EXAMINATION
A.
Do not begin installation until substrates have been properly prepared.
B.
If substrate preparation is the responsibility of another installer, notify Architect of
unsatisfactory preparation before proceeding.
PREPARATION
A.
Clean surfaces thoroughly prior to installation.
B.
Prepare surfaces using the methods recommended by the manufacturer for
achieving the best result for the substrate under the project conditions.
INSTALLATION
A.
Install in accordance with manufacturer's instructions and approved submittals.
B.
For exterior applications, comply with local codes and structural engineer's fastening
calculations along with manufacturer's recommendations for fastener spacing.
EXTERIOR CLADDING FOR RAINSCREEN APPLICATIONS
A.
Detailing Requirements:
1.
Air space at top and bottom of building or wall termination shall be 1/ 2 inch to
3/4 inch (12 mm to 20 mm) to facilitate airflow from behind the panels. Do not
block vertical airflow at windows, doors, eaves, or at the base of the building.
Airflow shall be continuous from bottom to top so there is air movement
behind each panel. For walls over 60 feet high (18 m), the ventilated cavity
between rear of panels and exterior wall shall be increased to 1-1/4 inches
(30 mm). Air flow behind the cement fiber panels is critical to the performance
of the rain screen constructions.
2.
Fasteners in profile shall accommodate thermal expansion/contraction of

metal and not interfere with panel application.
Install panels from top of building to bottom.
For straight walls, start panel installation in center and work outward.
For walls with inside corners, start installation at corner and work across wall.
Pattern: Straight pattern with vertical panels. Panel size as indicated.
Pattern: Straight pattern with horizontal panels. Panel size as indicated.
Pattern: Semi pattern with horizontal panels. Panel size as indicated.
B.
Rain Screen Installation: Comply with manufacturer's installation requirements.
C.
This product has been designed and tested to comply with the Requirements of the
Florida Building Code 2007 edition including High Velocity Hurricane Zone (HVHZ),
TAS 202 and TAS 203.

Performed by Engineers: Ted Berman & Associates, Al Farooq Corporation,
Fenestrations Testing Laboratories, and Nu-Wind Engineering, Report No. FL
14677 dated 6/23/2011.
2.
Compliance is reserved for construction as tested. Refer to manufacturer
literature for construction necessary to meet building code requirements.
3.
Anchors shall be as listed, spaced as shown on the report details. Anchors
embedment to base material shall be beyond wall dressing or stucco.
Anchoring and loading conditions of the supporting primary structural system
are not part of the evaluation or testing. Materials including but not limited to
steel/metal screws that come into contact with other dissimilar materials shall
meet the requirements of 2007 Florida Building Code section 2003.8.4.
PROTECTION
A.
Protect installed products until completion of project.
B.
Touch-up, repair or replace damaged products before Substantial Completion.
