Hearth Materials for Gas or Solid Fuel Use

The hearth is a physical barrier to protect the surrounding area on which a fire can be fitted. It is made of a non combustible material to suitable sizes to comply with document J of the Building Regulations.

Our HETAS and Gas Safe installers will advise you on suitable sizes to fit your choice of appliance. There are many materials available to provide an aesthetically pleasing solution to protecting the combustible area around the close proximity of the fire.

Damage to the top surface can be sanded and buffed back to a great finish, and dressed with a slate oil

Easier to scratch than granite, but easier to repair

Marble and Granite

Hard but porous materials, can be honed to reveal the natural beauty of the material or polished to high glossy luxurious look

More difficult to scratch than slate, but also more difficult to repair.


Lighter in colour than sandstone, therefore easily marked, limestone is a porous material and requires sealing before use to prevent soiling.

Usually matt and soft to the touch.  Most popular limestones are Portuguese (linea markings) or Agean limestone (more consistent in colour with small inclusions).

Stone Darker in colour than limestone, riven or smooth.  We offer natural flagged hearth in four colours for a rustic charm suited to stoves and brick fireplaces.  IMAGE OF BUFF HEARTH

Hearth Options

Materials Description Image
Granite granite-hearth
Granite (Gas & Electric)

Made from a single slab of highly polished granite approximately 20mm thick which is placed on 30mm risers.

As standard they are 15” in depth.

Granite (Solid Fuel)

Usually referred to as ‘split and slabbed’ or ‘cut and slabbed’. These hearths are made from highly polished granite sections to allow for expansion and contraction from the heat.

They are filled underneath with a lightweight cement mix which helps dissipate the heat throughout the hearth. Without this heat dissipation the hearth would be put under a great amount of pressure which ultimately causes the hearth to crack.

As standard they are 15” in depth.

Tiled Hearths Tiled hearths are a very traditional form of hearth. They are made from 6” x 6” tiles. As with the granite hearths for solid fuel these hearths are filled underneath with a lightweight cement mix. As standard they are 15” in depth. Black and white checked hearth
Slate and Limestone These hearths are the same as the “Granite for Gas & Electric” use hearths with the standard 15” depth and only suitable for gas or electric. slatelimestone


Materials Description Image
Cast Iron Arch Black Finish A painted matt black finish. Both the traditional and the black finishes are most appropriate for multi fuel applications as polished finishes can tarnish with high temperatures.
Cast Iron Arch Black Highlighted Finish

Highlighted Finish is where certain elements of the casting are polished on a black painted background.

Although suitable for use with multi fuel, highlight finish may tarnish with high temperatures.

Cast Iron Arch Black Full Polished Finish

Full Polished, as the name suggests, where the entire product is polished. Although suitable for use with multi fuel, full polished finish may tarnish with high temperatures.


Tiled back panel A tiled back panel is manufactured as a complete back panel to be fitted prior to installing the fire itself. It will protect the mantel from the heat of the fire and provide a decorative and protective area between the fire and the mantel shelf.
