Group 5.6 Commercial Window and Door Installation, Part 2: Installation Preparation Flashcards
Variables that should be assessed prior to commercial fenestration installations include:
Preliminary site inspections
For commercial installations, it is more important to
conduct preliminary inspections at what point in the construction process
Before starting the job.
Among other factors, preliminary inspections involve assessing several variables. These include:
- Types of Buildings and Components

- Health and Safety Issues
Types of Buildings and Components might include:
- Masonry or Concrete Block
- Pre-cast Concrete
- Wood Frame
- Steel Stud
Before replacing old windows or doors,
installers should check for evidence of damage _______ and ______ as indicated by stains, mold or mildew.
Condensation and water leakage.
A third consideration in a preliminary inspection is the type of water resistive barrier system (WRB).

The amount of additional clearance required to accommodate accessory items is often
called:

Deducts
Excess
Deducts.
All measurements should be accurate within accepted
_____ as suggested by window manufacturers.
tolerances or deviations (plus or minus) from plumb, level and square

After
While
Before
Preset panning can be advantageous because the installer can apply the ______ ____ prior to installing the new window.
perimeter seal
Once the preset panning is assembled, the pre-set panning assembly is placed nto the opening to _____ ___ ____. This helps to establish the amount of trimming necessary.
Check the fit
As the trimmed and sealed, pre-set panning is installed into the opening, shims are used to ensure the panning is ___, ___ and ____.
plumb, level and square.
To complete the installation of the preset panning,
______ ___ or ___ ______ tape is applied around the
perimeter between the panning flange and pressure
plate and the building condition. Then, sealant is
applied and tooled into the joints.
backer rod
bond breaker tape
In openings where mullions must remain, the exterior
_________ is applied over the two opposing
panning pieces flanking the mullion.
