EML

EML stands for expanded metal lath. EML is used under plaster and render where it provides a good key for the applied surface finish, helps to control cracks and also provides additional strength across a repaired crack.

Thermal cracking affects most masonry structures. All building materials move as a function of expansion and contraction caused by variations in temperature. These movements generate stresses within the materials. When the stresses reach a certain magnitude, the material cracks and effectively forms a movement joint to allow the expansion and contraction to continue.
