Suitable hearths for wood burners
1. The hearth must be cut and rejoined for solid fuel and stoves. The joints on the hearth allow the heat to disperse without cracking the hearth. The back of the hearth should also be filled with cement on site (some people call this ‘Slabbing’). Bedding the hearth with sand and cement (at the back) will increase its resistance to heat and extreme temperatures by creating a heat soak. It is possible to purchase a hearth or back panel (section where fire is recessed) which has already been filled with sand & cement during the manufacturing process; however this makes it extremely heavy and unpractical to handle
