Stc Steel Roof

Stc steel roof. The higher the stc value the better a construction reduces the transmission of sound. Building is utilizing common wood trusses with concrete tile roofing and insulation directly beneath roof deck to avoid venting read penetrations. This is usu ally because there is a pronounced dip in the test curve and the stc rating is heavily influenced by a measurement in one fre quency band. Veneer plaster partitions achieve up to 63 stc in steel framed resilient systems and up to 52 stc in wood framed resilient systems have achieved 1 to 4 hr.
The standard requires a minimum laboratory stc rating of 50 for party walls and floor ceilings. Fire resistance ratings for veneer and conventional systems can minimize or eliminate irregularities such as ridging boarding and nail pops associated with standard drywall. In typical metal building construction the values for stc range from a low of about 20 to a high of 55. Zoning overlay requires roof wall stc 65.
