ISO-BLOCO One is a special multi-functional all-in-one
joint sealing tape with outstanding properties. Having a
revolutionary low a-value of Zero the pre-compressed
tape is 100 % airtight at the internal seal area,
contributing enormously in minimising heat loss by
convection. It also possesses an optimal vapour diffusion
gradient from the inside outwards (50:1) enhancing the
external transmission of moisture, enabling the joints to
dry out quicker. Having an exceedingly high movement
accommodation factor (500 %) and an extraordinarily
high driving rain resistance with a minimum of 1,000 Pa
(greater than Hurricane Force 12) it outperforms
conventional impregnated sealing tapes.

Applications

This all-in-one PUR-flexible foam sealant tape combines all
the requirements of the energy savings regulations (EnEv),
the RAL installation instructions and the UK Building
Regulations in one product. It is particularly suitable for the
reliable, uncomplicated and time saving perimeter sealing
of windows and doors. This intelligent joint sealing tape
functions around the 3-level-principal. Externally it provides
high resistance to driven rain, within the middle area it
provides thermal and acoustic insulation and internally it is
absolutely airtight as well as a water vapour barrier.
