The New Sound Standard
R-stud meets CCRR, E119 & STC testing. The acoustical testing alone shows R-stud’s performance 3-5/8” stud @ 24”o.c. using R-13 unfaced insulation with one layer of 5/8” gypsum type X provides a 50 STC (Sound Transmission Class) rating, beating generic steel studs by nine points...saves money by using less materials like gypsum board and less labor installing that extra layer. The design in R-stud significantly increases product performance, including greater load capacity, higher limiting heights, better acoustical, better R-values and easier installation.
