French Doors
OVERVIEW
French doors transform how a room looks, feels, and functions by adding generous light, smooth access, and a sense of connection between indoors and out.
At Impact Architectural Systems, we design French doors for homes, workplaces, and hospitality venues, tailoring every detail from frame material and glazing to thresholds and hardware to your brief, budget, and build programme.
What makes French doors a smart upgrade

Two Glazed Leaves
Two glazed panels open from the centre, giving the set its classic French door look.

Wide & Welcoming Passage
The double-leaf design creates a generous opening that makes entrances feel spacious and inviting.

Easy Day-to-Day Movement
This layout improves everyday flow, making movement between spaces smooth and convenient.

Natural Ventilation
When opened, the doors support airflow and help keep interiors comfortable in warmer months.

Clear Sightlines
Even when closed, the glazed leaves maintain open views and visual connection across spaces.

Balanced & Symmetrical
Compared with a single door, the two-leaf arrangement delivers pleasing symmetry and a sense of balance.
Options to suit every space

French patio doors
French patio doors connect kitchens, garden rooms, and lounges to terraces and lawns, giving you a step-out point for breakfast, barbecues, or summer evenings.

Internal french doors
Internal french doors divide open-plan areas into calmer zones while keeping light flowing through the floorplan ideal for homes, offices, meeting rooms, or snug spaces.

French sliding glass doors
Our French sliding glass doors deliver the look and brightness you love with a space-saving glide instead of a swing arc.
Materials: UPVC, Aluminum, or Timber
The right frame material shapes performance, upkeep, and style. We supply all three so you can weigh trade-offs with a clear view.

UPVC French Doors
Robust, low-maintenance, and cost-effective. Multi-chamber profiles help reduce heat loss, while foiled finishes can echo timber grain for period homes.

Aluminum French doors
Slim sightlines, high strength, and crisp modern lines. Thermally broken frames boost efficiency, and powder-coated colours keep their finish for years, even on coastal projects when specified with marine-grade hardware.

Wooden French doors
Warm and timeless, with excellent repairability over their long life. Engineered timber reduces movement, and factory-applied coatings provide durable protection in sun and rain.

Glazing choices and energy comfort
Most customers choose double glazed french doors for everyday comfort and value. We can specify Low-E coatings to reflect heat back into the room, argon gas fill to improve thermal performance, and warm-edge spacers to reduce condensation at the glass perimeter. For busy streets or apartments above lively areas, acoustic laminates improve sound reduction; for strong sun, solar-control glass helps tame summer heat while keeping the space bright.
French door blinds and privacy options
Glazing brings light; sometimes you also want shade or privacy. French door blinds come in two popular formats. Integral blinds sit between the glass panes, staying dust-free and tidy with simple magnetic controls; perfect-fit blinds clip to the sash without drilling, ideal for post-installation upgrades. If you prefer a soft look without fabric, reeded or frosted glass diffuses the view while keeping spaces bright.

Detailing that lifts the whole scheme
Colour and hardware tie your doors into the room. Choose classic white, elegant greys, or any RAL colour in aluminium; pick squared or sculpted beads to lean modern or traditional; match hinges, handles, and letterplates across rooms for a coherent finish. Side lights widen the view; top lights add height and poise. These small design moves add up to a door set that feels intentional.
Our end-to-end process
Building guidance and compliance
We work to current UK thermal and safety principles and can help you navigate practical questions around Document L (energy), Document M (access), and security expectations often associated with Document Q for dwellings. If you’re exploring permissions or permitted development, the Planning Portal is a helpful first stop. For installer competence and homeowner certification, you can learn more at FENSA.
Typical use cases and ideas

Kitchen to garden
Convert a small window and single door into a wider opening with side lights for a brighter family space.

Home office
Use internal French doors with acoustic laminate to split a lounge into two zones without losing daylight.

Refurb and heritage
Choose timber beads and sympathetic glazing bars to echo original joinery while gaining modern performance.

Hospitality
Pair outward-opening sets with drop seals to keep a café front airy by day and snug by night.

Our goal is a neat, durable installation that looks as good from the garden as it does from the sofa, and a door set that still glides sweetly years from now.
