Fireplace chamber finishes: brick, porcelain, stone or paintable?
Brick brings warmth and texture and suits period rooms; porcelain gives clean, jointless panels that wipe down; natural stone sits between them with real geology; and paintable Glasroc disappears into your wall colour so the stove does the talking. All four are heat-safe when built properly, so the choice is character, not safety.

Brick: the classic, in 27 colours
Brick slips laid inside the chamber give the fireplace warmth, texture and a sense that it has always been there. We carry 27 colours, from soft creams through buffs to deep clarets, laid straight or herringbone, and where possible we match the brick your house was built from, which is the detail that makes a chamber read as original.
Upkeep is honest: brick shrugs off heat and age gracefully, darkening a little around a hard-working stove in a way most owners like. It suits period terraces, farmhouses and anywhere the room leans traditional.
Porcelain: the clean modern panel
Large-format porcelain panels line the chamber with almost no joints: crisp, contemporary and the easiest of the four to keep, a wipe brings it back to new. It pairs beautifully with black glass cassette stoves and modern freestanding designs, and it is the finish we reach for in renovated interiors where brick would feel like a costume.
The material handles heat comfortably on the right backer boards and adhesives, which is build quality rather than luck; getting that substrate right is most of the job.
Stone: weight and geology
Natural stone brings what neither brick nor porcelain can: real geological character, no two pieces alike. It suits inglenooks, farmhouses and rooms with existing stone, and it takes heat with total indifference. Cost varies with the stone and the cutting, so it is quoted to the design.
Pair it with a stone or oak beam and a flagstone-style hearth and the fireplace becomes the oldest-looking thing in the house, in the best way.
Glasroc: the quiet one
Paintable Glasroc Firecase is a fireproof board finish that simply takes your wall colour, so the chamber recedes and the stove becomes the whole show. It is the most affordable route, the easiest to change your mind about (repaint it), and the right answer more often than its modesty suggests, especially around sculptural stoves that deserve a plain backdrop.
One build note that applies to all four finishes: everything in a chamber lives close to real heat, so the boards, adhesives and materials must all be heat-rated. Ordinary plasterboard in a chamber is the most common fault we are asked to rescue.
Common questions
Which chamber finish is cheapest?
Paintable Glasroc is usually the most affordable, then brick, with porcelain and natural stone quoted to the design. The honest advice is to choose the character first: the price differences are modest against the life of the fireplace.
Can you match brick slips to my original brickwork?
Often, yes: with 27 colours to draw on we can usually get close enough that the chamber reads as original to the house. We bring samples to the survey and hold them against your walls in your own light.
Is porcelain safe next to a wood burning stove?
Yes, built properly: the panels sit on heat-rated backer boards with the right adhesives, which is the part of the job you cannot see and the part that matters. That substrate discipline applies to every chamber finish we build.
Can I change a chamber finish later?
Glasroc repaints in an afternoon; the others are rebuilds, which is why we push the samples-at-home decision hard before building. Choose slowly once, enjoy it for decades.
Do different finishes need different hearths?
The hearth is specified by the stove and Building Regulations rather than the chamber finish, but we design them together so the materials converse: brick with granite or slate, porcelain with porcelain, stone with stone.
