Durox Thin Joint System - Fast Build Masonry Construction 

Thin joint blockwork

Durox System is a fast-build method of masonry construction suited to all types of buildings. It is a versatile building technique that is recognised as a modern method of construction. Durox System combines high quality dimensionally accurate aircrete blocks with a specially formulated quick-setting thin layer mortar.

Benefits of Durox Thin Joint

  • Building faster using Durox System, whether it is a housing or commercial project, can result in construction times equivalent to off-site methods.
  • The build quality has the potential to improve the performance of the building in areas such as air tightness and sound insulation as well as providing an accurate substrate benefiting finishing trades as well as the installation of thermal insulation material.
  • Maximum design flexibility to suit the requirements different plan forms, awkward sites and individual projects.

Environmental performance of Durox Thin Joint

Durox System is manufactured under an ISO 14001 compliant Environmental Management System that is independently certified by BSI. Summary green guide ratings applicable to Durox aircrete blocks can be found in the BRE Green Guide to Specification www.thegreenguide.org.uk.

Durox Thin joint applications

  • Durox System can be used to construct solid or cavity external walls, separating walls and internal walls.
  • With improving standards of thermal insulation there is pressure to conserve valuable wall space. The use of Durox System with external insulation is emerging as a viable and cost effective way of constructing solid external walls capable of meeting any specified level of thermal performance.
