The Mixen 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 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 Mixen is one of the half-glazed designs in the Endurance single-door library, with 9% 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 Mixen its particular rhythm on the door face.
On site, the Mixen 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.

Which Cornish properties suit the Mixen
The 3-aperture layout on the Mixen was clearly drawn for a specific kind of hallway: one that needs a defined amount of daylight rather than either none or all of it. That makes it a strong fit for dark hallways, and we fit it regularly on streets in St Ives where the original Victorian doors would have carried a similar glazed proportion before they were replaced with plain uPVC decades ago. Against slate it holds its own without needing a bold colour to do the work. Whatever the property type, every Mixen 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.
Which of the 21 Endurance colours suit the Mixen
The Mixen's 3-aperture glazing pattern photographs well in White Foiled, where the frame lines around the glass stay crisp rather than disappearing into the panel colour. French Navy 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, Rosewood 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. Dual-colour finishing — a different shade inside and out — is available on the Mixen at no extra cost, which is worth considering if the hallway decor doesn't match the exterior palette you want.
Finishing touches on the Mixen
In the Mixen's apertures, obscure glass such as Florida keeps the hallway private while still passing daylight, and is what we fit as standard unless a customer asks otherwise. Diamond 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 3-aperture rhythm on a more contemporary elevation, while pewter or black points it towards period streets in St Ives. Lead time on the Mixen 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.
