Appreciate reading everyone's comments on this issue of Tiles v Iron  (thanks for your extensive explanation, Jenny).

Our residential complex is starting to have problems with the decramastic (spell' ?) sheeting – it's about 25 yrs old and some roofing has developed holes/ leaking.  The body corp will no doubt decide to run with Colorbond,  BUT rain noise IS an issue partic in our kitchen/dining/lounge (where the ceiling is raked, so no batts in ceiling cavity to muffle it).

Is it possible to get confirmation from anyone out there that the owners paying the extra $$ to install Anticon underneath (glass wool with foil),  rather than the basic Sisolation/sarking,  will give a noticeable difference in noise reduction ? ?

Thanks, Bev
