Group 5.3 - Residential Window & Door Installation - Key Principles Flashcards
The three key principals to successful fenestration installation are:
- Product is only as good as the Installation
- Product must integrate with the WRB
- Proper Sequencing is essential.
Code-cited standards for windows, doors and skylights are:
- North-American Fenestration Standard
AAMA /WDMA/CSA 101/1.5.2/A440
Effective window integration with the WRB depends on:
Square and plumb installation
Proper construction sequencing
Passing an air infiltration test per AAMA 783
Proper construction sequencing
What are the two different WRB systems commonly used to form the water-shedding system of the envelope?
Surface barrier systems
Membrane drainage systems.
In a surface barrier system, the_____ surface of the wall or roof poses the sole barrier to water intrusion.
Membrane
Outermost
Interior
Outermost.
Surface barrier wall systems are often solid walls. List 4 examples of surface barrier wall systems.
Single Width masonry
Poured (CIP) concrete
Glass fiber reinforced concrete
Concrete Block.
What is the one method of joining a window with the wall in a barrier system?
Sealant.
In a membrane drainage system water that passes the exterior cladding encounters a _____ behind the finish.
Concealed membrane.
IRC requires ______behind all forms of siding materials in new homes.
a weather resistive barrier
Windows are produced in two basic installation configurations. What are they?
Flanged, Non Flanged (block-frame.)
How is a block-frame window attached to the rough-opening?
Through a mounting flange
Fasteners driven through the jambs
Installation clips or brackets
Fasteners driven through the jambs
Installation clips or brackets
There are four categories of flange-type windows, what are they?
Integral structural flanges
Integral non-structural flanges
Applied structural flanges
Applied non-structural flanges
What is the difference between applied flanges and integral flanges?
Integral flanges are manufactured as part of the fenestration unit. Applied flanges are snapped in, or attached to the frame after the window is complete.
Four additional requirements for integrating a window into the WRB are:
(These are product/system categories required).
Installation accessories
Anchoring devices
Flashing
Sealant
Installation accessories include:
(List 5).
panning sub-sills receptors drip-caps Trim (interior or exterior)
What are the consequences of over shimming and under-shimming?
Over - causes inward bow of jambs
Under - allows the unit to sag out of square
Both can cause improper sash operation
Setting shims are placed at what part of the window perimeter?
At the sill.
What is the minimum material load bearing capacity for setting shims?
1,100 psi.
Can wood shims be used under the sill?
No. Wood shims are not permitted.
Lateral shims are places at the window _____ and should always be located directly under/behind a _____.
Jambs
Fastener
Shims are classified by material and/or style, including these three styles:
Flat shims
Rectangular
Horseshoe
Sealant for window or door installations should be based on what standard?
AAMA 800
Quiz Question
1. Which of the strategies for shedding water from wall systems provides a water and moisture barrier at the outermost plane of the wall?
Surface barrier systems
Water resistive barriers
membrane/drainage systems
exterior insulation and finish systems.
Surface barrier systems
Quiz Question
2. True or false: A mounting flange or fin is intended to serve as a water penetration barrier
False
Quiz Question
3. The major components that serve to integrate the window with the water-resistive barrier are:
head expanders and jamb extensions
drip caps and cladding
panning and subsills
flashing and sealants
flashing and sealants
Quiz Question
4. Wood Shims:
are located under the sill and ata the jambs in order to square a window
Are not permitted under the sill
Are a direct replacement for plastic and metal shims
are also known as “setting shims”
Are not permitted under the sill.
Quiz Question
5. Which of the following is not true of shims?
lateral shims are placed at the jambs to square a window
laterals shims should be located directly under a fastener
Setting shims and lateral shims are made of wood or high-impact plastic.
some jurisdictions may require the use of metal shims for fire resistance
Setting shims and lateral shims are made of wood or high-impact plastic.
