ISO-BLOCO ONE

Product description

Product advantages

ISO-BLOCO ONE is a special multi-functional all-in-one joint sealing tape with outstanding properties. Having an a-value of 0,00 m³/[h*m*(daPa)²⁄ ³] the precompressed 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 (40:1) enhancing the external transmission of moisture, enabling the joints to dry out quicker.

3-level-sealant with just one product
Resistant to driven rain in excess of 1050 Pa
Optimal outwards vapour diffusion
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
Certified Passive House component
Can be installed in adverse weather conditions
Complies with the EnEV requirements, RAL window installation principals and the UK Building Regulations
10 year performance guarantee*

*On the conditions of the manufacturer (available upon request).

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, with more than 1050 Pa, 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.
