Efficient and environmentally friendly: THERMAX® combustion chamber linings
Fireplaces provide a healthy warmth with clean and economical combustion, with the help of THERMAX® stove refractories. Efficient combustion technology combined with selected stove materials results in a considerable difference between high-quality and standard fireplaces.
A high combustion temperature is achieved with environmentally friendly combustion technology. The higher it is, the more efficient and cleaner the combustion. In other words: less wood is needed for the same heat output. It creates almost no soot particles, which could deposit on the glass, meaning that less frequent cleaning is required.

Extremely resistant to temperature change, less likelihood of breaking:
THERMAX® boards and moulded parts possess a special layer structure; the individual components of a board are interlocked with each other. Tensions caused by temperature changes can be well compensated by THERMAX® boards, making them less susceptible to breakages.

Extremely flexible:
THERMAX® boards are very easy to work with. Trimming is not required for different fireplaces, as the boards can be cut or shaped with simple wood processing tools. Trimming is reduced to standard boards, which can be trimmed on demand for the stoves needing lining. If you require new combustion chamber linings for your end customers, we can provide a quick and straightforward service.
