Part 3 — Execution

3.1 Installation

  1. General:  Install windows per approved shop drawings, in proper relation to adjoining construction.  Do not twist frames or force fit them into poorly prepared openings.  Anchor windows as required to satisfy design requirements.  See manufacturer’s installation instructions and shop drawings.
  2. Center window units in wall openings leaving a uniform interface caulking recess on all four sides.  The manufacturer strongly suggests that sealant be selected for its adhesion compatibility with the specified exterior wood and adjacent wall materials.  Consult the manufacturer for recommended sealant.
  3. Level Units:  Install shims at bearing locations, anchors, and latch-point, so they are not dislodged by subsequent operations.  Test sash operation and sash alignment before permanently anchoring units.
  4. Anchorage:  Install anchors through frame centerline beside shims.  Anchor window units to wood blocking with wood screws and to metal framing with toggle bolts; countersink anchor heads.  All anchors shall be concealed by closed sash or, in the case of fixed units, with plugs.
  5. Installation to conform to window manufacturer’s requirements as indicated in the manufacturer’s technical manual.

3.2 Cleaning

After installation is complete and surrounding work is substantially complete, installation contractor is to clean and lubricate all hinges and pivots.

3.3 Protection

Institute protective measures required throughout the construction period to ensure that both interior and exterior of wood windows will be without damage or deterioration, other than normal weathering.
