ISO-BLOCO ONE is a special multi-functional all-in-one joint sealing tape with outstanding properties. The ore-compressed tape is 100% airtight at the internal seal area, contributing in minimising heat loss by convection. It also possesses an optimal vapour diffusion gradient from the inside outwards, enhancing the external transmission of moisture, and enabling the joints to dry out quickly.

Key points :

3-level-sealant with just one product

Reduces convection heat loss

High functional reliability due to large expansion ability

Sealing a wide range of joint sizes with a minimum of tape dimensions

Easy one-step application for a reliable seal

Significant cost advantage through time-saving installation
