Features and Benefits Stops Fire – Formulated exactly the same as Thermafiber Safing Insulation, the mineral fiber composition ofTopStop withstands sustained temperatures above 2000oF, in accordance with ASTM E119. Systems are availablefor head-of-wall firestopping with up to 4-hour fire ratings.

Stops Sound – TopStop provides an effective acoustical barrier as well. It attenuates sound passage across thetop of the wall.

Saves Time – Uniform, pre-shaped TopStop boards eliminate field forming of insulation, while assuring a snug fitof material in the deck flutes. They increase worker productivity by reducing job-site fabrication and the uncertain-ty of installing the correct amount of Safing Insulation required in the many fire-stopping designs.

Saves Material – TopStop eliminates the waste produced by field cutting. And because TopStop’s edges aresmooth, it also reduces the amount of smoke sealant required to complete installation.

Environmentally Friendly – TopStop is composed principally of recycled blast furnace slag from the steel indus-try, yielding a pre-consumer, recycle content of 85%. This material will not wick moisture, promote fungal or bac-terial growth, and will not contribute to corrosion of other materials.

Sized to Fit – There are three standard sizes to fit common fluted roof decks or slabs. Special sizes and densitiesare available.

Thermafiber® TopStop™ Head-of-Wall Insulation is high-density mineral fiber insulation that has been shaped tofit the trapezoidal flutes typical of metal or concrete decking. The composition of these specialized insulationboards matches that of the Thermafiber Safing Insulation commonly called for in UL or OPL approved head-of-wallconstructions. Insulation used for TopStop is UL and OPL Classified, and is approved for use in designs thatotherwise call for Safing Insulation. Available in three common sizes of trapezoidal shaped boards, as well asstandard forming strips, TopStop Insulation speeds the installation of floor-to-ceiling/roof deck firewalls.

• Select TopStop size that fits within the flute space with the correct amount of compression of the insulation in alldirections*. (Follow fire-stop assembly design specifications for correct density and amount of compressionrequired.)

• Cut insulation to a length sufficient to reach from the drywall surface plane on one side of the partition wall to thedrywall surface plane on the other side.

• Insert TopStop insulation in flute recesses so as to completely fill the area between the wall head and the roofdeck. Add TopStop Strips where necessary to fill any gaps left between the top plate of the wall and any flute sur-faces. (Follow fire-stop assembly design specifications for correct density and amount of compression required.)

• Apply smoke sealant as specified in the listed and tested design specification, and according to the smokesealant manufacturer’s instructions.

• Trim with metal or drywall components as called for in design specification.

• Select TopStop size that fits within the flute space with the correct amount of compression of the insulationin all directions.* (Follow fire-stop assembly design specifications for correct density and amount of com-pression required.)

• Cut insulation to a length sufficient to reach from the drywall surface plane on one side of the partition wallto the drywall surface plane on the other side.

• Insert TopStop insulation in flute recess so as to completely fill the area above braced wall head and belowthe roof deck. Add wall top forming strip if required. (Follow fire-stop assembly design specifications for cor-rect density and amount of compression required.)

• Apply smoke sealant as specified in the listed and tested design specification, and according to the smokesealant manufacturer’s instructions.

• Trim with metal or drywall components as called for in design specification.

*Non-standard sizes and alternate densities are available on special order.

Good Design Practices 1. System performance following substitution of materials or compromise in assembly design cannot be certifiedand may result in failure of fire resistance or noise reduction performance under certain conditions. For exam-ple, substitution of low-density glass fiber insulation in place of the Thermafiber TopStop Insulation Board maycompromise fire protection at that point and therefore reduce the performance of the system.

2. Adjacent assemblies should be designed or selected to be of similar fire protection performance. Voids shouldbe filled or otherwise eliminated. Combined performance of adjacent systems will be close to that of the low-est performing element.

3. Penetrations for windows, HVAC, wiring, etc. must be sealed with an appropriate fire-stopping design.

4. See UL or Intertek Testing Services (OPL) Design for specific design criteria and list of approved smokesealant manufacturers.
