Interlocking nib system

Interlocking nib system

  • It eases the work and improves the quality of the construction by reducing the effort required to correctly align the bricks in order to achieve the desired flatness.

Improved thermal performance

Improved thermal performance

  • Heat losses are reduced due to the nut-and-spindle guide, which decreases thermal transfer through the vertical joints.

Reduced execution time

Reduced execution time

  • Productivity in wall construction increases due to the large size of the bricks, requiring only 9 bricks per square meter.

Reduced consumption of mortar

Reduced consumption of mortar

  • Mortar losses are reduced by eliminating the application of mortar in the vertical joints and by the special geometric configuration of the voids, which reduces the phenomenon of mortar sliding from the horizontal joints inside the brick.
