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 exactly where ISO-BLOCO HYBRATEC with FAKTOR4 comes in!
Our multifunctional tape equipped with hybrid technology offers 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 expandability, you can create tangible added value for your company and your customers.
Discover on the following pages how ISO-BLOCO HYBRATEC with FAKTOR4 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.
Thanks to the intelligent hybrid technology of ISO-BLOCO HYBRATEC, more windows can be installed in less time. The time saved by faster sealing can be directly invested 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
Less time per window installation means noticeable savings in labor costs as well as significantly higher efficiency and resource conservation on the construction site. Your employees achieve more in less time—in times of increasing skilled labor shortages and tight schedules, these are decisive competitive advantages.
Inside, the 3-layer multifunctional tape is completely airtight, soundproof and heat-insulating in the functional area, and waterproof to over 1200 pa rainproof. All sealing layers can be sealed in accordance with RAL standards using just one product in a single step. This simplifies procurement and storage, saves material, and reduces sources of error during installation. In addition, extra-long lengths mean very little waste is produced.
The time-delayed expansion of ISO-BLOCO HYBRATEC leaves enough room for precise positioning of the windows. This makes window installation quick, stress-free, and reliable—even in tricky installation situations.
*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 actual time savings may vary depending on the structural conditions and the workmanship.
With its multiple foil barrier layers, ISO-BLOCO HYBRATEC makes the entire installation joint completely airtight from the inside out. Uncontrolled convection heat loss or drafts via the window connection joint are no longer an issue. The multi-layer airtight barriers ensure tight installation joints during a blower door test of the entire building – even at pressure levels five times higher. In addition, the airtight joint sealing has a positive effect on the building's energy performance certificate.
Thanks to its absolute airtightness, ISO-BLOCO HYBRATEC contributes significantly to reducing convective heat loss in buildings. Energy-efficient sealing with ISO-BLOCO HYBRATEC supports the sustainability strategy of many building owners and improves the ecological footprint of buildings—an increasingly important decision-making criterion for window sealing in the modern construction sector.
Thanks to its multi-stage hybrid technology, ISO-BLOCO HYBRATEC offers significantly better energy efficiency than conventional sealing products. Multiple integrated foil firewalls ensure that the multifunctional tape is completely airtight, resulting in enormous energy savings and improved building energy efficiency. Multiple airtight layers provide additional security in terms of the requirements of DIN 4108-7 and the Building Energy Act (GEG).
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. In passive house construction, high airtightness of 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.
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.
Rainwater penetration – much more than just a visual problem! Leaky joints cause lasting damage to the building envelope. The integrated foil barrier layers of ISO-BLOCO HYBRATEC effectively block rainwater and keep the connection area at least 4 times drier than many single-layer MF2 multifunctional tapes. This reduces the warranty risk and is a strong selling point for planners and builders who demand durable, maintenance-free solutions.
Classic 3-layer waterproofing systems are highly dependent on flawless installation in order to function properly. A modern multifunctional tape such as ISO-BLOCO HYBRATEC, on the other hand, offers easy handling and a more reliable solution. Compared to conventional sealing with films, paste adhesives, PUR can foams, backfill cords, and sprayable sealants, sources of error can be greatly reduced.
In times of increasingly extreme weather conditions, awareness of structural moisture protection is growing. ISO-BLOCO HYBRATEC not only offers extremely high driving rain resistance of over 1.050 Pa, but also four times better permanent movement absorption capacity compared to sprayable sealants and PU foams, which can fail even with minor component movements. The multifunctional tape can compensate for several centimeters of joint expansion without tearing, thus providing lasting protection against moisture, cracks, and leaks—a real quality and image advantage for window installation companies.
*With a driving rain resistance of 1,200 Pa, ISO-BLOCO HYBRATEC has a 4 times higher driving rain resistance than the minimum requirement of 300 Pa in DIN 18542 (MF2).
Thanks to its extended functional range, ISO-BLOCO HYBRATEC can be used to seal 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, whereas ISO-BLOCO HYBRATEC seals joints from 6 – 40 mm with just one tape dimension.
ISO-BLOCO HYBRATEC offers at least four times greater expansion capacity than conventional multifunctional tapes. This allows it to adapt perfectly to joints of varying widths, uneven joints, and tapered joints—a major advantage on construction sites, where tolerances in execution are often unavoidable. This results in reliable sealing even with high construction tolerances and component movements.
Especially on construction sites with time pressure or limited scope, installers benefit from the strong expansion capacity and flexible adaptation of ISO-BLOCO HYBRATEC. The installation process becomes more robust against installation factors such as slightly crooked joints, misalignments, or unevenness—which minimizes rework and improves the quality of execution. Window installation companies benefit from the universal application possibilities, higher installation reliability, fewer sources of error, and a quality advantage that pays off.
Despite its extremely high expansion capacity, sealing with ISO-BLOCO HYBRATEC does not result in excessive contact pressure against the joint flanks. This is an important positive aspect for the long-term functionality of large, heavy elements, roller shutter boxes, and large ceiling deflections, such as above lift-and-slide doors.
