The multi-functional tape with integrated film barrier

Reliable prevention of convective heat loss

ISO-BLOCO MULTITEC is an MF1-tested pre-compressed multi-functional tape with hybrid technology for creating 3-layer seals around window, door and other connection joints that are air tight, impermeable to driving rain and thermally insulating. This hybrid combination of flexible, impregnated foam and an air tight, moisture-regulating membrane film layer provides reliable and cost-effective joint sealing in accordance with the “inside tighter than outside” principle. Even when subject to extreme climate changes, ISO-BLOCO MULTITEC offers excellent structural movement compensation and due to its ability to continuously absorb movement; reliably prevents convection heat loss.

Application Areas

High functional range for all dimensions

ISO-BLOCO MULTITEC is the hybrid further development of conventional multi-functional tapes with integrated film barrier layer. It is ideal for the requirements of energy-efficient joint sealing when installing windows or doors and when sealing structural and modular elements. In new builds and renovations, ISO-BLOCO MULTITEC can be applied directly to the building structure in combination with supporting frames and can be used for in front of wall installation in the insulation level. It offers the specified airtightness and maximum thermal protection for all types of building (e.g. KfW energy-efficient houses, passive houses and plus energy houses).
