Stc Steel Roof

Zoning overlay requires roof wall stc 65.

Stc steel roof.

5 or 6 points in laboratory stc ratings for essentially similar assemblies. 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.

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. Will also be providing acoustical ceiling grid tiles throughout. Sound transmission loss properties of a wall or roof is the sound transmission class stc.

Insulation thickness has a more significant effect on stc ratings than does density for a typical steel stud wall construction the first inch of fiber glass insulation can increase the stc value 6 or more points each additional inch of fiber glass insulation increases the stc value from one to two points conversely density variations have minimal effect on the stc rating see table 2. 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.
