As energy bills continue to rise, it’s no surprise that homeowners in Plymouth, and across the country for that matter, are looking for home improvement solutions to combat these rising costs.
One of these solutions has been the rapid rise in popularity of uPVC, a highly customisable plastic that is now the UK’s favourite window and door material.
At DNA Window Solutions, we install uPVC French doors that not only look the part, but also commit to lowering your energy bills, sometimes by up to £160 per year.
In this guide, we’ll explore what French doors are, why they’re so popular, and how our energy-efficient uPVC French doors can benefit your home here in Plymouth, Devon, and Cornwall.
What is a French Door?
French doors date back to 17th-century France – originally designed to let in as much natural light as possible before electric lighting was commonplace. Today, they’re still prized for the same reason. A French door is made up of two doors that open outwards (or inwards, depending on the setup) from the middle, typically fitted with large glass panels that fill the room with light.
The Benefits of uPVC French Doors
So, what makes French doors such a popular choice for homeowners across Plymouth, Devon and Cornwall? Here are four standout reasons to consider upgrading.
-
Create a Seamless Indoor-Outdoor Connection
French doors are perfect for blurring the boundaries between your home and garden. Whether you’re entertaining on the patio, enjoying a morning coffee, or watching the kids play outside, these doors create a wide, open entryway that makes outdoor access effortless.
-
Let the Fresh Air In
Ventilation is a big deal – especially in the warmer months. With their double-door design, French doors allow you to open both sides and enjoy the refreshing South West breeze. It’s a great way to naturally cool your home and improve airflow without relying on fans or air conditioning.
-
Fill Your Space with Natural Light
Thanks to their large glazed panels, French doors allow natural light to blissfully flow into your home – even on gloomier days. That makes your rooms feel bigger, brighter, and more uplifting, which is especially welcome during the darker winter months in Devon and Cornwall.
-
Frame the Views You Love
Got a garden, coast, or countryside view? French doors are a stunning way to make the most of it. Their wide glass panes act like picture frames, giving you uninterrupted views of your outdoor space – all while you stay warm and comfortable inside.
The Importance of Energy Efficiency in Devon and Cornwall
Living in the South West, you’ll know how unpredictable the weather can be. Investing in energy-efficient external doors isn’t just about comfort – it’s about controlling your indoor environment year-round.
Better Thermal Performance
Modern uPVC French doors come with insulated frames, multi-point locking systems, and high-performance glass. These features combine to create a thermal barrier between your home and the outdoors, helping to regulate temperature and reduce heat transfer.
If you’ve got older doors – especially timber or single-glazed – now’s the time to upgrade to modern, efficient uPVC doors designed for year-round performance.
Cut Your Energy Costs
Because our external French doors reduce heat transfer, you’ll rely less on radiators and electric heaters in the winter, and fans/cooling systems in the summer. That means lower energy bills and a more comfortable home in the long run.
Our customers across Plymouth, Devon and Cornwall often tell us they notice the difference straight away – especially in older homes that used to feel chilly or draughty during those long, dark winter months.
What is uPVC and Why Does It Matter?
uPVC stands for unplasticised polyvinyl chloride – a tough, weather-resistant material used across the window and door industry. It’s a popular choice for homeowners because it’s durable, low-maintenance, and great at insulating your home.
Thermally Efficient by Design
Our uPVC French doors are built with multi-chambered profiles that help trap warm air inside your home. When paired with energy-efficient double or triple glazing, this creates a strong thermal barrier that keeps your property warmer in winter and cooler in summer.
That means:
• Lower energy bills
• More comfortable indoor temperatures
• Less heat loss through your doors
• Reduced carbon emissions
And unlike timber, uPVC doesn’t swell, warp, or rot over time – so you can rely on consistent performance no matter what the South West weather throws at you.

Environmental Benefits of uPVC French Doors
As aforementioned, uPVC French doors help reduce energy use by keeping your home well insulated, which lowers carbon emissions.
