Application

Suitable for perimeter sealing of windows and doors.

Description

A special multi-functional all-in-one joint sealing tape with outstanding properties. The pre-compressed tape is 100% airtight at the internal seal area, contributing in minimizing 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. With a very high movement accommodation factor (500%) and a high driving rain resistance with a minimum of 1000 Pa (greater than Hurricane Force 12), it outperforms conventional impregnated sealing tapes. The intelligent joint sealing tape functions around the three-level principal. Externally it provides high resistance to driven rain, within the middle area it provides thermal and acoustic insulation and internally it is airtight as well as a water vapour barrier.


Features and benefits:

  • Three-level sealant in one product.
  • Resistant to driven rain in excess of 1000 Pa (ift 105 35450).
  • Optimal outwards vapour diffusion.
  • Reduces convection heat loss.
  • High movement accommodation factor (MAF: 500%).
  • Seals 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.
  • Suitable for passive house construction.
  • Can be installed in adverse weather conditions.
  • Complies with the EnEV requirements, RAL window installation principals and the UK Building Regulations.
