So I had this installed yesterday - I think it's fantastic!
I got the idea for Rockwood cladding from Rodney Gold and actually - aside from looking great - it's a decent sound absorption material (http://www.rockwoodcladding.co.za/pdf/acoustic-values.pdf) to maybe tame the echo in some rooms or frequency points. They have traditionally been only in KZN and CPT, but they've got someone that can do installations in the Johannesburg area. If anyone in the Johannesburg area want to call the installer direct, just PM me and I'll send his cell.
