Airseal: the solution for energy saving & efficient building

Airtight building involves sealing all unintended gaps and seams in a building to prevent uncontrolled airflow. This keeps cold outside air from entering heated spaces and prevents valuable warm air from escaping.

Our complete Airseal system offers building owners, contractors, and architects the ideal solution for constructing buildings that align with the principles of energy-efficient and passive house standards.

What is airtight building?

An airtight building is one that minimizes air leakage, ensuring that outside air does not infiltrate the interior spaces uncontrollably. This concept is crucial in energy-efficient building design, as it helps to maintain stable indoor temperatures, reduce heating and cooling costs, and improve overall comfort.

Bostik’s Airseal system tackles three primary challenges: air tightness, thermal insulation, and protection agains driving rain. When these aspects work together seamlessly, they provide an additional advantage: enhanced sound insulation.

Air tightness

To effectively prevent and control airflow between indoor and outdoor spaces.

Thermal Insulation

To enhance a building’s energy efficiency also mitigating condensation within the building envelope. Achieving this requires the thermal insulation value of the joint to be at least equivalent to that of the surrounding building structure.

Driving Rain Tightness

To prevent water load entering the construction. A watertight barrier on the building exterior is created to that allow moisture to escape while preventing water from entering.

Sound Insulation

Ultimately, when these three aspects work together seamlessly, an additional benefit is achieved: exceptional sound insulation, which further enhances indoor comfort.
