Whether it's tight schedules, rising cost pressures, or a shortage of skilled workers, as a window manufacturer or installer, you face major challenges on the construction site every day. Nowadays, speed, ease of installation, and functional reliability are more important than ever.
This is precisely why we developed ISO-BLOCO HYBRATEC – equipped with pioneering HYFI-TECH. This innovative hybrid technology with integrated foil firewall combines the advantages of modern multifunctional tapes and classic foil sealing in a single product. The result: four unbeatable advantages – for window installation that seals four times better. With significantly reduced installation time, absolute airtightness, outstanding protection against driving rain, and exceptional expansion capacity, you create tangible added value for your company and your customers.
Discover here how ISO-BLOCO HYBRATEC with FACTOR4 makes your everyday installation work more efficient, safer, easier, and therefore more economical.






Here is our installation time comparison, which shows the
differences between two methods of window sealing.
– The innovative solution with ISO-BLOCO HYBRATEC multifunctional tape
– The classic version with window connection foils + PU foam
Thanks to HYFI-TECH, the intelligent hybrid technology from ISO-BLOCO HYBRATEC, more windows can be installed in less time. The time saved thanks to faster sealing can be invested directly in additional construction projects – a real productivity booster for installation companies. At the same time, the profitability of each individual job improves, as more work is done for the same fixed costs. This means more profit with the same installation team.
FACTOR4 – Your new productivity formula for window installation:
Fewer work steps, easy application, enormous time savings
*Based on a video-documented installation time comparison, in which window sealing with ISO-BLOCO HYBRATEC was carried out in direct comparison with window connection foils in combination with PU foam. The complete video comparing installation times can be found at www.iso-chemie.de/hybratec-factor4. The actual time savings may vary depending on structural conditions and workmanship.

ISO-BLOCO HYBRATEC is certified by the Passive House Institute as a passive house component. It therefore meets the demanding energy quality standards for use in highly energy-efficient passive house construction. Here, a high level of airtightness in a building is of central importance in order to keep heating requirements very low. The absolute airtightness of ISO-BLOCO HYBRATEC can save a lot of heating energy – an important contribution to the energy transition!

*Compared to the maximum permissible a-value of 0,1 [h · m · (daPa)2/3] according to the requirements of DIN 18542 for the joint permeability coefficient, the a-value of 0.00 for ISO-BLOCO HYBRATEC is at least 4 times better. The latest technical information can be found here.


With over 1.200 Pa, ISO-BLOCO HYBRATEC offers a much higher level of resistance to driving rain than conventional multifunctional tapes and far exceeds the requirements of DIN 18542. Even in extreme weather conditions, this high-performance product provides reliable protection for the connection joint and keeps the building envelope tight and dry.
*With a driving rain resistance of over 1,200 Pa, ISO-BLOCO HYBRATEC has a driving rain resistance that is four times higher than the minimum requirement of 300 Pa specified in DIN 18542 (MF2). The latest technical information can be found here.


In contrast to many single-layer multifunctional tapes with a limited application range of only 5–10 mm, ISO-BLOCO HYBRATEC reliably seals joints from 6–40 mm – with just one tape dimension. This reduces sources of error when selecting dimensions, simplifies logistics on the construction site by reducing the need to change materials, and ensures greater installation reliability – especially in changing installation situations.
Single-layer multifunctional tapes often only have a range of application of 5 – 10 mm, where as ISO-BLOCO HYBRATEC seals joints from 6 – 40 mm with just one tape dimension.
*Based on the maximum joint application range, starting from the minimum joint application range of the dimensions of ISO-BLOCO HYBRATEC. The latest technical information can be found here.
HYFI-TECH IS THE START OF THE FUTURE OF BUILDING ENVELOPES!
With HYFI-TECH, ISO-Chemie presents a smart hybrid technology that integrates foil firewalls directly into the sealing tape. The pioneering HYFI technology combines the high air and driving rain tightness of foil technology with the reliable flexibility and movement absorption capacity of high-quality PUR soft foam.
The result: high-performance, intelligent, and future-oriented sealing products for safe, durable, and energy-efficient building sealing.

ISO-BLOCO HYBRATEC has been awarded recognized environmental certificates – for tested healthy living, transparent life cycle assessment, and sustainable construction projects.

Multifunctional tapes and pre-compressed joint sealing tapes from ISO-Chemie are completely PFAS-free – and not just since today!
As a manufacturer of energy-efficient and sustainable sealing solutions, we have been relying on environmentally friendly formulations for years and consistently refrain from using per- and polyfluoroalkyl substances (PFAS).
For you, this means: safe processing, maximum structural performance, and an active contribution to health and environmental protection – all without any additional effort.
