lath

The 60 schools in the county that were checked for potentially unsafe ceilings were old buildings constructed using lath and plaster, which can crack and collapse if damaged.

The DfE previously said it was liaising with the county council for updates and there was "no evidence of there being systematic issues with lath and plaster".

Inspections were launched after a ceiling - made out of lath and plaster - partly collapsed at a Synergy Education Trust academy.

The council said there were no concerns about the material, but ceilings may be at risk if the lath and plaster - often found above suspended ceilings - were damaged.

An acre-sized lath house provided shade for tender seedlings, and an innovative rainwater collection system provided water for irrigation six months of the year.
