Application area: renovation


Old building material with modern air-conditioning technology

Limited carrying capacity or insufficient space are great challenges when retrofitting existing buildings with modern AC systems systems. In short: Static, space, optics, preservation order requirements and performance play a big role when choosing the ventilation system.


New efficient systems: the combination does it!

When renovating not only the AC systems systems have to be renewed, but also the air ducts. An air-condition-technological system can only prove its performance in successful combination and the energy doesn’t get lost ‘on the way’  - by bad insulation or leakage. The VENTAFLEX system offers the ideal solution due to material (PUR-rigid foam) and supplies (VentaSnap).
