uPVC Flush French Doors
Flush French doors offer a beautifully balanced, symmetrical grand entrance where both doors close perfectly level within the outer frame. While traditional timber sets require intense upkeep to protect their alignment from the elements, our high-performance uPVC alternatives provide the exact same timeless, elegant silhouette with virtually zero maintenance.
To guarantee outstanding structural strength and durability, Allwood sources its uPVC door systems from the UK’s premier fabricators. Every double-door set is engineered to modern architectural standards and meticulously installed by our specialist team. This ensures an airtight, highly secure, and elegant transition to your garden or patio that complements character properties and modern extensions alike.


Where Do Flush French Doors Look Best?
Choosing the right placement for your double-door installation is just as critical as selecting the profile itself, as the way a door interacts with light, space, and a building’s facade completely changes a property’s character. Because uPVC flush French doors offer a unique combination of traditional balance and clean, flat sightlines, they possess a rare architectural versatility. Unlike standard patio door systems that feature thick, overlapping lips that sit proud of the wall, the flush profile closes perfectly flat within its outer frame to create a smooth, continuous exterior plane.
These premium systems offer distinct design advantages over other door configurations. Whether your goal is to satisfy strict local planning rules in a designated historic zone or to emulate the high-end, minimalist aesthetic of architectural aluminium on a new extension, positioning these symmetrical double doors in the right location is the key to maximising both your home’s kerb appeal and its long-term financial value.
- Country Cottages & Barns: Replicates traditional 19th-century timber craftsmanship when configured with mechanical joints and woodgrain foils, blending seamlessly with rustic stone or brickwork.
- Conservation Areas: Heavily favoured by local planning officers due to their traditional opening mechanism and perfectly flat, symmetrical profile, making them ideal for securing quick approvals.
- Contemporary Extensions: Delivers a sharp, modern geometric look when finished in smooth matt foils like Anthracite Grey or Matt Black, closely emulating high-end architectural aluminium.
- Symmetrical Facades: Eliminates permanent glass overlaps by opening fully from the centre, maintaining a beautifully balanced, uniform look across the back of the property.

Built to Keep Your Home Safe, Warm, and Quiet
While these doors look beautiful and sit completely flat, they are also built to do a serious job. We get all our door systems from the top manufacturers in the UK, and the Allwood team fits them with absolute precision. This means your new double doors will act as a strong, tough barrier that protects your home from bad weather, loud noises, and break-ins. Older double doors often had a reputation for being draughty or easy to force open, but modern engineering has changed all that. By putting strong steel inside the frames and using the best modern locks and seals, these doors fix those old problems completely. They keep your home safe, warm, and peaceful while meeting all strict UK building rules, making your house a more comfortable place to live.
- Top-Level Security: Uses strong multi-point locks and anti-snap locks that grip tightly into steel-reinforced frames, leaving no easy gaps for thieves to prise open.
- Excellent Warmth: Built with clever pockets inside the frames and gas-filled glass to trap heat indoors, stop cold spots, and help lower your heating bills.
- Peace and Quiet: Uses thick glass and tight rubber seals that squeeze together when shut, blocking out noisy traffic and street sounds.
- Weather Protection: Features double seals around the edges to stop wind and rain from getting in, which gets rid of draughts and helps stop dampness.
French Doors vs. Bi-Folds vs. Sliding Doors
When you want to connect your house to your garden, you have three main choices: French doors, bi-fold doors, or sliding doors. Each style works differently, so it helps to compare them before you buy.
Here is how flush uPVC French doors stack up against the other options:
Flush French Doors
Our flush French doors open outwards on simple hinges, just like a standard double door. Because they sit completely flat when closed, they give your house a beautiful, classic look. They match old cottages and modern extensions perfectly. They are very reliable, keep the heat in brilliantly, and are usually the most budget-friendly choice. They are perfect for standard-sized door openings.
Bi-Fold Doors
Bi-fold doors are made of several glass panels that fold up like an accordion and slide right to the edge of the wall. They are fantastic if you have a huge wall and want to open it up completely to the garden. However, because they have a lot of moving parts and tracks, they cost more and need more looking after to keep them sliding smoothly.
Sliding Patio Doors
Sliding doors are made of big panes of glass that slide behind each other on a track. They do not need any space to swing open, which is great if your patio is very small. The downside is that you can never open the space completely because one half of the glass will always stay in the way. They also have thicker frames that do not sit flat like flush French doors.

Frequently Asked Questions
Standard sliding doors and uPVC French doors are priced similarly, but French doors usually offer better overall value. Sliding configurations require large panes of toughened glass and complex track mechanisms, which can raise costs. Premium uPVC flush French doors fit standard structural spaces perfectly, providing a cost-effective way to achieve a high-end architectural look.
Yes. Upgrading to modern, highly secure double doors instantly boosts your property’s energy rating and market appeal. Because our premium uPVC flush French doors close completely flat within the frame, they beautifully replicate traditional timber joinery, which significantly improves your home’s kerb appeal and structural value.
The best French doors combine top-tier British manufacturing with precision local installation. Allwood partners exclusively with premier UK fabricators to ensure every double-door set features advanced multi-chambered insulating profiles, heavy-duty internal steel reinforcement, double perimeter weather gaskets, and high-security multi-point locking systems.
For very wide walls, modern bi-folding doors are the best alternative, folding up tightly to clear away a huge opening to your garden. If you have a smaller patio layout where swinging doors would hit outdoor furniture, a sliding patio door is ideal because it moves entirely within its own track, requiring zero floor space.
Yes, perfectly. They are a great choice if you want to replace old sliding doors or worn-out PVC doors. Because these doors open wide right from the middle, swapping your old doors for new flush french doors makes it much easier to walk out into your garden. It also instantly makes your house look neat and classic.
