How much glass does the Kuppe actually let in?

Roughly 9% of the door face is glazed across 5 separate apertures. That is a modest amount, enough to soften a dark hallway without losing much privacy.

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

Yes. Kensington and Glacier are the two we most often fit in this layout, but the Kuppe'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 Kuppe suit a north-facing or naturally dark hallway?

Very well — the 9% glazed area is specifically enough to make a real difference to a dim hallway without a full-glass design.

Endurance Kuppe composite door

The Kuppe 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 9% of the face is glazed across 5 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.

Kuppe sits in the half-glazed section of the Endurance range, with 9% of the face glazed across 5 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 5-aperture layout is what gives the Kuppe its particular rhythm on the door face.

We recommend the Kuppe most often for semi-detached homes, where the half-glazed proportions do more of the visual work than an elaborate glass design would.

Reading the Kuppe's proportions on a real frontage

With 9% of the face glazed across 5 apertures, the Kuppe sits comfortably on semi-detached 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 Looe and Mousehole 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 half-glazed category without stepping up to a full-glass design. We would always recommend seeing the Kuppe 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.

Which of the 21 Endurance colours suit the Kuppe

The Kuppe's 5-aperture glazing pattern photographs well in Black, where the frame lines around the glass stay crisp rather than disappearing into the panel colour. Rich Red 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, Brilliant Blue 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 Kuppe as well as the flat colours, and tend to suit this panel shape particularly well on older properties.

Glass designs and hardware for the Kuppe

In the Kuppe's apertures, obscure glass such as Kensington keeps the hallway private while still passing daylight, and is what we fit as standard unless a customer asks otherwise. Glacier is the better choice where the door faces a garden or a quiet lane rather than the street, since more of the pattern reads as clear. Hardware-wise, a chrome or satin handle set suits the 5-aperture rhythm on a more contemporary elevation, while pewter or black points it towards period streets in Looe. Our CERTASS-registered fitters install the Kuppe in a single day in almost every case, including full disposal of the old door and frame.
