Highest quality for airtightness – Components with Passive House certification make planning and installation easier

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.

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.

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:

New: the AEROSANA VISCONN sprayable sealant is Passive House certified

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.

BAU 2019: At Stand 200 in Hall B6, the focus is on healthier buildings

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.

Why do I need airtightness sealing at all?

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.

Fuge in der Luftdichtung

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?

Reliable planning and implementation of window joints

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

The design principle – The joint is what counts!

A new type of airtightness seal: spray-on or brush-on liquid film from pro clima

This innovative product impresses with its wide range of possible applications

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

Why do adhesives stick?

Adhesive tapes: how do they work, what should they be able to do, and what can they do?

Carpenter uses adhesive tape to seal a building

Considerable lengths of various adhesive tapes are used when sealing buildings.
A carpenter can be seen here sticking the interior corners of a window when working on the interior of a fire station.

Adhesive tapes are used as bonding aids in a wide range of applications in the creation of airtight building envelopes. Several hundred metres of tape are often used on a single building! Adhesive tapes have become established as bonding agents for these applications (just as nails are the standard solution for timber structures). They have to fulfil their functions for a number of decades to ensure that the building in question fulfils the standards expected by the energy consultant and by the building client. This article provides an overview of adhesive technology and the key properties of adhesive tapes typically used in construction. Continue reading
