Individual Hearth Tiles Individual Hearth Tiles are available in various finishes and shapes.
A Standard Size Hearth is 54 inch x 15 inch x2 inch thick with or without a kick (a tongue extending back) but all other sizes are available.
Flat back Hearths are for use when the fireplace opening is level or just in front of the brickwork of the chimney.
Kicks or tongues accomodate fireplaces openings that step back behind the wall line of the chimney breast.
A back hearth is an outsized kick for where the chimney breast has been opened up to take a stove of firebasket. They can be attached to the front hearth or be a separate piece depending on the size and shape.
A cut out is required when the fireplace system is fixed in the floor and is forward of the chimney e.g. Baxi Burnall underfloor and similar systems.
Boxed and Lipped
Boxed and lipped is the standard format for slate, limestone and marble hearths. The top of the hearth overhangs by 0.5 inches (1cm) at the front and either side.
Boxed flush slate, limestone and marble hearths have the vertical returns of the hearth are the same size as the top piece (this costs £10 more than the boxed and lipped price).
There are strict regulations governing the size of a fireplace hearth.
Floor Level Gas Fires
With living flame gas fires, the hearth needs to ensure that it is difficult for someone to lay a carpet right up to the fire.
To this end the regulations (bs5871) insist upon either a 50mm (2 inch) raised hearth or fixed fender.
The depth and width of the hearth or fender can vary with each particular
gas fire, but 300mm depth (12 inches) in front of a standard (16 inch)
fire and 750mm width (30 inches) would be a good guide as a minimum.
Solid Fuel Fireplaces
With an open fire it is recommended that the hearth be 18 inches deep. If there is a fixed fender then there is no defined limit.
For firebaskets with an open fire the hearth is recommended to be 18 inches in front of the fire as with all solid fuel fires. If there is a fixed fender then there is no defined limit.
We can supply separate back hearths for use with fire baskets.
Solid Fuel Stove
The hearth should extend 12" in front of any open access to the fire in the stove.
We can supply separate back hearths for use with stoves
Once the regulations are complied with the size and shape of your hearth is down to aesthetics.
If you have exposed floorboards then the hearth should fully cover the constructional hearth to avoid seeing the concrete.
Mantels and Hearths
If your fireplace has a mantel then the hearth size can vary.
The mantel can stand on the hearth or the hearth can sit between the mantel legs or the mantel can have "cut outs".
