Wide fireplace with a cozy bench

Only 5 cm of insulation needed

Active rear ventilation as the key to optimal fire safety

Just 5 cm of insulation is all it takes for optimal fire safety – thanks to the new BRUNNER insulation concept with active rear ventilation for the BKH series. This concept offers fireplace builders a space-saving, standards-compliant solution for modern fireplace design, opening up new possibilities for creative layouts – without compromising on safety.

This is achieved through convection openings that allow built-up heat to be released in a controlled way. The air gap is limited to just 5 cm. The right technology for endless design possibilities 😎
