5. What is EML? Expanded metal lath
EML is used as a mechanical key for plaster and render. This may be because of the versatility of EML for use internally and externally to form abstract shapes, or because there is not a suitable bond to the background.
As well as being manufactured in galvanised steel it is also made in stainless steel. Ease of cutting with tin snips also add to the versatility of EML.

9. Typical uses Expanded metal lath
Expanded metal lath can be used a carrier for external render, in this case when a layer of insulation has been applied to the external brickwork.

10. Typical uses Expanded metal lath
In this case the EML strips, which come in coils, have been used as a carrier for plaster covering a recessed service pipe. Also used to provide a key on timber wall plates and timber lintels.
