How much glass does the Mardale actually let in?

Roughly 0% of the door face is glazed across 1 separate aperture. That is a modest amount, enough to soften a dark hallway without losing much privacy.

Can I choose a different glass design for the Mardale's apertures?

Yes. Harmony and Clarity are the two we most often fit in this layout, but the Mardale's apertures accept the full Endurance glass range, from fully obscure privacy glass through to clear or bevelled options if the door doesn't face the street.

Does the Mardale suit a north-facing or naturally dark hallway?

It will help, though for a genuinely dark north-facing hallway you may get more benefit from one of our higher-glazed designs; this layout is better suited where light is a nice-to-have rather than the main problem.

Endurance Mardale composite door

The Mardale 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 0% of the face is glazed across 1 aperture, 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.

Among Endurance's part-glazed doors, the Mardale earns its place, with 0% of the face glazed across 1 separate aperture. That proportion of glass is deliberate rather than decorative: a small run of apertures like this lets light reach a hallway without turning the door into a window. Every unit is toughened and argon-filled as standard, and the 1-aperture layout is what gives the Mardale its particular rhythm on the door face.

We recommend the Mardale most often for terraced homes, where the part-glazed proportions do more of the visual work than an elaborate glass design would.

Subtle period detail

This is a part glazed design. Anthracite Grey delivers architectural impact and reads sharp against brickwork, render, granite and slate across Cornwall.

Fitted by our own CERTASS-registered installers right across Cornwall — Truro, Falmouth, Newquay, Penzance, St Austell, Bodmin, Camborne, Redruth and every village between.

Matching the Mardale to your property type

With 0% of the face glazed across 1 aperture, the Mardale sits comfortably on village cottages — the glazing is proportioned to lift a hallway without turning the entrance into a shop window. On a pale render elevation the panel lines read as intentional rather than decorative, which matters on the terraced streets around Mousehole and Newquay 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 part-glazed category without stepping up to a full-glass design. We would always recommend seeing the Mardale against a working sample of your chosen colour before ordering, since the panel's proportions change how a colour reads compared with a plainer design.

Colours that flatter the Mardale's panel layout

The Mardale's 1-aperture glazing pattern photographs well in White, where the frame lines around the glass stay crisp rather than disappearing into the panel colour. Schwarz Braun Black 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 part-glazed face. For a bolder frontage, Anthracite Grey 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 pale render; screens flatten differences that are obvious in daylight. Dual-colour finishing — a different shade inside and out — is available on the Mardale at no extra cost, which is worth considering if the hallway decor doesn't match the exterior palette you want.

Getting the glazing and hardware right

We would default the Mardale to an obscure design such as Harmony across all 1 apertures if the door opens straight onto a pavement, and offer Clarity 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. Multi-point locking and a 3-star anti-snap cylinder are fitted as standard regardless of glass or colour choice, so the security specification doesn't change whichever route you take with the Mardale.
