The OWActive mineral climate ceiling is a so far unique room climate system modelled on nature: it combines the advantages of OWA mineral ceilings with the comfort and energy efficiency provided by radiant heat. In addition, the system of mineral tiles and energy rails allows for easy revision as well as easy integration of further technical installation elements. All variants are tested according to DIN EN 14240 and DIN EN 14037. All performance parameters can be found in our test certificates, which we make available in full at any time. Due to the usual deviations in performance, we recommend a uniform evaluation according to VDI 6034.
