Gilded Board, 4 mm Flexible Sheet
A gilded board is a metal foil bonded to a 4 mm mineral
sheet. The sheet underneath is the same clay-and-sand board we make for the stone range. Nothing is quarried and nothing
is electroplated.
Better to be plain about the rest. There is no steel under the face. It will not take a weld, it will not dent the
way a car door dents, and it does not ring when you knock it. What it does is put a metal finish on a column or a curved
counter without a fabricator, a frame or a hot-work permit.
The sheet is 1200 × 3000 mm at 4 mm. It bends by hand, cuts with a knife and a straight edge, and
glues to the wall. If the wall is flat, take the 6 mm board instead — 1220 × 2440 mm, rigid, and it
reads as a panel rather than a skin. Both forms carry the same 42 finishes.

Where it goes
Columns and coved corners mostly, because that is the job a metal panel cannot do. A 4 mm sheet goes round a
shaft by hand, without a former, without a seam cover, and without the fabricator who would otherwise be on site for a
week. Reception counters, curved bar fronts, the inside of a bay window, a door reveal that the drawing wanted in brass
and the budget did not.
The joint is the other reason. Two sheets butt tight and the seam disappears. Steel needs a trim there, or a shadow
gap, and both of those are a line you have to look at for the next twenty years.
How it is fixed
Polymer adhesive on a flat, dry, sound substrate, spread with a notched trowel. No frame, no mechanical fixings, no
welding. The wall has to be straight before the sheet goes near it — adhesive will follow a hollow, and a hollow
under a metal face shows in raking light.
On flat runs the 6 mm board takes the same adhesive, but plan for a shadow gap or a trim at the joint instead of
a butt. It is a different drawing, not a different product.
The finishes
Thirty are foils: silver, gold leaf, the tea and vermilion range, the pale pinks. Twelve are aged metals — rust,
verdigris, brass and copper long past its best. Those twelve are what people mean when they ask for a copper wall that
does not look new, and for the gold one that should not either.
Every finish runs on both forms. If the drawing names a finish we do not have, send a physical sample and we will
match against the foil book rather than describe it down the phone.
Outside
Sheltered positions only: under a canopy, inside a recess, up a soffit where the rain never sits. Driving rain and
full sun need a specified system, and we would rather quote that than have the face lift in two years.
Questions
Will it bend round a column?
Yes, by hand. How tight depends on the finish, because the aged foils are stiffer than the plain ones. Send the radius
and the finish and we will say yes or no rather than guess.
Does the gold tarnish?
The foils hold their colour. The twelve aged finishes are meant to move — that is the point of them. If you want
one that stays exactly as supplied, choose from the foil range.
What is the fire rating?
EN 13501-1 A2-s1,d0. Any fire report names the thickness and the build-up it was tested in, so ask for the report for
the build you are actually specifying.
Can it be used in a bathroom?
Yes, with a sealed joint. Not in a shower enclosure, where standing water finds the edge whatever you seal it with. We
supply it for hotel bathrooms and we turn down steam rooms.
What is the difference from the 6 mm board?
The 4 mm bends and butts; the 6 mm stays flat and takes a shadow gap. Same face, same finishes, different
drawing.
