20. Woodwork Solutions “Using Substrates, Veneers, Overlays, and Panel Products” Architectural Woodwork Institute

21. Agenda Cores and Substrates What is “plywood” anyway? Particleboard, Fiberboard, Veneer, Combo. Facing Materials Wood Veneers High Pressure Decorative Laminates Overlays, films, papers, foils, etc. Panel Standards

22. Types of Panel Cores - Pg 36 45 lb. Medium Density Industrial Particleboard Best under HPDL—OK under Veneers Only Fire-rated product for paneling 45 lb. Medium Density Fiberboard (MDF) Best under Veneers Good for “paint”

23. Fire Retardant Core Not for furniture Class I or A for paneling attached to walls

24. Core Performance Table 200-G-3 — Page 37 Flatness vs. Stability 45 Lb. PB and MDF Veneer Core

25. What is “plywood”? “Three or more layers of wood or wood products laminated into a single sheet.” Examples on Pages 38-39 Particleboard Core Plywood Fiberboard Core Plywood Veneer Core Plywood Panel Balance a Must! Combination Cores

26. Facing Materials Wood Veneers High Performance Overlays High Pressure Decorative Laminate (HPDL) Thermoset Decorative Overlay Other Overlays (“melamine”) Vinyl Films Papers and Foils

27. The Big Five Wood Veneer Panel Specifications Species Cut “Match” between leaves “Match” within a single panel face “Match” in a room: panel-to-panel Apologies for the use of “Match” 5

28. Wood Veneer Species Section 200 - Panel Products - Page 42 Wood Veneer Species Table Samples Available “Live” Samples and Selected Flitch After the Species, Choose the “Cut” 1

29. Plain or Quartered or Rift? Plain (Flat) Slicing Wider Available Quarter Slicing Narrow striping “Flake” in Oaks Rift Slicing (Oaks) Narrow striping Minimized “Flake” 2

30. Plain Slicing Pg 43 - Cut across the growth rings Most common type of cut Cathedral pattern at the heart Straight pattern at the edges 2

31. Quarter Slicing Uses a quarter section of the log Cut perpendicular to the growth rings Narrow boards and leaves Stripe pattern - vary in width 2

32. Rift Slicing Most often in Oak - Rarely other species Veneers are lathe-sliced Even narrower leaves Stripe pattern - Avoids the decorative “flake” 2

33. Rotary Slicing Paper towels off a roll AWI Custom Grade AWI Economy Grade Not in Lumber Used for special effects Wild figure in most species 2

34. Btw Leaves - Book Matching Most common Leaves opened like a book Visual Effect Joints match Symmetrical pattern “Progression” Used with Plain Slicing most 3

35. Btw Leaves - Slip Matching Next most used Leaves “slipped” off in sequence without turning Visual Effect Repeating figure No grain match at joints Good for quartered and rift 3

36. Btw Leaves - Random Match Veneer book broken Leaf sequence destroyed on purpose Visual Effect Casual or rustic Appearance of boards More difficult than Book or Slip 3

37. Btw Leaves - End Matching Pg. 46 - Tall Systems or Short Veneer Architectural Vs. Panel End Match Visual Effect Extend apparent height of the wood Best used with BOOK Most complex 3

38. Single Face - Running Match Each face uses maximum yield Results in unequal widths Seldom “sequenced and numbered” sets Common Error Not related to room Not “best” for looks 4

39. Single Face - Balance Match Nominal uniform width Even or Odd number of leaves Pleasing appearance Most common Moderate cost 4

40. SF: Balance and Center Match Nominal uniform width Always even number of leaves either side of a center line Considered most pleasing by some Modest loss of figure due to clipping 4

41. Panel-to-Panel Matches Pre-manufactured Sets Page 50 - Warehoused Sets - Few Panels Pre-manufactured Sets - Reduced Page 51 - Recut into modular widths Sequenced Uniform Size Page 52 - Made to order - All same size Blueprint - The Prince of Panels 5

42. Made to Order - Made to Size Panels numbered in exact sequence Requires highly competent woodworker Requires careful site coordination Requires Long Lead Times Most Impressive Blueprint Matched Panels 5

43. The Big Five Revisited Wood Veneer Panel Specifications Choose the Species Specify the Cut Spec. Match between leaves Spec. Match within a single panel face Spec. Match in a room: panel-to-panel Fire Rated Panel Considerations Page 47 - Section 200-G-10 5

44. HPVA Veneer Face Grades Page 54 - Sections 200-S-6 & 7 Upper Three Grades from HPVA “AA” and “A” and “B” Defined in Words - Page 55 Defined in Tables - Pages 58-63 Separated by Species Groups/Hardwoods Selected Softwoods on Page 63

45. Compare HPDL and Overlay High Pressure Lam. Wear Cycles - 400 Stain No Effect - 1-10 Moderate - 11-15 Cleanability - 20 Impact HGS = 50 inches VGS = 20 inches • Thermoset Overlay • Wear Cycles - 400 • Stain • No Effect - 1-10 • Moderate - 11-15 • Cleanability - 20 • Impact - 15 inches

46. In this Module you … were exposed to the terms of the trade, learned about a variety of cores, explored wood veneers, got a checklist of the Big Five, grew in understanding panel standards, compared HPDL and Overlays.

47. Questions? Comments?

48. Factory Finishing, Section 1500 • How to use the book to specify top coats • A discussion about the sample submittal process. • Evaluating samples and the final product

49. Specifying with QS • Section 1500 is about factory finishes. • This section primarily deals with top coats. • No system numbers, only system names • Glossary of finishing terms on page 506 • Two groups: Standard Production Finishes and Specialty Finishes

50. Standard Production Finishes Usually available Suited to most uses Some old favorites Lacquers Acrylics Varnishes Specialty Finishes Availability varies May require special equipment and/or procedures to apply Generally add cost System Descriptions - 487 ƒƒ
