EXAMINATION
A.
3.2
Verification of Conditions: Examine installation location and conditions under which work is to be performed. Verify wet
work is complete and dry. Verify suitable blocking at cable mounting points is in place. Notify Contractor in writing of any

A.
Install products in accordance with manufacturer’s written instructions and in proper relationship with adjacent
construction including the following:
1.
2.
3.
4.
5.
Inspect fabric prior to installation. Do not install damaged, imperfect or soiled fabric.
Apply mounting system tracks to surfaces to receive system. Secure with 1 inch staples spaced on 2 inch
centers.
Install mounting system tracks level and straight, flush and in proper alignment.
Install acoustical core material continuous and flush to the edge of the track in largest sizes practical and secure
in place with appropriate adhesives or staples. For fabric very light in color or light in weight, provide a white
scrim or lining to prevent read through. Scrim or lining shall not inhibit the acoustical performance of the system,
and meet fire safety code requirements.
Stretch shop cut fabric and secure into the locking jaws to produce a smooth surface, free of wrinkles or
puckers. Adjust fabric to meet the required dimensional layout.
