# Carbon Rock Board explained: A1 fire rating, finishes and where it fits

Our flagship panel is rated A1 for fire, comes in over a hundred finishes and is sold by the board. Here is what that means in a real room.

Carbon Rock Board is the panel we specify most, and the one trade customers order on its own. It is a rigid composite board with a mineral core and a decorative face, supplied at £232 a board.

## What A1 actually means

A1 is the top classification in the European reaction-to-fire standard: no contribution to fire. That matters in flats, in HMOs, in hotels and in any escape route, and it is the reason the board turns up in commercial specifications where a timber-backed panel would be refused.

It is worth checking the certificate rather than the marketing on any panel you compare it against. A1 and Class 1 are not the same thing.

## The finish range

Marble and stone, wood grain, brushed and mirrored metal, fluted profiles and solid colours, in over a hundred finishes. Because the face is printed and coated rather than veneered, the pattern repeat is controlled and two boards ordered a year apart still match.

For a feature wall, most people mix two: a stone or marble field with a fluted or metal accent inside the niches.

## Where it fits

Living room feature walls, media wall faces, bathroom and kitchen splashbacks with a moisture-resistant specification, reception areas, and lift lobbies. It cuts with a track saw, fixes to a batten or an aluminium frame, and joins with matching trims.

We supply it to homeowners, joiners, designers and trade, by the board, UK-wide.
