,,.,,� - High density of THEAMAFIBER SAFBs makes them resist sagging and stand up better in stud cavities.
- Iiign tire protection—ems to fire performance of marry assemblies.
- Efficient sound performance—adds STCs to wall and floor-ceiling sound ratings.
- Special details—can be used in acoustical ceilings as overlayment to reduce flanking sound;"creased"sys-
tems provide additional sound performance through acoustic engineering.
Description ,M,-,,,, ,;ter,_ THERMAFIBEri Sound Attenuation Fire Blankets(SAFE))are the best way to stop sound in wall and flour-ceiling
assemblies.Because Tt•>FriinAAerat Sound Attenuation Fire Bby-product of
Blankets are manufactured tram slag,a
R iron ore reduction,and naturally occurring rock,the mineral fiber in THERMAFIBEH Blankets is highly resistant to
, ,a Te.Thus many of the systems this product is used in have high fire ratings as well as sound ratings.A fire test
\t,t conducted according to ASTM E119 test procedure showed that TH1NMAFI3taa Insulation remained intact at
, • .°• • \t. temperatures in excess of 2,000°F for five hours.
Tests prove that THERMAFIBER SAFB is the best performance value for multi-family residential projects,hotels
and motels,offices and retail businesses.The mineral fiber blankets are resilient enough to tit wound obstacles,
yet are rigid enough to stand up well in stud cavities.SAFBs are available in two densities,4 pcf(available 1"
thick only)and 2.5 pct(nominal densities).Two types of SAFBs are available,regular and"Creased."Creased
SAFBs are 1"wider than regular blankets and are designed to bow in the stud cavities,providing an"engi-
neered"sound performance.For system Information on asserriUlies containing TrtlemAritc;+i Sound Attenuation
Fire Blankets,see brochure'fF885 or SA100.

apart the verticals are the more load each one carries and the less even the load becomes. This
can cause excessive bending in the member the vertical is attached to. Having a vertical at or
near each joint where it will not cause bending in the member it is attached to is a way of
avoiding this problem. This is the way we are currently applying our factory-applied fillers.
Bracing will be required on the truss bottom chords in filler areas where there is no
sheathing(drywall)directly applied to the truss bottom chord. See the truss drawing for
bracing spacing in filler areas. If the unsheathed part of the bottom chord is shorter than the
required bracing spacing for the bottom chord no bracing is required_
For more information see the standard filler detail sheet that is part of the individual job
paperwork package. If you have any questions please feel free to call me. I can be reached at
