Sliding doors for extensions and garden rooms across the Scottish Borders
A few practical points decide whether sliding doors for extensions suit a particular room and opening:
Self-building in the Scottish Borders or elsewhere in the Scottish Borders? Ask for the sliding doors to be quoted as part of a wider glazing package so the frames, colours and glass match across the house.
When your Scottish Borders extension is going through Building Control, keep the energy information for the doors to hand, as the inspector may ask for it.
- Being involved at drawing stage means the opening is formed to suit the door, rather than the door being compromised to suit an opening built a few centimetres out.
- Setting the finished floor level before the screed goes down allows a low threshold, typically 15–25 mm, or a flush one with a drainage channel outside.
- A check survey once the opening is built means the door is made to the real dimensions, accounting for any small variation in the brickwork or blockwork.

Daylight and glass in the Scottish Borders
Sun angles matter for big glazed doors. Around the Scottish Borders, midday sun reaches about 58° in summer and drops to about 11° in winter. That low winter sun is free heat through south-facing glass; high summer sun is easier to shade with a roof overhang, and solar-control glass helps where there is none.

Approvals in Scotland
In Scotland, an extension needs a building warrant before work starts, and the doors are covered by it; the design must meet the Scottish building standards for energy and safety glazing.
Questions about sliding doors for extensions in the Scottish Borders
Can you match other doors and windows in my Scottish Borders home?
Usually, yes. Most aluminium and uPVC systems come in standard RAL colours and finishes, and we can quote dual colour where the inside and outside need to differ. Bring photos of existing frames to the survey.
What sliding doors suit a garden room?
A garden room usually suits a two-panel or three-panel sliding door sized to the front of the building, with a header strong enough to carry the roof without pressing on the frame. Aluminium systems are a common choice because they are stable and need little maintenance. Glass with good insulation helps if the room will be used all year.
Why does the steel beam matter for sliding doors?
The steel beam above an extension's sliding door matters because every beam bends a little under load, and a large sliding door needs a straight, level head to run freely. If the engineer knows a wide slider will sit under the beam, they can design for low deflection. Too much movement can make panels stiff or bind.
Can you measure from drawings rather than the built opening?
We can quote from drawings, but we manufacture from a check survey of the built opening, because real openings often differ slightly from the plans. Making a large made-to-measure door from drawings alone risks it not fitting. If a programme makes that unavoidable, any arrangement and who carries the risk would be agreed in writing first.
