Stc steel roof.

Trusses supporting metal roof deck panels covered by 1 2 12 7 mm regular gypsum sheathing either loose laid or adhesively or mechanically attached to roof deck. 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. Sound transmission loss properties of a wall or roof is the sound transmission class stc. Project is within an air force approach zone.

Steel cornerbead 1 1 2 38 mm flanges applied with 1 25 mm type s. 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 higher the stc value the better a construction reduces the transmission of sound. Fire resistance ratings for veneer and conventional systems can minimize or eliminate irregularities such as ridging boarding and nail pops associated with standard drywall.

Building is utilizing common wood trusses with concrete tile roofing and insulation directly beneath roof deck to avoid venting read penetrations. In typical metal building construction the values for stc range from a low of about 20 to a high of 55. The standard requires a minimum laboratory stc rating of 50 for party walls and floor ceilings. Will also be providing acoustical ceiling grid tiles throughout.

Zoning overlay requires roof wall stc 65.
