Group 5.5 Commercial Window and Door Installation, Part 1: Overview Flashcards
AAMA IPCB-08 is referenced throughout this section. and addresses the installation of
Windows and exterior doors only.
AAMA IPCB-08 also includes installation of storefront and curtain wall systems. T or F.

AAMA Standard Practice for the Installation of Windows and Doors in Commercial Buildings:
AAMA IPCB-08
Commercial Installations follow-the same three key principles as residential installations:
Product is only as good as the Installation
Product must integrate with the WRB
Proper Sequencing is essential.
In contrast with residential installations, commercial projects require more of these (3) practices.
C.A.D.
- C - Coordination - greater need for interface with other contractors
- A - Accessories: more use of accessories, particularly receptor systems
- D - Drawings - more Reliance on shop drawings
Windows and doors for commercial installations are generally built to a performance class of ___ or ____AW.
CW and AW
. ___ and ___ Class windows may also be used in commercial projects, especially if they are tested to higher optional performance grade levels.
R and LC
Commercial window projects are typically made of ____ due its high strength to weight ratio.
These other two materials are also used:
Aluminum.
Fiberglass and Reinforced PVC
Commercial windows joined together area called ___ when assembled horizontally and ____ when combined vertically.
Horizontal Ribbon
Vertical Stack
Key areas objectives requiring coordination on commercial installations include (3):
DMC
Design Intent
Movement
Clearance provisions
A significant source of movement concerning commercial product installation is:
Thermal expansion.
Which of these materials experiences the greatest amount of thermal movement:
Aluminum Rigid PVC Glass Reinforced Polyester Wood Steel
Rigid PVC
In and 8 foot sample, about how much (maximum) movement would a 100 degree temperature change create for each of the following: Wood Steel Glass Reinforced Polyester Aluminum Rigid PVC
0.025” Wood
0.065” Steel
.140” Glass Reinforced Polyester
.130” Aluminum
0.44” Rigid PVC
The amount of thermal movement experienced by PVC is about ___ times that of steel.
7
Other sources of movement include:
2 + 1
Live loads
Seismic events
(Wind)
Installation accessory items include items in these five primary categories:
mullions panning subsills receptor systems cladding
There are four primary types of mullions used connect ribbon and stack window arrays, they include:
Hint: HIST
H - H (or horizontal stack) mullions
I - INTEGRAL mullions - Male / Female
S - Independent STRUCTURAL Mullions
T - THREE -piece mullions.
Male and female integral mullions are manufactured ____ the unit and designed to ____ to form the connection.
(Two distinct descriptors)
…manufactured as part of the unit and designed to slip together to form the connection
Independent structural mullions are typically attached to the ___ and ____.
Receptor and subsill.
Vertical and Horizontal Stack mullions come in two variations:
H mullions (visble) and Zero Site Line (concealed)
Panning is provided for two primary functions ____ and ____ but may also be designed to _____.
Anchoring and Covering an existing frame
Replicate existing trim.
An array of specially formed shapes typically used on the exterior of windows and doors in new construction and replacement work to facilitate anchoring of the product and cover an existing frame.
Panning.
Panning is generally used around the entire perimeter and is either pre-attached to the new window frame - called ____ panning, or attached to the opening before window installation, called ____ panning.
Wrap around Paning
Preset Panning
Subsills include ______ - upturned end edges
designed to stop the flow of water out of the ends
of the sill into the wall cavity.
End Dams
Sub sill end dams must be high enough to:
Contain collected water as it drains to the outside.
By using _________ _____ or extended flanges, the
subsills can be shimmed level and attached in
place. This makes working with multiple ribbon
windows easier because the subsill can offer a
________ _____ ______ for installation of the
windows or doors.
anchor clips
continuous, level track
Windows and doors used in surface barrier
systems are attached to the structure through the
frame or may be installed in a _____ ______
which is attached to the structure.
Because live load movement from the floor above
can often exceed the designed movement of a
typical sealant joint, receptors are often used to
“float” with the floor and allow for building
movement at the head of an assembly.
Like subsills, receptors offer the advantage of
providing a continuous track which is ideal in
multiple window configurations.
receptor system
Receptors, also known as _____ ______ are
generally composed of one- or two-piece
extruded members used at the head and jambs of
windows.
“Comp Channels,”
Receptors are used to facilitate the installation
and to allow for ____ _____ due to ______ ______
without disrupting the sealant.
building movement
live loads and thermal movement
Receptors are usually shaped like a _______ and
typically include _______ which form a
compression seal against the framing system.
channel
gaskets
The receptor is generally shimmed and attached
in place, allowing for a sealant joint between it
and the _____.
building surface barrier material
Cladding is used to ____ or ____ openings.
Close off / cover.
When cladding materials are used to cover large
voids, the voids should be_______ to maintain
the______ integrity of the completed
installation.
Insulated
thermal
In general there are five basic steps for proper joint preparation and sealant application. Name and describe each.
Clean – Joint surfaces must be clean, dry,
dust free and frost free
• Prime – If required, primer is applied to
the clean surface(s)
• Pack – Install backer rod or bond breaker
as required
• Shoot – Sealant is applied by “pushing the
bead” into the joint cavity
• Tool – Dry tooling techniques are used to
strike a flush joint and make certain the
sealant has the proper configuration and
fully contacts the joint walls
Quiz Question 1:
Which of the following is not a typical source of building movement?
thermal expansion
seismic forces
interstory drift
anchor conditions
Anchor conditions
Quiz Question 2:
Which of the following is not a common type of mullion:
Male/female integral
horizontal ribbon and vertical stack
independent Structural
Three piece
Horizontal ribbon and vertical stack
This would be a correct answer with the sequence flipped: Vertical ribbon and horizontal stack mullions.
The adjective refers to the direction of the mullion piece, not the orientation of the overall assembly.
Quiz Question 3:
Pre-set panning is:
Installed to the existing opening prior to window installation
pre-attached to the new window frame
attached to the subsill only
attached only at the jambs.
Installed to the existing opening prior to window installation
Quiz Question 4:
End dams of ___ must be high enough to contain collected water until it drains out.
panning
receptors
subsills
mullions
subsills
Quiz Question 5:
Which of the following is specifically intended to allow for building movement, expansion/contraction and to adapt to installation tolerances?
receptor
subsills
panning
head expander
receptor
