Insulated air ducts for over 35 years
For over three decades VENTAFLEX air ducts have been successfully installed above- and underground. We have permanently been working on the optimisation of our good products, expanded our supplies system and met many challenges, for example customised special components.
Because of the successful construction projects with VENTAFLEX air ducts for underground installation we have collected valuable information in order to develop an air duct, which is designed to specifically meet the requirements of underground installation.
