Mae Llywodraeth Cymru eisoes wedi cymryd nifer o gamau i wella diogelwch adeiladau. Fis Ionawr diwethaf, yn dilyn newid i reoliadau, gwaharddwyd defnyddio deunyddiau llosgadwy mewn systemau cladin yng Nghymru. Roedd hyn yn berthnasol i bob adeilad preswyl newydd (fflatiau, llety myfyrwyr a chartrefi gofal) ac ysbytai dros 18m o daldra.
The Welsh Government has already taken a number of steps to improve building safety. Last January, following a change to regulations, the use of combustible materials in cladding systems was banned in Wales. This applied to all new residential buildings (flats, student accommodation and care homes) and hospitals over 18m in height.
