Daylight in Horsham and what it means for your glass
At the latitude of Horsham, the midday sun climbs to about 62° in late June but only about 15° in late December, when daylight lasts around 7 h 54 min against 16 h 33 min in midsummer. A south-facing sliding door lets that low winter sun deep into the room; on a west or south elevation, solar-control glass keeps summer afternoons comfortable.
How it works in Horsham
Start with a guide price online or by phone. A surveyor then measures your opening in Horsham, checks levels and the lintel, and you receive a fixed written quote. After you approve it, the door is made to measure and fitted, with the compliance certificate sent to you.
Approvals in England
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.
Sliding doors in Horsham: questions
Can you widen my opening in Horsham?
Yes. We can form or widen an opening for a larger sliding door, with structural calculations, a steel beam and English approvals arranged. That work is quoted alongside the door.
Who fits the doors in Horsham?
Doors are fitted by installers we appoint and manage under our contract, so your contract and guarantees stay with us. The same surveyed specification goes from the quote to the factory to the fitters.
Which sliding door suits a home in Horsham?
It depends on the opening and budget. uPVC is the lowest-cost option for openings up to about 3.6 m; aluminium gives slimmer frames and wider spans; slimline and lift and slide suit large, high-end openings. The survey in Horsham is the place to settle it.
