This innovative hybrid technology combines the high resistance to air and driving rain provided by window connection films with the optimum expansion force and high long-term capacity to absorb movement of pre-compressed PUR soft foam.
“ISO-BLOCO HYBRATEC combines the quality features of premium window connection films with the benefits of high quality BG 1 and BG R-certified multi-functional joint sealing tapes”, explains Inge Knorn, the successful sealing specialist’s Marketing Manager. ISO-BLOCO HYBRATEC stands out from conventional multi-functional joint sealing tapes with its exceptional functional characteristics.
100% reliability in terms of energy efficiency and resistance to air and driving rain
Multiple film barrier layers make the 3-layer tape totally air tight on the room side (a-value of 0.00 m3/[h·m·(daPa)n]). Uncontrolled convection heat losses or draughts via the window connection joint are thus no longer an issue.
This should be particularly welcomed by building owners since the strict separation of internal and external climates brings considerable energy savings, all in line with EnEV requirements and the forthcoming 2020 EU Buildings Directive. This airtight joint sealing also has a positive effect on the building’s energy passport and the blower door test results.
In the functional area, the innovative tape has excellent acoustic and thermal insulation values while, in the weather protection layer, it offers outstanding resistance to driving rain (1,050 Pa). This important aspect can represent an intelligent product solution in view of advancing climate change with the associated violent storms and torrential rain.
Integration of several barrier layers guarantees optimum transportation of humidity to the outside. This allows the joint to dry out rapidly, preventing structural damage due to mould. ISO-BLOCO HYBRATEC thus conforms to the “inside tighter than outside” principle of the RAL “Installation guide” and has three sealing layers that work independently of one another.
“Total air-tightness, maximum thermal protection and high resistance to driving rain to take account of climate change, combined with long-term capacity to absorb movement; these are mandatory requirements for modern buildings, passive and zero-energy houses,” stresses Andreas Lange, Technology & Training Manager at ISO-Chemie. He firmly believes that planners, installers and building owners will be wise if they use the unique hybrid technology of ISO-BLOCO HYBRATEC! ISO-Chemie provides a 10-year functional warranty for the BG 1 and BG R-certified multi-functional joint sealing tape.
Ease of installation and excellent functional reliability
The impregnated PUR soft foam is self-adhesive on one side for ease of installation. The tape is stuck to the window frame in a single step. This can reduce the time required to less than ¼ compared to conventional window fitting with films.
The multi-functional joint sealing tape’s excellent expansion capacity is also worth a look. It permanently and reliably smooths over uneven joints and absorbs movements. The exceptional range of joint applications enables joints from 6 – 40 mm wide to be reliably sealed with just a single tape dimension. The product is available in tapes widths from 30 – 100 mm to suit the window construction depth.
With the trail-blazing ISO-BLOCO HYBRATEC hybrid technology, ISO-Chemie has made the leap to multi-functional tape 4.0. The building sealing solution manufacturer has already applied for patent protection for its ground-breaking new development.
