Installation

Check structural elements and adjoining wall panels.  Verify governing dimensions.  Confirm conditions satisfactory before proceeding.

Allow for dimensional tolerances and deviation from true plane permissible in wall panels and structural frame.  Erect dome units plumb, level and true to building lines, in correct relation to work of other Sections and establish fines and levels indicated.

Provide anchors required for casting in.  Comply with details on approved shop and erected drawings.  Ensure that anchor bolts, embedded properly located and positioned.  Execute all drilling of concrete or steel for supplementary inserts required.

Separate aluminium and steel surfaces in contact with concrete surfaces and other dissimilar metals PVC sheet.

Joints and intersections shall be accurately fitted in true planes, free of distortion, waves, twists, buckles or other defects detrimental to appearance or performance.  Prevent damage to metal finish.  Accurately position, securely anchor steel mullion reinforcement.  Exercise care in assembly of expansion joints to ensure joint function and that resilient seals are correctly positioned to provide complete unbroken weather barrier.

Install cut-offs at exterior to adjoining materials.  Caulk and seal junctions to provide weather tight seals.  Fit flexible seals, tapes and gaskets at locations required to provide water, weather tight junctions.  Ensure seal at end joints between lengths of materials.  Seal junctions of system components to themselves and other work with sealant to maintain effective vapour, air and water barrier.  Clean spaces and joints to be caulked of foreign matter that would injure bond, wipe all metal surfaces to be sealed with cellulose sponges or clean rags soaked with ethyl alcohol, a ketone solvent , Xylol to Toluol and wipe dry with clean cloth; primer surfaces.  Where joints are 13 mm deep or deeper, back sealant with joint backing.  Mask surfaces where required.  Sealant bead depth shall be half width, but not less than 6mm.  Apply sealants with pressure gun having proper sized nozzle to fit the various joints.  Use sufficient pressure to fill the joints.  Tool and finish joints. Immediately clean adjacent materials which have been soiled.

Pack between frames and masonry and concrete with low density fibrous glass insulation.
