Learning Objectives At 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 key

performance attributes

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

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

other 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)

AAMA/WDMA/CSA

101/I.S.2/A440-08

North American Fenestration Standard/Specification

for windows, doors, and unit skylights

Jointly published by AAMA, WDMA, and CSA

AAMA – American Architectural Manufacturers Association

WDMA – Window & Door Manufacturers Association

CSA – Canadian Standards Association

Test Reports

At least once every four years,

the manufacturer must retest the product to

verify that the design continues to comply with

the standard’s requirements.

97 05

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 public buildings, and facilities where heavy use is expected. Also, commonly used on other buildings with increased loading requirements. Architectural Window/AW: Typically larger institutional or

high-rise / mid-rise buildings to meet increased loading requirements, and buildings where possible misuse of the fenestration 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 and

other buildings where larger sizes and higher loading requirements are

expected.

AW: Commonly used in mid-rise and high-rise buildings to meet

increased loading requirements and limits on deflection, and in buildings

where frequent and extreme use of the fenestration products is

expected.

CW: Commonly used in low-rise and mid-rise buildings where larger sizes,

higher loading requirements, limits on deflection, and heavy use

are expected.

Evolution of standards… Test size requirements

AAMA 440-

Hung R Class test size: 40” x 63”

Hung LC Class test size: 44” x 75”

Hung C Class test size: 56” x 91”

Hung HC Class test size: 60” X 99”

Hung AW Class test size: 60” X 99”

AAMA ‘08 (New) AW (L/175) CW (L/175) LC R

*Listed in order of performance

Uniform Load Deflection Test

CW or AW Product

L/175:

Where L is Length of the weakest rail

divided by 175 = Maximum deflection.

Example:

48”/175 = to a maximum of 0.27” (.56%)

Product Designation System: Previous

Product Designation System: Previous

Product Designation System: New ‟08 Format

CW-PG50-H

CW = Product performance class (CW took the place of C and HC)

PG50 = Performance grade 50, designates Design Pressure (DP) of 50

H = Product type is hung window

Main Aspects of Testing (’08)

Air Infiltration : ASTM E 283

Water Penetration:

• ASTM E 331 – AW products

• ASTM E 547 - R, LC and CW products

Uniform Structural: ASTM E 330

Operating Force: ASTM E 2068

AW, CW, LC & R Comparison of Requirements

* The '05 C rating has been eliminated from this comparison.

* Per AAMA 502, field water pressure is

allowable at 2/3 of design pressure.

R, LC, CW & AW Comparison: Uniform Structural

R, LC, CW & AW Comparison: Other Requirements

Source: AAMA

AAMA 502

AAMA 502 refers to field testing of

fenestration products and allowable

performance values.

Air Infiltration: Field air infiltration is

permitted to be 1.5 times design values.

Water Penetration: Field water pressure is

allowable at 2/3 of design pressure.

Life Cycle Testing

Life Cycle Testing

Required on AW – the most significant difference versus CW product

“To model through…actual performance”

Equivalent to 7 years of everyday use.

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, Water

Penetration testing & Operating Force.

Life Cycle Testing Required for AW

(optional for other classes)

Vent Cycling Testing:

Operating ( 2,500 cycles )

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

* 5 cycles of Misuse and Abuse

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

Performance Testing

After Life Cycle Testing Required 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 be

considered ?

Specifying AW Products

For Heavy Use and Durability; Longer Life;

Highest Performance Levels…

They typically Cost More…

Drawback: Aesthetics and other Features

Separate and Distinct Criteria

Carefully Weigh the aspects and how

they relate to the Specific Project Needs

What is „Test‟ size used in evaluation?

NFRC = 47x59 vs. AAMA =48x72

How many of that size on the building?
