Reduces Vertical Spread And Increases Horizontal Spread.

Reduces vertical dispersion and increases horizontal dispersion.

It will decrease vertical spread while increasing the horizontal spread.

This will make it easier for the roots to establish a foothold and begin their horizontal spread.

The cavity emits horizontally propagating a light beam through one faceted end into the adjoining beam-deflecting section.

IA1 - stromal invasion less than 3 mm in depth and 7 mm or less in horizontal spread

IA1 – stromal invasion less than 3 mm in depth and 7 mm or less in horizontal spread

A concrete wall stabilises the stored materials, which prevents a horizontal spread of the fire.
