The Sanford is built on Endurance's 48mm solid engineered-timber core, so it stays rigid in Cornish wind and driving rain rather than flexing like a foam-filled slab. Roughly 25% of the face is glazed across 3 apertures, and every unit is fitted with toughened, argon-filled double glazing as standard. Supplied and installed across Cornwall by our own CERTASS-registered fitters, finished in any of the 20 Endurance colours shown on this page.
The Endurance Sanford is a full-glazed door built around 3 glazed apertures, with 25% of the face glazed across 3 separate apertures. That proportion of glass is deliberate rather than decorative: a run this generous is built for hallways that need genuine daylight, not just a glimpse of the porch. Every unit is toughened and argon-filled as standard, and the 3-aperture layout is what gives the Sanford its particular rhythm on the door face.
On site, the Sanford tends to get chosen for the same reason twice over: it suits bright entrance halls, and the full-glazed layout gives homeowners exactly the balance of light and privacy they were describing before they'd seen a single sample.

Which Cornish properties suit the Sanford
With 25% of the face glazed across 3 apertures, the Sanford sits comfortably on contemporary homes — the glazing is proportioned to lift a hallway without turning the entrance into a shop window. On a reclaimed brick elevation the panel lines read as intentional rather than decorative, which matters on the terraced streets around Truro and St Ives where every door on the row is visible from the pavement. If your hallway is genuinely dark, this is one of the better-lit options in the full-glazed category without stepping up to a full-glass design. Whatever the property type, every Sanford we quote is measured and templated on site rather than to a standard size, so the panel and glazing proportions shown here translate exactly to the finished door.
Getting the colour right on the Sanford
The Sanford's 3-aperture glazing pattern photographs well in Rich Red, where the frame lines around the glass stay crisp rather than disappearing into the panel colour. White Foiled is the other finish we would put in front of a customer choosing this design — it is muted enough that the glazing, not the door colour, is the first thing you notice on the full-glazed face. For a bolder frontage, Claystone gives the same proportions a completely different character without changing the layout at all. Whichever you choose, ask to see a physical sample against your own reclaimed brick; screens flatten differences that are obvious in daylight. Woodgrain finishes such as Golden Oak and Irish Oak are available on the Sanford as well as the flat colours, and tend to suit this panel shape particularly well on older properties.
Getting the glazing and hardware right
We would default the Sanford to an obscure design such as Neo across all 3 apertures if the door opens straight onto a pavement, and offer Harmony as the upgrade where more visibility through the glass is welcome — a rear garden door, for instance, or a porch that already screens the view. On hardware, this panel layout carries a slim lever handle well; a bulkier traditional set can look slightly out of scale against apertures this size. Lead time on the Sanford is the same as the rest of the range — typically four to six weeks from survey to fit, whatever glass and hardware combination you choose.
