Tilt and slide patio doors in Horsham: what to know
These are the points a surveyor will go through with you when you choose tilt and slide doors for a home in Horsham:
Is the opening in your Horsham home wider than about 3 m? If so, tilt and slide hardware will not carry a sash that size, and a lift and slide door is worth comparing.
If a bedroom in your Horsham home opens onto a balcony or garden, the tilt position on tilt and slide doors lets in fresh air at night without leaving the door open.
- A sliding restrictor, available on many systems, limits how far the sash can open, which is useful for upstairs balconies and homes with young children.
- When closed, the sash is drawn back into the frame and presses onto gaskets on all four edges, giving a window-like seal against draughts and driving rain.
- The tilt position opens a narrow gap at the top of the sash while the hardware holds it in place, so a room can be aired without leaving a door open.
Light and sun in Horsham
Sun angles matter for big glazed doors. Around Horsham, midday sun reaches about 62° in summer and drops to about 15° 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.

From survey to fitted door in Horsham
Here is the usual sequence in Horsham: guide price, free survey, written quote, then manufacture (typically 2–4 weeks for uPVC or 4–6 weeks for aluminium, from survey sign-off). Fitting typically takes 1 day for a straight swap in an existing opening. Nearby, we also survey in Crawley, Cranleigh and Horley.
Do you need approval in Horsham?
English Building Regulations treat a new or replacement external door in an existing home as a controlled fitting: it needs a U-value of 1.4 W/m²K or better (or Doorset Energy Rating band C) if more than 60% of it is glazed (Approved Document L), and safety glass in a critical location (Approved Document K). Compliance is arranged through a competent person scheme installer or a Building Control notification, so you get a certificate for your records.
Choosing the specification
- Sash side. A left or right opening sash, chosen to suit furniture, the patio layout and the way you walk out.
- Colours. White, woodgrain or coloured foils on uPVC; standard or RAL powder coats on aluminium.
- Material. uPVC for a lower price and shorter lead time, or aluminium for slimmer frames and powder-coated colours.
Questions about tilt and slide doors in Horsham
Can you match other doors and windows in my Horsham 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 is a tilt and slide door?
A tilt and slide door is a patio door whose opening sash can either tilt inward at the top for ventilation, or move forward and slide parallel across the fixed panel. The handle selects the mode. When closed, the sash is pulled back into the frame and sealed on all four sides, so it behaves more like a large window than a conventional slider.
How wide can a tilt and slide door be?
A tilt and slide door in our range is typically about 1.5 m to 3 m wide overall, with one opening sash and one fixed panel. The sash size is set by the hardware's weight limit, which is lower than for inline or lift and slide systems. If you need a wider opening, a standard aluminium slider or a lift and slide door is the usual alternative.
Do I need Building Regulations approval for a tilt and slide door?
A tilt and slide door replacing an existing door in England is a controlled fitting, so it must be fitted by an installer registered with a competent person scheme or notified to Building Control, and the glass must be safety glazing to BS EN 12600. Planning permission is not usually needed on a house when the door looks similar. Flats and listed buildings may need consent, and Wales, Scotland and Northern Ireland have their own rules.
