Exterior driving rain proof window sealing from renewable raw materials

ISO-CONNECT OUTSIDE „BLUE LINE“ is a bio-based window connection foil for exterior use, the basic component of which is obtained from renewable raw materials. The polymers used to manufacture it are based on sugar-containing plants such as sugar beet, sugarcane, corn, maize and similar species. These types of plant take up large quantities of CO2 while they are growing. This in turn reduces actively harmful greenhouse gases, thus contributing to a balanced climate.

Sustainably produced foils such as ISO-CONNECT OUTSIDE „BLUE LINE“ nevertheless provide the same technical properties as foils based on purely synthetic raw materials. ISO-CONNECT OUTSIDE „BLUE LINE“ is a flexible and stretchable special foil for connection joints on windows, doors and panels to create a seal that is both air tight and impermeable to driving rain. The soft and very adaptable window connection foil has an acrylate self-adhesive strip for quick and effective application to window frames. ISO-CONNECT OUTSIDE „BLUE LINE“ allows vapour diffusion and allows moisture to escape to the outside. This meets the requirements of the Building Energy Act as well as the RAL “installation guide”.

For indoor area please use ISO-CONNECT INSIDE „BLUE LINE“ .

Application Areas

Bio-based exterior weather protection sealing

ISO-CONNECT OUTSIDE „BLUE LINE“ is a component from the „BLUE LINE“ organic product range. It is used as weather protection for bonding over connection joints on the outside structure of buildings.

The adaptable bio-based special foil is very flexible in its application and is characterised through its low inherent rigidity, allowing problem-free application around corners and conforms to different shapes. The material’s high elasticity makes it particularly suitable for the reliable sealing of movement joints.

Due to the extremely high elasticity of the material it is particularly suitable for the reliable sealing of moving joints. Even on extreme movements between elements the flexible window connecting film ensures a high ultimate tensile strength.
