Learning ObjectivesAt the end of this program, participants will be able to:

Examine the evolution of window standards and code references

Identify the North American Fenestration Standard:

(NAFS-08) AAMA/WDMA/CSA 101/I.S.2/A440-08

and Compare it to previous versions (AAMA/NWWDA 101/I.S.2-97, 101/I.S.2/A440-05)

Recognize and apply NAFS-08 to specify product type, performance level and keyperformance attributes

Understand what the Architectural Window (AW) performance class is, and

recognize the benefits to clients by contrasting its performance grade with theother classes

Interpret AAMA 2603, 2604 & 2605 performance requirements for organic finishes,

for use in specs

Apply the concepts of air, water, structural and life-cycle testing to knowledge

about building integrity, soundness and energy efficiency (HSW)

Test Reports

At least once every four years,

the manufacturer must retest the product to

verify that the design continues to comply withthe standard’s requirements.

Evolution of standards… Five previous performance classes (‟97/‟05)

*Listed in order of performance.

Residential/R: Typically one- and two-family dwellings.

Light Commercial/LC: Typically low-rise multi-family,offices, motels, libraries and professional buildings(doctor, dentist, law).

Commercial/C: Typically lighter-use industrial, hotels,and retail sales buildings.

Heavy Commercial/HC: Typically mid-rise hospitals,schools, institutions, dormitories, government or publicbuildings, and facilities where heavy use is expected.Also, commonly used on other buildings with increasedloading requirements.

Architectural Window/AW: Typically larger institutional orhigh-rise / mid-rise buildings to meet increased loadingrequirements, and buildings where possible misuse of thefenestration products is expected.

Definitions of Four New (’08) Performance Classes

R: Commonly used in one- and two-family dwellings.

LC: Commonly used in low-rise and mid-rise multi-family dwellings andother buildings where larger sizes and higher loading requirements are

expected.

AW: Commonly used in mid-rise and high-rise buildings to meetincreased loading requirements and limits on deflection, and in buildingswhere frequent and extreme use of the fenestration products isexpected.

CW: Commonly used in low-rise and mid-rise buildings where larger sizes,higher loading requirements, limits on deflection, and heavy useare expected.

divided by 175 = Maximum deflection.

Example:

AAMA 502

AAMA 502 refers to field testing offenestration products and allowable

performance values.

Air Infiltration: Field air infiltration ispermitted to be 1.5 times design values.

Water Penetration: Field water pressure is

allowable at 2/3 of design pressure.

AAMA 910Life Cycle Testing

7/23/2019 fs11-1320345716-87219


Life Cycle TestingRequired on AW –

the most significant difference versus CW product

“To model through…actual performance”

Equivalent to 7 years of everyday use.

7/23/2019 fs11-1320345716-87219


Life Cycle Testing

Required for AW Three Steps of Life Cycle Testing for the

Architectural Window (AW) AAMA rating:

1.

TESTING: Testing the Window for Air Infiltration,Water Penetration, Uniform Structural &Operating Force.

2. Cycle Test Including MISUSE: Cycles of misuse

and abuse.

3. RE-TESTING: Repeat Air Infiltration, WaterPenetration testing & Operating Force.

7/23/2019 fs11-1320345716-87219


Life Cycle TestingRequired for AW

(optional for other classes)

Vent Cycling Testing:

Operating ( 2,500 cycles )

* 1,250 cycles of, Opened and Closed, Locked andUnlocked

* 5 cycles of Misuse and Abuse

* 1,250 cycles of, Opened and Closed, Locked and

Unlocked

7/23/2019 fs11-1320345716-87219


Performance Testing

After Life Cycle TestingRequired for AW(optional for other classes)

Repeat Air Infiltration Testing

Repeat Water Penetration Testing

Verify Operating Force

Must pass all or does not achieve AW rating.

Specifying AW Products

When should AW Products be specified?

How are budgets impacted by use of

AW products ?

Are there other factors that should beconsidered ?

7/23/2019 fs11-1320345716-87219


Specifying AW Products

For Heavy Use and Durability; Longer Life;Highest Performance Levels…

They typically Cost More…

Drawback: Aesthetics and other Featuresthe end user may object to…

Advantage: “Green” – Aluminum has

Recycle Capabilities

“Structural” vs. “Energy”

“Commercial” vs. “Residential”

Separate and Distinct Criteria

Carefully Weigh the aspects and howthey relate to the Specific Project Needs

“Longevity and Performance” vs.“Incentives”

What Criteria for Energy ?

NFRC 100 (U Value) 200 (SHGC) vs AAMA 1503 Frame Material

What is „Test‟ size used in evaluation?

NFRC = 47x59 vs. AAMA =48x72

How many of that size on the building?

Glass Package:Low E – Hard Coat or Soft Coat

Spacer – Standard or Warm EdgeAir or Gas Filled (Argon/Krypton -
