Element assembly / Connection to structures

Windows - a word that has become an integral part of everyday life in our industry. Today's modern window systems have to fulfil many tasks and requirements. A critical point here is the correctly executed connection to structures. This is because important aspects such as air impermeability, permanent driving rain impermeability, temperature differences and many more affect it. When installing windows with products from OTTO, all the basic requirements are taken into account.

The OTTO installation system - simply explained

The OTTO installation system gives you all the important information and combination options you need to meet the high demands of window installation. To this end, we adhere to the specifications of the ""Guidelines for planning and executing the installation of windows and front doors for new buildings and renovations"" (publisher: Gütegemeinschaft Fenster, Fassaden und Haustüren e. V., Frankfurt). This guide describes the three most important levels in window installation.

The 3-level model

Our aim is to explain the functional levels simply and to enable you to select the corresponding products with confidence. In this way you will always fulfil the main requirement with our assembly system: ""more vapour diffusion-tight on the inside than on the outside"" for conventional window installation situations.

Internal functional level

The separating plane of the indoor and outdoor climate must be recognisable over the entire surface of the building components and the outer wall and must not be interrupted. The construction must be airtight on the room side. The separation must take place on a level where the temperature and humidity are above the critical values for mould growth.

  • Airtight
  • Sealed to vapour diffusion
  • Can be plastered over

Middle functional level

In this area, the thermal and sound insulation properties in particular must be ensured. The functional area must ""stay dry"" and be separated from the indoor climate.

  • Sound insulation
  • Thermal insulation

Outer functional level

This also includes the weather protection level. It largely prevents rainwater (driving rain) from entering from the outside. Penetrating rainwater must be drained to the outside in a controlled manner. At the same time, moisture must be able to escape from the functional area to the outside.

  • Impervious to driving rain
  • Windproof
  • Open to vapour diffusion

Safe and tested application possibilities

Multifunctional sealing tapes - The system for quick installation

With OTTO multifunctional sealing tapes for RAL installation, you can seal your windows so that they are open to vapour diffusion according to the principle of ""tighter on the inside than on the outside"". It is perfectly suited for use in new buildings, as it provides a quick and secure seal when installing windows and doors.

Window tape Vario - The system for all challenges

OTTO Vario and Vario Duo window tapes form a system that supports you for all challenges. With the self-adjusting properties of OTTO Vario Duo window tape, sealing your connection joints on windows and doors is a breeze.

Sprayable sealants - The system with many possible combinations

Depending on the exterior wall system, there are different connections between the component and the wall. The usual design creates a joint between the outer wall and the frame construction, which must be sealed against moisture. With OTTO's sprayable sealants, you have a system with many possible combinations.
