Slim aluminium sliding patio doors opening onto a garden
Doors for gardens and extensions

Patio doors chosen for the opening and the way you live

Compare sliding, bifold, French and lift-slide systems by views, ventilation, furniture layout, thresholds and the practical movement through the room.

Sliding, bifold and French doorsThreshold and drainage planningLarge-opening survey support
Start with the brief

The widest opening is not automatically the best layout

Panel size, frame position, opening direction and furniture can matter more than the nominal width. The best door should improve views and movement without making the room harder to use.

Sliding doors preserve floor space and can reduce visible framing. Bifolds create a larger clear opening but need a stacking zone. French doors suit smaller openings and traditional elevations, while lift-slide systems can help with larger panels.

The structural opening, exposure, drainage, floor build-up and access route should be reviewed before selecting the final configuration.

Compare patio doors beyond the open position

Most of the year the doors are closed, so views, ventilation and daily access deserve equal attention.

Details that protect the result

Move from a broad choice to a buildable specification

The final recommendation should explain the details that affect survey, manufacture, installation and daily use.

01

Plan the everyday opening

A traffic door or convenient sliding panel often matters more than the full summer opening.

  • Identify the route used every day
  • Check handles and panel direction
  • Keep furniture clear of operating zones
02

Coordinate threshold and drainage

Flush-looking transitions need careful integration with weathering, external levels and internal floors.

  • Review site exposure and drainage
  • Coordinate finished floor levels
  • Understand the difference between low and weathered thresholds
03

Survey access and installation

Large frames and glass need a realistic route from delivery vehicle to opening.

  • Measure gates, stairs and side access
  • Plan lifting and glass handling
  • Protect floors, patios and landscaping
From idea to installation

A clearer route through the project

Each stage narrows uncertainty before the products are manufactured.

  1. 01

    Share the property and priorities

    Send photographs, plans or rough sizes and explain what should improve.

  2. 02

    Compare suitable systems

    Review material, operation, glass, finish and practical trade-offs.

  3. 03

    Survey and confirm details

    Measure the openings and resolve access, interfaces and installation.

  4. 04

    Approve a written quotation

    Confirm the scope before manufacture, installation and aftercare.

Common questions

Useful answers before the first conversation

These are starting points. The property and measured specification still determine the final recommendation.

Are sliding doors better than bifold doors?

Neither is universally better. Sliding doors usually prioritise glass area and views when closed. Bifolds usually prioritise a wider clear opening. The room layout, opening size and daily access pattern should decide.

Can patio doors have a level threshold?

A low or flush-looking transition may be possible, but weather exposure, drainage, structure and finished floor levels must be coordinated. The most visually minimal detail is not suitable in every location.

How many panels should a sliding door have?

That depends on opening width, desired access, glass limits and sightline preference. Two, three and four-panel arrangements can behave very differently, so elevations should be reviewed before ordering.

Do large patio doors overheat rooms?

Large glazed areas can increase solar gain. Orientation, glass specification, shading, ventilation and room use should be considered together, especially on south- and west-facing elevations.

Can old doors be replaced without changing the opening?

Often yes, subject to survey. The existing structure, cill, floor levels, drainage and surrounding finishes need checking before a replacement system is selected.
