So I've got three new rads to put on walls that we've had thermaboard put on. Two rads are pretty small (30×1000mm) but the third is a beast at 60×1200mm and about 30kg empty. Plasterer said the thermaboard can take at least 25kg on each fitting - is that right?! Planning to use the biggest hollow wall anchors I can fit through the radiator brackets and put 4 in each bracket...
Will it fall off and take the board with it?!
