Layer by layer.
Steel shell
Load-bearing outer shell
The steel shell forms the structural envelope of the furnace. It absorbs all mechanical loads and defines the furnace geometry.
Insulation
Thermal insulation layer
The insulation layer minimises heat loss to the outside and protects the steel shell from overheating. Critical for energy efficiency.
Safety lining
Permanent protective lining
The safety lining serves as a fallback level. If the inner layer wears down, it prevents breakthrough to the steel shell.
Wear lining
Working layer in the fire
The wear lining is in direct contact with the molten material. It is regularly renewed during relinings — the core business of SBS.
Ready for operation.
Four layers, one system — each one critical to the safety and service life of your furnace.

Selected projects.
Zone-Correct Relining of a Biomass Combustion Chamber
Relining of the combustion chamber of a biomass CHP plant with a moving grate: brickwork above the grate, monolithic lining above it, a stepped interlocking transition and secondary-air nozzles restored to the millimetre.
Charging chute lined monolithically – second assignment for a long-standing customer
Follow-up assignment for a long-standing customer: the charging chute was completely relined monolithically – joint-free right into the arch zone.
Precision work on a divider wall
Monolithic lining of a divider wall in the combustion chamber – a narrow, elongated component where every dimensional deviation changes the flow pattern.
Insulation optimisation on a chamber furnace
Retrofitted external insulation on a chamber furnace – less heat loss through the furnace wall, more stable temperature control inside.
Complete relining at an energy provider's waste-to-energy plant
Refractory relining in the waste-to-energy plant of a major energy provider near Nuremberg – brickwork of the combustion chamber within the scheduled overhaul window.
One year without maintenance – and what it cost
An aluminium furnace went a year without maintenance. The result: heavy slag build-up, reduced charge capacity and a repair bill of over 100,000 euros.
Hood lining on an aluminium melting furnace
Complete refractory lining of the furnace hood on an aluminium melting furnace – executed monolithically for dense, dimensionally stable surfaces.

View all projectsOn site across the DACH region.
From our base in Putzbrunn near Munich, we coordinate projects across the DACH region (Germany, Austria, Switzerland). Our installation teams travel with their own equipment — including special tools, measuring instruments and all required materials. This avoids delays caused by missing logistics and lets us start work straight away.
< 24h response time
In an emergency, our teams are on site within 24 hours — whether in Hamburg, Vienna or Zurich. Including weekends and public holidays.
In-house installation teams
No subcontractors, no delays. Our permanently employed specialists know every furnace type and work independently on your site.
DE · AT · CH
One point of contact for the entire DACH region. We coordinate travel, materials and installation — you deal with just one contact.
