Mae Llywodraeth Cymru wedi ysgrifennu at awdurdodau lleol, awdurdodau esgobaethol, Sefydliadau Addysg Bellach a CCAUC mewn perthynas â phresenoldeb deunyddiau ACM ar adeiladau sy’n bodloni’r trothwyon uchder mewn canllawiau a gyhoeddwyd gan Lywodraeth y DU. Nid oes unrhyw adeiladau ysgol neu sefydliadau AB sy’n bodloni’r meini prawf wedi’u nodi hyd yma. Mewn perthynas â’r sector AU, rydym yn parhau i weithio gyda CCAUC a phrifysgolion i nodi adeiladau â chladin ACM sy’n bodloni’r trothwyon y mae’n ofynnol i ni brofi eu samplau. Rydym yn gweithio’n agos hefyd gyda CCAUC ac awdurdodau lleol i sicrhau ein bod yn nodi llety myfyrwyr tyrau uchel yn y sector preifat y mae’n bosib y bydd angen cymryd camau pellach yn eu cylch. Ar hyn o bryd, mae tair prifysgol wedi nodi adeiladau isel sy’n eiddo i’r brifysgol sydd ag ACM ac yn ystyried, neu wedi cymryd, camau rhagofalus, gan gynnwys profi samplau, neu wedi derbyn cadarnhad annibynnol (nid gan y BRE) bod y deunydd inswleiddio o ansawdd gwrth-dân priodol.
The Welsh Government has written to local authorities, diocesan authorities, Further Education Institutions and HEFCW in respect of the presence of ACM materials on  buildings that meet the trigger heights in guidance issued by the UK Government. No school or FE institutions buildings meeting the criteria have been identified to date. In  relation to the HE sector, we continue to work with HEFCW and universities to identify buildings with ACM cladding that meet the trigger heights and, therefore, require sample testing. We are also working closely with HEFCW and local authorities to ensure we identify high-rise private-sector student accommodation that may require further action. At present, three universities have identified low-rise university-owned buildings with ACM and are considering, or have taken, precautionary measures, including sample testing, or have received independent (non-BRE) confirmation that the insulation is of appropriate fire retardant quality.
