Under the Metaloterm brand, we offer our customers single-walled, double-walled and concentric exhaust systems. Our single-walled, soot-fire-resistant and high-quality stainless steel systems are ideal for renovations and new buildings.

All products can be quickly assembled using a sleeve system and can be ordered in black, grey or anthracite. Our double-walled systems are also soot fire resistant and reusable. Thanks to an inner and outer jacket made of stainless steel and high-quality thermal insulation, there are no corrosion-causing cold bridges or thermal bridges. Our concentric systems have been tested with many device types in accordance with EN 613. You will also receive boiler connection pieces for each heat generator in black. Here, too, assembly is quick and uncomplicated thanks to our lightweight components.
