2 Topics covered 1. Primary and Secondary Designator Review 2. NAFS Testing Requirements for Mullions 3. NAFS Labeling Guidelines Phase 2

3 1. Primary and Secondary Designator Review

4 PG New concept in NAFS: Performance Grade

5 PG New concept in NAFS: Performance Grade

6 PG New concept in NAFS: Performance Grade

7 New concept in NAFS: Performance Grade B-rating C-rating PG A-rating Air Leakage Test (Pass/Fail)

8 Performance Grade In the USA, Performance Grade is all you need to describe air-water-structural product performance In Canada, we have always specified these properties separately from one another We determine PG and Water Test Pressure using the Canadian Supplement We select air leakage levels from the Canadian tables in NAFS and the Canadian Supplement

9 Water Test Pressure separate from Performance Grade C-rating B-rating PG By definition PG has a default water test pressure: 15% DP

10 Water Test Pressure separate from Performance Grade C-rating B-rating PG By definition PG has a default water test pressure: 15% DP for R, LC, CW

11 Water Test Pressure separate from Performance Grade C-rating B-rating PG By definition PG has default water test pressure of 20% DP for AW Class

12 Choose Performance Grade on basis of design pressure

13 Choose Performance Grade on basis of design pressure PG Specify: PG 30, Water test pressure 220 Pa

14 Choose Performance Grade on basis of design pressure

15 Choose Performance Grade on basis of design pressure PG Specify: PG 30, Water test pressure 290 Pa

16 NAFS Primary Designator Primary Designator: Performance Class, Performance Grade and size tested Example Fixed Window (IP): Class R PG 15: Size tested 48 x 48 in Class LC PG 25: Size tested 56 x 56 in FW* Class CW PG 30: Size tested 60 x 60 in Type FW* Class AW PG 40: Size tested 60 x 99 in Fi xed* The primary designator is sufficient to describe product performance in the U.S. (Combines ABC ratings) * Addition of product type to primary designator is optional

17 NAFS Primary Designator (Metric) Primary Designator: Performance Class, Performance Grade and size tested Example Fixed Window (metric): Class R PG 720(metric): Size tested 1200 x 1200 mm Class LC PG 1200(metric): Size tested 1400 x 1400 mm FW* Class CW PG 1680(metric): Size tested 1500 x 1500 mm Type FW* Class AW PG 1920(metric): Size tested 1500 x 2500 mm Fi xed* * Addition of product type to primary designator is optional

18 NAFS product types

19 NAFS product types illustrated

20 NAFS Secondary Designator Secondary Designator: a multiline listing of Canadian performance attributes Positive Design Pressure Negative Design Pressure Water Penetration Resistance Test Pressure Canadian Air Infiltration/ Exfiltration Level 1200 Pa 1440 Pa 220 Pa A secondary designator is mandatory in Canada, but is optional in the US Allows us to specify air and water separately from design pressure in the Performance Grade Secondary designator must be used with a primary designator, never on its own A3

21 Canadian NAFS labeling requirements Manufacturer name series/model of product Primary Class CW PG30: Size Tested 800 x 1500 mm Type C Positive Design Pressure (DP) 2400 Pa Secondary Negative Design Pressure (DP) Water Penetration Resistance Test Pressure Canadian Air Infiltration/Exfiltration 2400 Pa 360 Pa A3 Level Conforms to AAMA/WDMA/CSA 101/I.S.2/A and CSA A440S1-09 Both primary and secondary designators must appear on Canadian NAFS performance labels

22 Canadian NAFS labeling requirements Manufacturer name series/model of product Class CW PG30: Size Tested 800 x 1500 mm Type C Positive Design Pressure (DP) 2400 Pa Negative Design Pressure (DP) Water Penetration Resistance Test Pressure Canadian Air Infiltration/Exfiltration 2400 Pa 360 Pa A3 Level Conforms to AAMA/WDMA/CSA 101/I.S.2/A and CSA A440S1-09 No CSA, AAMA or other certification marks permitted unless products are CERTIFIED by those bodies!

23 Canadian NAFS labeling guidelines Phase 1 Guidelines released in November 2013 Illustrate label variations and options Phase 2 Guidelines Mulled Products underway

24 2. NAFS Testing Requirements for Products with Mullions

25 NAFS-08 vs. CSA A CSA A440 ratings applied to products up to 25% larger than tested size CSA A Tested size

26 NAFS-08 vs. CSA A CSA A440 ratings applied to sizes up to 25% larger than tested size NAFS and Canadian Supplement ratings apply only to tested size or smaller CSA A Tested size NAFS-08

27 NAFS-08 vs. CSA A CSA A440-00: mullion testing requirements were not clear Most manufacturers, certifiers ignored mullions, tested single operators only

28 NAFS-08 vs. CSA A Single operator labels were applied to untested mullion configurations C A F F A C F F F C F Typical untested products

29 NAFS-08 vs. CSA A Single operator labels were applied to untested mullion configurations and DO NOT represent product performance C A F F A C F F F C F Typical untested products

30 NAFS-08 vs. CSA A Mullions increase crack length affecting air and water leakage

31 NAFS-08 vs. CSA A Mullions carry most of the wind load from glass Loads transferred to frames at joints, affect anchoring `

32 NAFS-08 vs. CSA A To rate the performance of products with mullions, you need to test the performance of products with mullions

33 NAFS requires lab testing to rate performance To rate the performance of products with mullions, you need to test the performance of products with mullions Mullion performance can not be ignored under NAFS

34 Products with mullions NAFS defines two kinds of products with mullions: Composite Unit products Combination Assembly products Different testing, rating, and labeling practices for each

35 NAFS-08 and mullions Composite Unit products Composite unit: two or more sashes, leaves, lites, or sliding panels within a single frame and utilizing integral mullions must be tested as one unit

36 NAFS-08 and mullions Composite Unit products

37 NAFS-08 and mullions Composite Unit products Composite units shall be tested as a complete unit... further division of composite units for testing as sub-units shall not be permitted

38 NAFS-08 and mullions Composite Unit products Composite units shall be tested as a complete unit... further division of composite units for testing as sub-units shall not be permitted Ea ch unique intermediate framing member in a composite unit shall be tested in the longest dimension for which compliance is desired. Intermediate framing members which are longer or which are not tested shall not comply. Fra ming members shall be of identical cross-section to those tested to claim compliance.

Intermediate framing members which are longer or which are not tested shall not comply. Fra ming members shall be of identical cross-section to those tested to claim compliance.

41 NAFS and mullions Composite Unit products NAFS allows testing of combination units to qualify the different operator types within them A single test can give you ratings for several product configurations, but not the other way around

42 NAFS-08 and mullions Combination Assembly Products Combination assembly: two or more separate fenestration products joined together (combination / reinforcing mullions) Can test as an assembly, or test individual units separately Mullion ratings may be determined by licensed professional engineer using AAMA 450

43 Combination mullion

44 Reinforcing mullion

45 Combination Assembly: multiple labels, single valid rating When tested as separate components, can have separate labels for each of the mulled components, including the mullion connector. The Overall performance rating is determined by the lowest Performance Class, Performance Grade, water test pressure, and greatest air leakage level of the individual units and mullions (Worst air) (Worst water) (Worst structural) PG 30 PG 25 PG 20 PG 20

46 Review NAFS-08 and products with mullions 1. Cannot ignore mullions when rating performance 2. NAFS distinguishes Composite Units from Combination Assemblies, has different testing requirements for each Combination Assembly Composite Unit

47 3. NAFS Phase 2 Labeling Guidelines

48 Process Working group of Canadian and US manufacturers, Fenestration Canada, WDMA and AAMA Numerous conference calls and document drafts Goal: labeling guidelines that are based on NAFS defined testing/ engineering procedures, and performance reported with Primary and Secondary designators Timeline: Working group reported to Technical Committee today Technical Committee to review and comment by end of June Issue document by Aug. 1

49 Combination Assembly products Combination Assembly performance can be qualified in several ways: By testing the Combination Assembly (air-water-structural) By testing Mullion Assemblies for air and water, and rating the Mullions using AAMA 450 methods Four labeling options for Combination Assembly products to address needs of fabricators and existing certification programs

50 Combination Assembly products Example window for Combination Assembly labels 2750 mm 1525 mm

51 Combination Assembly products Test Data for Example window for Combination Assembly labels Overall rating is: Class R PG30, 220 Pa water, A2

52 Combination Assembly Label Options Label option 1 Single Label Reporting Overall Rating Performance

53 Combination Assembly Label Options Label option 2 Separate Product Performance La b e ls

54 Combination Assembly Label Options Label Option 3 Single Label Reporting Individual Component Ratings

55 Combination Assembly Label Options Label Option 3 Single Label Reporting Individual Component Ratings

56 Combination Assembly Label Options Label Option 4 Separate Product Performance Labels that Include Overall Product Performance

57 Composite Unit Products Single label reports performance ratings Ratings based on testing and optional use of engineering based on AAMA 2502 or WDMA I.S. 11 Example Label reports overall product performance

58 Use of engineering NAFS allows limited application of engineering to reduce testing using standards referenced within NAFS-08 AAMA 2502 describes use of Comparative Analysis WDMA I.S.11 describes use of Comparative Analysis and Extrapolative Analysis AAMA 450 describes use of engineering to qualify structural performance of combination/reinforcing mullions Technical committee proposes recommendation to allow latest versions to be used Will request JDMG to amend NAFS-08 to allow latest versions to be used

59 Use of engineering Engineering documents referenced by NAFS-08 are superseded by newer versions
