The Mayon 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 1% 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 Mayon earns its place, with 1% 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 Mayon its particular rhythm on the door face.
What sets the Mayon apart on the doorstep is proportion rather than gimmick — the panel lines and glazing are sized so the door reads correctly from the pavement and not just up close. It has become a regular recommendation for narrow hallways.

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

Where the Mayon looks right
At 1% glazed, the Mayon is neither a bright, glass-dominant design nor a fully private one — it occupies the middle ground that suits privacy with light. We would point a customer with a dark, narrow hall in Redruth towards this design over a solid panel, and towards it over a full-glazed design if they have young children or simply prefer not to be visible from the street when answering the door. As with every Endurance design, the Mayon is backed by the 10-year manufacturer guarantee covering the core, the hardware and the colour finish, regardless of which property type it's fitted to.
Colours that flatter the Mayon's panel layout
The Mayon's 1-aperture glazing pattern photographs well in Brilliant Blue, where the frame lines around the glass stay crisp rather than disappearing into the panel colour. Rosewood 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, Black 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 slate; screens flatten differences that are obvious in daylight. If you're unsure between two finishes, our configurator lets you preview the Mayon in each of the 21 colours before you commit to a survey.
Hardware and glass options for the Mayon
We would default the Mayon to an obscure design such as Vienna 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. Our CERTASS-registered fitters install the Mayon in a single day in almost every case, including full disposal of the old door and frame.
