Connection Couples for low-energy and passive buildings
8. 3. 2026
The joint is the space between the window frame and the masonry lining.
For low-energy and passive houses, it is recommended to seal the connection joint as perfectly as possible, following the designed construction details and building physics calculations. In low-energy and passive houses, every detail of fitting and tightness is taken into account. The connection joint in these buildings should achieve similar parameters as the adjacent structures. The key to the success of a good solution and functionality is the perfectly designed details of the product fitting into the building.
Requirements for the function of the connection joint
Preventing leakage into the joint
zero joint air permeability
effective joint ventilation - minimising condensation inside the joint
enabling expansion
thermal and acoustic insulation
Benefits of proper sealing
Energy savings due to the prevention of thermal bridges and almost zero air permeability
Maximum reliability and durability of the joint
Reduction of the noise level penetrating the joint
prevention of moisture penetration and mould growth in the joint
