The Ketu 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 16% 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.
Cornwall Composite Doors fits the Ketu more often than most of the half-glazed range, with 16% of the face glazed across 3 separate apertures. That proportion of glass is deliberate rather than decorative: a mid-sized run like this balances daylight against privacy. Every unit is toughened and argon-filled as standard, and the 3-aperture layout is what gives the Ketu its particular rhythm on the door face.
On site, the Ketu tends to get chosen for the same reason twice over: it suits dark hallways, and the half-glazed layout gives homeowners exactly the balance of light and privacy they were describing before they'd seen a single sample.

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

Which Cornish properties suit the Ketu
At 16% glazed, the Ketu is neither a bright, glass-dominant design nor a fully private one — it occupies the middle ground that suits semi-detached homes. We would point a customer with a dark, narrow hall in St Ives 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. We would always recommend seeing the Ketu 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 Ketu's panel layout
The Ketu's 3-aperture glazing pattern photographs well in Chartwell Green, where the frame lines around the glass stay crisp rather than disappearing into the panel colour. Sage 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 half-glazed face. For a bolder frontage, Irish Oak 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 granite; screens flatten differences that are obvious in daylight. Dual-colour finishing — a different shade inside and out — is available on the Ketu at no extra cost, which is worth considering if the hallway decor doesn't match the exterior palette you want.
Finishing touches on the Ketu
Clarity is the glass design most customers choose for the Ketu's apertures, since it obscures the view through without darkening the hallway the way a heavily patterned glass can. Diamond is worth considering if the door sits under a porch roof, where privacy is already handled by the structure and a clearer glass lets more light through. Pair either with a handle finish that matches your existing window furniture so the whole frontage reads as one decision rather than several. Our CERTASS-registered fitters install the Ketu in a single day in almost every case, including full disposal of the old door and frame.
