Airtight sleeves:

The invisible heroes of your building envelope

They are inconspicuous, but play a decisive role in the energy efficiency and comfort of a building. They are used to seal penetrations in the building envelope, such as for windows, doors or pipes, so that they are airtight.

Why are airtight collars so important?

• Energy efficiency: Seamless sealing prevents warm air from escaping in winter and cool air from escaping in summer. This significantly reduces heating and cooling requirements and lowers your energy costs.
• Mold prevention: Moisture that penetrates through leaks can lead to mold growth. You can prevent this by creating moisture barriers.
• Healthy indoor climate: An airtight building envelope ensures a pleasant indoor climate by preventing draughts.
• Noise protection: They help to improve sound insulation by reducing sound transmission through penetrations.
  Protection against pollutants: They prevent the penetration of pollutants from outside and thus contribute to a healthier living environment.

How do airtight collars work?

Airtight sleeves are usually made of elastic materials that adapt to a wide variety of penetrations. They are fitted around the penetration and ensure an airtight connection between the building envelope and the penetration element.

Advantages at a glance

• Simple installation: They are generally easy to install and do not require any special manual skills.
• Versatility: They are suitable for a wide range of penetrations, from cable penetrations to pipe penetrations.
• Durability: High-quality air sealing sleeves are extremely durable and retain their tightness for many years.
• Cost efficiency: The investment in air sealing sleeves is quickly amortized by the energy savings achieved.

Conclusion

They are an indispensable part of modern buildings. They make a significant contribution to energy efficiency, comfort and health. Their ease of use and wide range of benefits make them a worthwhile investment for any builder or renovator.
