Awkward detail features that are difficult to access, penetrations and transitions between components with lots of corners and edges are frequently encountered on building sites. With these challenges, creating airtightness seals can be a time-consuming task.
Airtightness sealing with the AEROSANA VISCONN system – a real all-rounder: whether you are sealing a large surface area or a complicated joint detail – AEROSANA VISCONN ensures permanent airtightness everywhere!
The sprayable AEROSANA VISCONN airtightness sealant offers installation technicians an alternative that they can use to seal complicated construction details just as quickly and easily as large surfaces. The AEROSANA VISCONN system is so versatile in practice that a majority of airtightness challenges that arise can be reliably solved using this product. The spray film is water-based and has achieved excellent values in hazardous substance testing.
Numerous possible interior and exterior applications
AEROSANA VISCONN is suitable for all surfaces typically found in construction, such as plastered or non-plastered masonry, porous panel-form materials or membranes. It can also be used as a bonding primer on rough or dusty subsurfaces and covers cracks and joints of up to 3 mm width. Joints of up to 20 mm width can be painted over using fibre-reinforced AEROSANA VISCONN FIBRE, an additional product in the system. To create airtight seals for bigger holes such as when sealing penetrations of pipes or ties, a piece of AEROSANA FLEECE can be used that is put in place before being painted or sprayed over.

Joints to other building components are always challenging: they are just a few millimetres in width, but have to offer the same performance as an exterior wall with a thickness of 40 centimetres. Alongside the external influences that act on a building component, there are also laws and standards that stipulate requirements that joints have to fulfil. The wishes of clients or investors are additional considerations that have to be taken into account. The quality and performance of window joints are dependent on good planning, installation according to the three-layer principle, and the choice of materials used.
Careful installation is important in order to ensure the performance of the building envelope and to avoid structural damage and mould. The design principle of three functional layers must be taken into account during planning and installation
Anyone who wants to plan, build or live in a building that is free from damage should choose a vapour retarder with an effective hydrosafe value. Hydrosafe? Yes, it sounds complicated but we’ll explain what it means in simple terms in these new proclima.tv videos:
The airproofing layer protects the insulation from moisture and condensation from the inside, ensures that the insulation works effectively and provides a healthy indoor living environment.
The thermal insulation separates the indoor from the outdoor climate. The temperature difference between the two climates attempts to become equalised through the flow of air. This means in winter the warm air from the building transfers through the structural elements to the outside. The airproofing layer prevents this air flow, the so-called convection, and therefore the loss of hot air to the outside. The interior space is here not hermetically sealed off – like using a plastic bag – from the outside air. Instead, the exchange of air from the inside to the outside continues via diffusion.
