It can be used on the interior or exterior, transports undesirable moisture out of window joints and is full-surface adhesive. The new joint adhesive tape from pro clima – CONTEGA SOLIDO IQ – will make the installation of windows easier and will provide protection against damage to structures. When installed on the inside, it is vapour-retarding and airtight; when used on the outside, it is resistant to driving rain, open to diffusion and windtight.
European Technical Assessment confirms high durability even under demanding conditions, as well as compatibility with DIN 68000-2
Long-term durability, even subject to extreme heat or cold: pro clima’s INTELLO and INTELLO PLUS airtight membranes are humidity-variable and very resilient. This has now been confirmed by independent technical testing by the German Institute for Construction Technology (DIBt).
“Our humidity-variable INTELLO and INTELLO PLUS vapour retarders, together with our DB+ product, were the first humidity-variable vapour retarders to receive national technical approval from the German Institute for Construction Technology (DIBt). These products have now been awarded approval in the European Technical Assessment (ETA). As a result, they now also have the required proof of durability demanded by DIN 68000-2 for vapour retarders with humidity-variable diffusion resistance,”

Advantages of humidity-variable vapour retarders: Maximum reliability for built structures
The INTELLO and AEROSANA VISCONN airtightness systems are Passive House certified
Particularly energy-efficient, permanent adhesion and reliable performance – these are the requirements that pro clima demands of its construction materials. After all, good buildings that provide healthy indoor environments can only be achieved if the quality level of the construction components is right. pro clima has this quality level checked at regular intervals by independent external bodies.
New: the AEROSANA VISCONN sprayable sealant is Passive House certified
The Passive House Institute has now confirmed that the new humidity-variable AEROSANA VISCONN airtightness sealant also fulfils its strict criteria and achieves the highest efficiency class of phA. This spray-on or brush-on airtightness sealant is proving very popular among installation technicians as its saves time and can be used flexibly. Thanks to its humidity-variable sd value, it can be used both indoors and outdoors. It can cover cracks and joints of up to 3 mm in width. If the system fleece is also used, then larger joints can also be dealt with. Once it has dried, AEROSANA VISCONN is permanently elastic and very resilient. It can also be plastered over without any problems.
Planners and architects are including the new AEROSANA VISCONN in their construction projects because they know that spraying or painting on provides reliable sealing for challenging detailed features. In addition, the humidity-variable diffusion resistance also provides better protection for building components. Installation technicians appreciate the ease of installation and the time savings compared to working with adhesive tapes. In this way, a seamless, sealed airtightness layer can be achieved for walls, ceilings and floors in a time-saving manner.
With INTELLO, winter building sites are not a problem
With a hydrosafe value of over 2 m, INTELLO protects insulation structures reliably – even if there is a lot of building moisture present due to plastering and the installation of screed, for example. In addition, pro clima INTELLO is the first humidity-variable vapour retarder with European technical approval. There are a number of humidity-variable vapour retarders – Michael Förster (the head of Application Technology at pro clima) explains the differences between them in this video:
Awkward detail features that are difficult to access, and 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. The sprayable, Passive House-certified 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.
AEROSANA VISCONN: Passive House-certified, sprayable airtightness sealant with a humidity-variable sd value.

This spray-on or brush-on airtightness sealant is proving very popular among installation technicians as its saves time and can be used flexibly.
Just like the popular INTELLO airtight membrane, AEROSANA VISCONN too is humidity-variable. The sprayable sealant reacts to ambient humidity and adapts to the relevant conditions in an optimal manner. In this way, AEROSANA VISCONN and INTELLO can perform two functions: sealing to provide protection against moisture, while being extremely open to diffusion to allow for good drying out. As a result, building components are particularly well protected.
Thanks to its humidity-variable sd value, it can be used both indoors and outdoors. It can cover cracks and joints of up to 3 mm in width.

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.

pro clima presents projects, products and a guiding principle
How does the selection of construction materials and the professional handling of these materials influence the construction of healthy buildings to live in? This is just one of the questions that MOLL pro clima is considering at BAU 2019. The overall issue of healthier buildings is the focus of the trade fair presence of pro clima, the specialist in windtightness and airtightness. At the heart of Stand 200 in Hall B6, we will be presenting our joint projects with the Sentinel Haus Institut – such as the current research project “My Future Office”, which deals with sustainable, healthier office buildings. However, a significant amount of space is also dedicated to both new and tried-and-tested products that pro clima has developed with the issue of healthy living environments very much in the foreground.
Finding out more, discussing technical issues, experiencing new products at BAU 2019: At the pro clima Stand 200 in Hall B6, everything will be focused on windtight and airtight building envelopes and their importance for achieving healthier buildings.
Airtightness sealing has a wide range of significant impacts on buildings. After all, air can flow through the building envelope in an undesired manner if the airtightness sealing is poor. Substances or energy can be transported in this way – this is referred to as convection.
This means that heat leaves the building in an undesired manner during the winter or enters in summertime.
A joint with a width of 1 mm and a length of 1 m in a building structure looks small, but has a major impact. The heat losses increase by a factor of 4.8. In addition, up to 0.8 litres of humidity can enter the building structure in a single day.
Scientific studies have shown that the thermal insulation performance can be reduced to just 20 per cent in the case of strong air flow (i.e. through leaks).
Alongside these heat flows, water that is present in the interior in the form of air humidity can enter into building components through leaks in the airtightness. In winter, the temperature in these building components falls. Condensation liquid can then form, which can lead to subsequent damage such as mould.
Unwelcome odours or harmful substances can also spread – and who wants to be able to smell what the neighbours are cooking?
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
Dried-out products in paint cans and the time-consuming cleaning of brushes are no longer a problem with the new TESCON SPRIMER.
There will generally be dust present anywhere that bonding primer is being applied. Primer liquids and brushes can easily become dirty. TESCON SPRIMER now provides a solution to these problems: this innovative primer is applied directly from a spray can, which means that it stays clean – and you don’t to worry about accidentally knocking over cans of primer or having them dry out either! This spray-on primer is ready to use in an instant, can be applied at precisely the right location thanks to the adjustable nozzle, and has the same application properties that you are familiar with from other pro clima bonding primers.
Application also possible at temperatures below zero Celsius
Simply shake the can forcefully a few times and you’re ready to start applying TESCON SPRIMER, even during frosty conditions. The bonding primer penetrates deep into the application surface and strengthens dusty subsurfaces or subsurfaces with insufficient load-bearing capacity. It is permitted for wood fibre underlay panels and other similarly absorbent subsurfaces to be still somewhat moist when the primer is sprayed on. Work can also be continued on these surfaces – for example, the TESCON VANA all-round adhesive tape or the adhesive sealing tapes for plaster in the CONTEGA family of products can be applied without any waiting time being necessary. However, TESCON SPRIMER must dry fully for it to achieve its final level of strength.
TESCON SPRIMER can be sprayed on at precisely the location where a reliable adhesive bond is to be created.
Focus on health issues
Installation technicians have often enquired to pro clima about a primer that could be applied from a spray can, reports Michael Förster, an Application Technology specialist at this Schwetzingen-based airtightness and windtightness specialist company: “It took a while to create a product to meet this need, as we wanted our new primer to be a lot better in terms of environmental friendliness and occupational health and safety than the spray-on primers that are already available on the market.”
“The advantage of spray-on primers is that they are significantly easier to work with than similar products in bottles. After all, you don’t need a brush and you can apply the product precisely where you need it by spraying it on. No lumps form in the primer either. I am delighted that pro clima is now able to offer TESCON SPRIMER – as I know that a lot of attention has been paid to sustainability and that the propellant is not harmful to my health or the health of my colleagues,” says the master carpenter and construction engineer Alexander Erny from Mannheim. He is also impressed by the ease of use of TESCON SPRIMER. The spray can is handy to carry around and is always on hand when he needs it.
TESCON SPRIMER is available from dealers in cans with volumes of 400 and 750 millilitres. Other new products from pro clima can be found at www.proclima.de

Spraying instead of sticking: AEROSANA VISCON can be used to create a new type of vapour retarder and airtightness seal.
Who says that airtightness films always have to come as sheeting in roll form? With AEROSANA VISCON, there is now a liquid vapour retarder and airtightness layer than can be sprayed directly onto surfaces to be sealed. When it dries out, the acrylic dispersion turns into a durable, seamless elastic protective layer. Suitable subsurfaces include non-plastered masonry, porous panel-form materials and membranes too. With its humidity-variable sd value, AEROSANA VISCON is suitable for interior air sealing and also for protected outdoor areas. The spray film is water-based and has achieved excellent values in the hazardous substance test. Continue reading →
