What Are uPVC Windows and Why Choose Them?
uPVC stands for unplasticised polyvinyl chloride, a rigid plastic used to make window frames that do not need painting or varnishing. It has become the standard choice for double glazing across Britain, and the double glazing industry has advanced considerably over the past 25 years, with modern uPVC now outperforming much of what was fitted a generation ago. These windows are popular for their energy efficiency and low maintenance, which makes them a practical choice for busy households. Many homeowners come to us wanting to replace draughty, ageing windows with something warmer, quieter and more secure. Others are extending or renovating and need double-glazed windows that suit a new layout. If you are considering replacing windows in a period property, or replacing every opening in your home, we are happy to talk through your options before you decide on anything.
A Range of Styles and Colours to Suit Your Property
Our uPVC windows are available in a wide range of styles and colours to suit properties ranging from traditional cottages to contemporary new builds. They are also available in various profiles and designs, so you are not limited to a single look across your home. We can discuss which style and colour combination suits your property during your initial contact with us, before we prepare any quote. If your project also includes new conservatories, a warm roof or roofline products, we can plan and quote for the whole job together.
5-Star Rated Services and Products

Vertical sliding sash windows move up and down, keeping the look of an original sash and suiting Georgian and Victorian properties.
Flush sash
Flush casement windows sit level with the frame, giving period and character properties a traditional timber look with modern performance.

The Benefits of new uPVC Windows
New uPVC windows bring more than just a fresh look to your home. Here’s what you can expect from a well-specified, professionally fitted set of windows.
Energy Efficiency and A-Rated Windows
Energy efficiency is one of the first things homeowners consider when comparing windows. A-rated windows offer excellent thermal performance, helping to retain warmth, reduce draughts and lower ongoing heating costs. Multi-chamber frames improve insulation by trapping pockets of air within the profile, while quality double glazing provides further protection against heat loss and changing weather. Correct installation is equally important, as even the most energy-efficient double glazed windows need to be properly sealed to deliver their full benefit. For homes requiring greater thermal performance, we also offer triple glazing and can explain the differences in cost, insulation and everyday comfort.
Built to Withstand Cornwall’s Coastal Climate
Cornwall’s weather asks more of replacement windows than many other parts of the UK. Salt-laden air, driving rain and strong coastal winds can place frames, glazing and fittings under constant pressure. High-quality uPVC resists corrosion, rotting and warping, making it particularly well suited to coastal properties. Unlike timber, it does not require regular sanding, painting or treatment to protect it from the elements. When fitted by experienced window fitters, uPVC windows provide dependable weather resistance for homes across Cornwall, from exposed coastal locations to properties further inland. They are designed to remain secure, attractive and easy to operate through changing conditions for many years.
Security You Can Rely On
Modern windows and doors can improve your home’s security while providing greater peace of mind. New windows commonly include multi-point locking systems that secure the frame in several places, making them more resistant to forced entry than older single-point designs. Strong frames, secure glazing and quality hardware all contribute to the overall protection of your property and living space. Security should form part of the specification rather than being treated as an optional extra. If you have concerns about ground-floor rooms, quieter parts of the building or vulnerable older windows, our uPVC window fitting team can explain the available options and recommend a secure design to suit your home.
Low Maintenance, Built to Last
uPVC windows are a popular choice in Cornwall because they offer lasting performance without the regular upkeep associated with timber frames. They do not require repainting or treating and can usually be kept looking their best with occasional cleaning using warm water and a suitable household cleaner. Basic maintenance involves inspecting seals, clearing drainage channels and keeping hinges and locking mechanisms clean and operating smoothly. These simple checks only take a few minutes and help protect the finished installation over time. Properly fitted windows are durable, weather-resistant and designed to provide many years of reliable use. Matching uPVC doors offer the same practical, low-maintenance benefits.
Our Installation Process
Getting new windows fitted can feel like handing over control of your home for a while, and that’s an understandable worry. Here is exactly what happens from the moment you first get in touch to the day your installation is signed off.
1. Initial Contact and Site Visit
One of our team members will visit your property to take accurate measurements and discuss your goals. We’ll talk through the materials, styles and glazing options that suit your home, and answer any questions you have along the way. There’s no pressure to decide anything on the day.
2. Quote and Design
We’ll agree on a clear, itemised quote before any work begins, so you know exactly what you’re paying for. This covers materials, labour and any additional work identified during the site visit, with no hidden extras added later. You’ll have time to consider the quote and ask further questions before committing.
3. Manufacture
Once you’re happy to proceed, your windows are custom-made to the exact measurements taken at your property. We work with trusted manufacturing partners to ensure every unit meets our quality standards before it reaches the site. Lead times vary depending on the products and options you’ve chosen, and we’ll keep you informed throughout the process.
4. Installation
Our FENSA-registered fitters work efficiently to minimise disruption, using dust sheets and floor protection throughout the job. We keep your home weathertight at every stage, so you’re never left exposed to the elements overnight. Most installations are completed within one to two days, depending on the size and scope of the job.
5. Completion and Certification
Once the installation is finished, we’ll walk you through the completed work and make sure you’re happy with every detail. Your installation is then signed off in line with FENSA regulations and Building Regulations. You’ll receive your certification and warranty documentation shortly afterwards, so everything’s on record.

Planning Permission and Conservation Areas
Local planning regulations may restrict window designs in conservation areas, and some properties carry additional restrictions if they are listed. Before you order, it is worth checking whether your property falls within a conservation area or has any relevant planning conditions attached. We have fitted uPVC windows in period and listed properties across Cornwall for many years and can advise on designs likely to be accepted. If you are unsure, mention this when you get in touch, and we will factor it into our advice.
Please do not hesitate to contact us if you have any questions regarding Origin Double Glazing or the products and services we provide.
These windows are popular across Cornwall because they combine energy efficiency, security and low maintenance in one product. They resist rotting, warping, and corrosion in coastal climates, and are available in a range of colours and designs to suit both period and modern properties. Many customers also find that they reduce condensation and outside noise compared with older windows and doors.
The cost of your windows depends on the number of openings, the style you choose, the glazing specification and any additional work needed, such as repairs to surrounding brickwork. If you are also considering replacing your uPVC doors, we can include these within the same quote. Because every property and job is different, we do not publish fixed prices online. The most accurate way to determine your project’s cost and identify opportunities to improve value for money is to request a free quote following a visit to your home.
Well-fitted windows typically last for 20 to 30 years or more, depending on how they are used and maintained.
