Solutions for sealing all windows – Humidity-variable and full-surface adhesive: the new window sealing tape from pro clima

Simple window installation with CONTEGA SOLIDO IQ

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.

Hydrosafe: Maximum protection for building components

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:

  • Hydrosafe: Maximum protection
  • Some Interesting facts about hydrosafe:

    • Humidity-variable vapour retarders are particularly reliable.
    • Hydrosafe: Maximum protection thanks to a large spread in diffusion resistance value
    • Construction sites during winter months: A vapour retarder must
      1. be sufficiently impermeable = Protection against dampness
      2. but also be extremely permeable later = Maximum drying out
    • Hydrosafe value: sd of a vapour retarder for optimal protection for building components during construction period.
    • Hydrosafe => Maximum protection: against dampness + allows for good drying out
    • Better reliability thanks to vapour retarders with a suitable hydrosafe value.

Flank diffusion – what it is and how to prevent it

pro clima clients ask – pro clima engineers answer

Airtightness is good, but it is not everything: there is also the matter of diffusion! When we speak of diffusion in civil engineering, we are referring to the gradual transport of moisture through a building component. This transport is driven by the pressure difference between the interior and exterior. As water molecules always want to move from warm environments into the cold, diffusion normally occurs from the inside to the outside in wintertime. A vapour retarder hinders the transport of these molecules.

Unforeseen: Entry of moisture through adjacent components

For example, if an interior wall penetrates through an insulation layer (the vapour retarder is cleanly attached to the wall on the left and right, i.e. everything is airtight), so-called flank diffusion can occur. The water vapour looks for the path of least resistance – which in this case is the interior wall. In the case of structures that are open to diffusion on the outside, this may represent a manageable risk. However, if the structure is impermeable to diffusion on the outside, moisture problems can soon occur. After all, there is a fundamental problem here. The interior wall has a large surface area, so it absorbs a lot of moisture, but there is only a smaller area available for drying to the inside – i.e. the wall cap.
