The round ventilation tube is perfectly suited for applications in unfinished concrete or for installation situations with sufficient installation height.
The flat ventilation tube by FRÄNKISCHE INDUSTRIAL PIPES is perfectly suited for applications in the insulation layer below the screed in unfinished concrete ceilings. Therefore, grouting is no longer necessary in the structural work phase. The flat ventilation tube can thus be installed at the same time as the sanitary and heating system.
The flat tunnel channel is also ideally suitable for remodel or retrofit installation.
Both types of tube are made of polyethylene, are emission- and odor-free, and contain no toxic materials.
