Part 3: Execution

3.1 Suspended

Install acoustical material and suspension system, including

necessary hangers, grillage, splines and other supporting

hardware, in accordance with ASTM C636, all code requirements

and sound industry practice (such as CISCA guidelines).

3.2 Adhesive

Apply tile with an adhesive manufactured specifically for this

purpose, in accordance with manufacturer's directions, and/or as

follows. Brush off any loose dust from tile back surfaces and

prime them where adhesive is to be applied. This lays down any

residual dust to assure good adhesion. Prime only a 2-3" circle

near each corner by buttering a very thin coat of adhesive with

trowel blade at a 45 degree angle. Then apply a walnut-sized

dab of adhesive to each of the 4 circles and press tile firmly

in place. Insert splines in kerfs at corners of units. Foil-

backed ACOUSTONE tile should not be adhesively applied.

3.3 ACOUSTONE "F" Fissured Tile

Intermix tile from 4 or more cartons to obtain uniform

distribution of fissure variations.

3.4 The ILLUSION Ceiling Series Exposed Grid Suspension

Install inverted tee, direct-hung, exposed surface system having

low-gloss finish and color of the ILLUSION Ceiling Series.

System should meet "intermediate" or better structural standards

of ASTM C635.

3.5 Fire-Rated Suspension

Install suspension per UL Design No. ( ) and ASTM C636.

3.6 Light Fixture Protection

Install light fixture protection and necessary hangers and ties

in accordance with UL Design No. ( ) and ASTM C636.

3.7 Ceiling Sound Insulation

Lay blankets flat on ceiling panels and tightly fit around all

grillage, hangers and other vertical penetrations:

3.7.1 Single-Layer

Over entire ceiling.

3.7.2 Double-Layer

3" total thickness, over that part of ceiling extending 48" on

each side of all partitions.

3.8 Plenum Sound Barriers

Install THERMAFIBER blankets; cut vertical blankets as necessary

to clear plenum obstructions:

3.8.1 Upside Down "T"

Lay horizontal blankets on ceiling grid extending 1' on either

side of partition centerline and lean vertical blankets against

hanger wires for support.

3.8.2 Vertical Barrier

Lean vertical blankets against hanger wires for support over

partition centerline.

3.8.3 Tent Barrier

Lean blankets together over partition centerline and wire or

clip tops together.
