Airtight building connections

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


Air tightness 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 is essential in achieving your passive or low energy project. ReynaConnect duofoil 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.
