What are uPVC Doors?

uPVC stands for unplasticised polyvinyl chloride, a rigid, weather-resistant material used to make window and door frames. It has become the most popular choice for external doors across the UK, and the reasons are practical rather than fashionable. The primary reason it remains popular is its longevity with low maintenance requirements, which matters even more in a coastal county like Cornwall. Modern uPVC doors are designed with insulated frames and weather seals, keeping the elements out while keeping warmth in. Multi-chambered profiles trap air within the frame, reducing heat loss and helping a room stay comfortable year-round. Many homeowners tell us this is the first change they notice: a genuinely warmer feel the moment the new one is fitted.

Our Range of uPVC Doors

We work with established manufacturers, including VEKA Halo and Endurance, to source high-quality glazing products built around reinforced, internally beaded frames and multi-point locking as standard. Our team supplies and installs four main styles, each suited to a different part of the home.

The Benefits of new uPVC Doors

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.

Made-to-Measure Design

Every door we install is made to measure, so it sits precisely in your opening rather than being adapted to fit. It can be customised in various colours and finishes. Whether your home is a traditional Cornish cottage or a modern build near St Austell, there is a finish to suit it. Internally beaded glazing comes standard on our doors, meaning the glass sits and locks from inside the frame rather than from the outside. This makes it far harder to remove the glazing from the outside, adding a genuine layer of security most people never think to ask about. You can browse our full uPVC windows range if you are planning to upgrade your windows and doors together.

Security You Can Rely On

Modern doors feature strong, reinforced frames and advanced multi-point locking systems, and ours are no exception. Many include an 8-point locking system as standard, engaging at multiple points around the frame as soon as it closes. Toughened glass adds a further layer of protection, resisting impact far better than standard glazing. Security is about more than the door itself. Screws and hinges are concealed wherever possible, and every installation is signed off in line with current building regulations, giving you genuine peace of mind rather than just the appearance of it.

Energy Efficiency and Thermal Performance

Our uPVC doors offer superior thermal efficiency with multi-chambered profiles and tight sealing, which matters in a county exposed to wind-driven rain and salt-laden coastal air. They can feature double or triple glazing for improved insulation, depending on your budget and required performance. Reducing heat loss around a door and its frame can make a genuine difference to comfort and energy efficiency across a whole home. A well-fitted, well-sealed uPVC door also helps reduce the draughts that often collect around older, worn frames.

Built to Withstand Cornwall's Weather

uPVC withstands heavy rain and high winds without warping or fading, which is exactly what an entrance on the Cornish coast needs. They’re built to handle the county’s changeable weather without rotting or warping, unlike timber, which needs regular attention to stay weathertight. Durability and low maintenance make them well suited to a coastal climate, from exposed clifftop properties to sheltered inland villages. Our team has installed doors across the county for many years, so we understand how differently one on the coast can age compared with one a few miles inland.

How We Measure, Manufacture and Install Your New Door

Fitting a new door well takes more than turning up with the right size in the van. It’s a process built on careful measuring, precise manufacturing and installation that respects your home throughout. Here’s exactly what happens from your first visit to the final sign-off.

1. Survey and Measure

One of our team members will visit your home to take precise measurements and discuss styles and finishes. There’s no obligation at this stage, just honest advice based on what will actually suit your property.

2. Made-to-Measure Production

Your door is manufactured to those exact measurements, so it fits your opening without gaps or adjustment. This precision is what keeps draughts out and makes sure the locking mechanism sits and operates correctly for years to come.

3. Careful Installation

Our installers fit your door, protecting your property throughout and leaving the area clean. Most installations are completed within a day, so disruption to your home is kept to a minimum.

4. Sign-off and Support

Every installation is signed off in line with building regulations and backed by our 10-year insurance-guaranteed warranty. If you have any questions once the job’s done, our team remains on hand to help.

Frequently asked questions

Please do not hesitate to contact us if you have any questions regarding Origin Double Glazing or the products and services we provide.

Most single-door installations are completed within a day, including removing the old door and making good around the frame. If any brickwork needs attention, or you are ordering several doors at once, we will agree on a realistic timeframe with you before work starts. We will keep your home secure and weathertight throughout the job, even if it runs across a few days.

uPVC doors are made entirely from unplasticised polyvinyl chloride, while composite doors have a solid timber core wrapped in a GRP (glass-reinforced plastic) outer skin. uPVC typically costs less upfront, while composite doors have a more solid feel and a woodgrain texture. Both are secure, energy-efficient and low-maintenance, so the choice often comes down to budget and appearance.

uPVC doors are highly energy-efficient, featuring multi-chambered profiles and advanced weather seals that significantly reduce heat loss. Many of our uPVC doors come with double or triple glazing options, further enhancing insulation and helping to keep your home warm during Cornwall’s cooler months. Compared to traditional timber or composite doors, uPVC doors often provide better thermal performance, which can lead to lower heating bills and a more comfortable living environment year-round.

Yes. We produce them using the same profiles and colour ranges as our uPVC windows, so a new one can match your existing frames precisely. If you are replacing windows and doors together, we can plan the entire project as a single job to keep everything consistent.

French doors can work well even in a modest garden, since they open the living space toward the outdoors without needing much clearance. If space is tight, we may suggest an alternative opening style during your survey, so it works practically as well as it looks.

Yes, every door we fit is made to measure rather than adapted from a standard size. One of our team members measures your opening in person, and manufacturing follows those exact dimensions. This keeps the fit precise and avoids the gaps or draughts that can come with an off-the-shelf size.
