Airtight building connections

Contemporary aluminum profiles have an excellent thermal performance thanks to the thermal break and the airtightness of the systems. However, these well-insulated systems require a matching building connection to ensure good overall thermal insulation. The combination of high insulating systems with airtight installation reduces energy consumption, ensuring optimal living comfort with a minimum of heating costs.


Airtightness is an absolute requirement for an energy-efficient building. Reynaers fabricators can drastically improve the airtightness of the building connection, using ReynaConnect (link: ReynaConnect) according to strict procedures. Their expertise and knowledge in this field are essential in achieving your passive or low-energy project. ReynaConnect duo foil is applied around the window or door frame. In combination with our special elastic foam and compression tape, it guarantees a superior airtight building connection.
