The May 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 42% 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 Endurance May is a full-glazed door built around 3 glazed apertures, with 42% of the face glazed across 3 separate apertures. That proportion of glass is deliberate rather than decorative: a run this generous is built for hallways that need genuine daylight, not just a glimpse of the porch. Every unit is toughened and argon-filled as standard, and the 3-aperture layout is what gives the May its particular rhythm on the door face.
We recommend the May most often for statement entrances, where the full-glazed proportions do more of the visual work than an elaborate glass design would.

Statement entrances
This is a full 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 May to your property type
At 42% glazed, the May is neither a bright, glass-dominant design nor a fully private one — it occupies the middle ground that suits architect-led projects. We would point a customer with a dark, narrow hall in Looe 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 May 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 May's panel layout
The May's 3-aperture glazing pattern photographs well in Anthracite Grey, where the frame lines around the glass stay crisp rather than disappearing into the panel colour. Pearl Grey 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 full-glazed face. For a bolder frontage, White Foiled 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. Woodgrain finishes such as Golden Oak and Irish Oak are available on the May as well as the flat colours, and tend to suit this panel shape particularly well on older properties.
Getting the glazing and hardware right
In the May'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. Florida 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 Looe. 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 May.
