey.
How long do uPVC windows last, and what maintenance do they need?
Well-made uPVC windows that are fitted properly typically last for many years, and ours come with a 20-year guarantee. They don’t need painting. Clean the frames and glass with warm soapy water, keep drainage slots clear, and occasionally oil the hinges and locks.
Do you remove my old windows?
Yes. Our own fitting team removes your old windows, fits the new ones, makes good around the frames and takes the old windows away.
