ISO-BLOCO ONE is a special multi-functional all-in-one joint sealing tape.
With a low a-value of zero, the pre-compressed tape is 100% airtight at the internal seal area, 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.
It also has a high movement accommodation factor (500%) and a high driving rain resistance, with a minimum of 1000 Pa (greater than Hurricane Force 12).
