[font='Times New Roman','serif']Hi All- Hoping you might be able to help. In renovating my mom’s condo, Luna proposed using a Scuba Thermal Silent (ST46) underlay. They say it’s rated to 67dB IIC and STC. However, her condo management company/board have denied that product and instead are requiring ½ inch cork (not just quarter inch) without any supporting documentation. It wouldn’t matter except that this is going to increase the cost of her floor project by about 50% from 8k to 12k. I’m desperate to get my hands on any industry insight about the comparison of ½ cork verses the ST product. I don't know the type of subfloor - just that it is concrete.
