           ensure color consistency throughout product line.  Please specify paint quoted 
           to be as good or equal to the Akzo Nobel listed above. 

PART 3 - EXECUTION

3.1  EXAMINATION

A.	Verify that openings provide an acceptable anchoring surface, being clean, level, plumb, and dimensionally within the manufacturer’s tolerance of clearance spacing.
	
B.	Correct unacceptable openings as required prior to installation.

3.2  INSTALLATION

A.	Install windows and accessories in accordance with approved shop drawings and manufacturer's recommendations.
	
B.	Securely fasten frames, and set units level, plumb, and square with respect to the surrounding structure, without twist or bow. 
	
C.	Place insulation materials around shim spaces as required to ensure continuity of the thermal barrier of the structure.
	
D.	Apply caulk all around between the aluminum frame and the structure, ensuring that a continuous airtight and watertight perimeter seal results.  Leave exposed surfaces clean and free of caulk.

3.3  ADJUSTING AND CLEANING 

A.	Leave units thoroughly clean and free of dirt or other construction residue.
