Planning glass for the light in Marlow
In Marlow the shortest day has roughly 7 h 49 min of daylight and the longest about 16 h 39 min. The noon sun sits near 15° above the horizon in winter and 62° in summer — so glass that faces south collects useful warmth from October to March, while a west-facing door may need solar control to stop it overheating in July.
How it works in Marlow
Every job in the SL7 district follows the same steps: price online, survey, written quote, made-to-measure manufacture and fitting, 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.

Can you widen my opening in Marlow?
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.
Which sliding door suits a home in Marlow?
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 Marlow is the place to settle it.
