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.

Moisture-variability – what it is and how it works

pro clima clients ask – pro clima engineers answer

Moisture-variable vapour retarder membranes are able to adapt their diffusion resistance to the time of year in an optimal manner. As a result, they are more closed to diffusion in winter and can thus protect building components against moisture penetration. In contrast, they are open to diffusion in summer and thus ensure the best possible conditions for drying to the inside.

Moisture-variable membranes react to the humidity of the surrounding air
The moisture of the surrounding air is around 40% on average in wintertime for a vapour retarder installed on a building component in the case of typical usage of the building as a home. This is relatively dry.
Nonetheless, the diffusion flow is from the warm indoor space, through the building component and towards the outdoor air, which is cold and effectively even drier. A high vapour resistance on the inside of the building component inhibits or stops the movement of moisture that would condense along its route towards the colder outer layers, and in this way the structure is protected against the condensation that would otherwise form.
