Q

How is millwork better than finish carpentry?

A

Millwork is done under controlled factory conditions with machinery and finishing techniques that cannot be duplicated in the field. Finish carpentry is completed on the job site and is of a lesser degree of quality.

Flush Paneling

A

Paneling with a flat, smooth surface with the edges butted together or joined with a reveal, and is built up of thin wood veneers glued to backing panels of particleboard, plywood, or other panel products.

54
Q

What is the primary consideration to make when specifying paneling?

A

The veneer matching method

55
Q

What are the three methods of veneer matching?

A

Matching between adjacent veneer leaves, matching veneers within a panel, and matching panels within a room.

56
Q

What are the three ways to match adjacent veneer leaves?

A

Book matching, slip matching, random matching

57
Q

Book Matching

A

The most common method of veneer matching in which the veneers are sliced off the log and every other piece is turned over so that adjacent leaves form a symmetrical grain pattern.

58
Q

Slip Matching

A

Veneer matching where consecutive pieces are placed side by side and the same face sides are exposed.

59
Q

Random Matching

A

Veneer matching where veneers are placed in a random sequence, and veneers from different flitches may even be used.

60
Q

How are veneers installed?

A

Glued to rigid panels

61
Q

What is the second consideration when specifying paneling veneers?

A

The method of glueing veneers.

62
Q

What are the three methods of matching veneers within a panel when using bookmatched veneers?

A

Running Match, Balance Match, Center Match

63
Q

Running Match

A

Veneer matching that alternates bookmatched veneer pieces regardless of their width or how many pieces must be used to complete a panel. Any portion left over from the last leaf of one panel is used as the starting point for the next.

64
Q

Balance Match

A

Veneer matching that utilizes veneer pieces trimmed to equal widths in each panel.

65
Q

Center Match

A

Veneer matching that has an even number of veneer leaves of uniform width so that there is a veneer joint in the center of the panel.

66
Q

What are the three ways panels can be assembled within a room?

A

Warehouse Match, Sequence Match, & Blueprint Match

67
Q

Type of panel matching, which is the least expensive method. Premanufactured panels (usually 4’ x 8’ or 10’) are assembled from a single flitch that yields from six to twelve panels. They are field cut to fit around doors, windows, and other obstructions, resulting in some loss of grain continuity.

A

Warehouse Match

68
Q

Type of panel matching that uses panels of uniform width manufactured for a specific job and with the veneers arranged in a sequence. If some panels must be trimmed to fit around doors or other obstructions, there is a moderate loss of grain continuity.

A

Sequence Match

69
Q

Type of panel matching, which is the most expensive method, in which the panels are manufactured to precisely fit the room and line up with every obstruction so grain continuity is not interrupted. Veneers from the same flitch are matched over doors, cabinets, and other items covered with paneling.Blueprint Matching

A

Blueprint Matching

70
Q

What are the two ways paneling is hung on the wall?

A

Aluminum Z Clips or Wood Cleats (both allow wood to expand/contract)

71
Q

What does HPDL stand for

A

High Pressure Decorative Laminate - Thin sheet of material made by impregnating several layers of kraft paper with phenolic resins and overlaying the paper with a patterned or colored sheet and a layer of melamine resin. The entire assembly is placed in a hot press under high pressure where the various layers fuse.

72
Q

What are type types of panel substrates for laminate?

A

Particleboard, Medium-Density Fiberboard (MDF), Hardboard, Veneer Core

73
Q

What is the most commonly used laminate substrate?

A

45 lbm density particleboard - it is the most dimensionally stable, provides a smooth surface for laminating, has sufficient impact resistance, and provides enough strength for holding screws and for constructing panels and casework.

74
Q

What is MDF used for and how is it made?

A

Popular substrate for plastic laminate that is made by breaking down wood fibers into very fine fluff and then mixing them with glue and compressing the mixture under high pressure..

75
Q

Which panel substrate has a smoother surface, MDF or particleboard?

A

MDF - The smoother surface reduces the potential for telegraphing through the laminate and makes it suitable for gloss laminates.

76
Q

Which is more expensive, MDF or particleboard?

A

MDF

77
Q

Untreated ______ has the same fire rating as plywood.

A

MDF - however, special fire-resistant MDF is available.

78
Q

What panel substrate is dimensionally stable and does not crack, warp or cup, and allows routing and has a flawless paint finish?

A

MDF

79
Q

What are the problems with using hardboard as a laminate substrate?

A

Its smooth surface can sometimes cause bonding problems.

80
Q

What are the problems with using veneer core as a laminate substrate?

A

It is subject to warpage and other problems and is not recommended for interior applications.

81
Q

What is the most common laminate thickness?

A

0.050 inches - used for both horizontal and vertical applications.

82
Q

How thick is post-forming laminate?

A

0.040 inches - its manufactured so it can be heated and bent to a small radius.

83
Q

How thick is vertical use laminate?

A

0.028 inches - for vertical applications that receive less wear amd impact than horizontal surfaces do.

84
Q

What are some non-standard types of laminates?

A

Backing sheets, cabinet liners, fire-rated, chemical-resistant, static-dissipative, and metal-faced laminates.

85
Q

What must be done (and why) when plastic laminate is applied to large surfaces of paneling?

A

It must be balanced with a backing sheet to inhibit moisture absorbtion and to attain structural balance so the panel does not warp.

86
Q

Standing Trim

A

An item of fixed length, such as a door or window casing, that can be installed with a single length of wood.

87
Q

Running Trim

A

An item of continuing length, such as baseboard, chair rail, or cornice.

88
Q

What is the difference between “standing and running trim” and “wood molding”?

A

89
Q

Why is shrinking and swelling in millwork not as much of a problem as it is for site-built carpentry?

A

Because of the improved manufacturing methods available in the shop and the fact that solid stock and veneer can be dried or acclimated to a particular geographical region and its humidity.

A

To protect woodwork from moisture, chemicals, and contact, and to enhance the appearance of woodwork.

92
Q

Which is the prefered method of wood finishing, factory or field finished?

A

Factory, because the results are easier to control.

93
Q

What must be done to wood before finishing?

A

Sanded and filled as needed.

94
Q

A coating material with a high nitrocellulose content modified with resins and plasticizers dissolved in a volatile solvent..

A

Lacquer

Catalyzed lacquers contain an extra ingredient that speeds drying time and gives the finish additional hardness

Standard lacquers are easy to apply, easy to repair and are relatively low in cost. They DO NOT provide the chemical and wear resistance that some of the other finishes provide. Catalyzed lacquers for transparent finishes are more difficult to repair and refinish, but are more durable and resistant to chemicals.

95
Q

Consist of various types of resinous materials dissolved in one of several types of volatile liquids.

A

Varnish

Conversion varnish is produced with alkyd and urea formaldehyde resins. When a high solids content is specified, the finish becomes opaque

96
Q

A synthetic material that creates a very hard, durable finish. Although difficult to repair or refinish, this finish offers superior resistance to abrasion and to penetration or damage from water and many commercial and household chemicals.

A

Polyurethane

Opaque polyurethanes are available in sheets from dull satin to full gloss.

97
Q

Synthetic material that gives the HARDEST, MOST DURABLE FINISH POSSIBLE.

A

Polyesters

Opaque polyesters can be colored and are available only in a full gloss sheen. Like polyurethanes, polyester finishes are very difficult to repair or refinish outside the shop, but they create very durable finishes with as much as 80% of the hardness of glass.

98
Q

What are the types of opaque wood finishes?

A

Lacquer, Varnish, Polyurethane, and Polyester

99
Q

What are the only types of woods that opaque finishes should be used on?

104
Q

What finish can be used to create the LOOK of an oil finish?

A

Catalyzed Vinyl

105
Q

What are the most durable (and expensive) transparent wood finishes?

111
Q

What is the standard thickness for solid surfacing?

A

3/4” (however lower priced products of 1/2” are available)

112
Q

How are scratches, stains and dents treated on solid surfaces?

A

Sanded out or cleaned with a household abrasive cleanser.

113
Q

How are solid surfacing materials fabricated and installed?

A

Using normal woodworking tools. Edges can be routed. Seams are filled with a two-part epoxy or liquid form of the material.

114
Q

Most model codes regulate what wood materials?

A

Woodwork as wall or ceiling finish materials.

115
Q

Most model codes DO NOT regulate what wood materials?

A

Furniture, cabinets, or trim (picture molds, chair rails, baseboards, handrails, doors and window frames and similar decorative materials used in fixed applications), including cabinets attached to a structure. Nor do they apply to materials that are less than 0,036 in thick and are applied directly to the surfaces of walls or ceilings.

116
Q

Wall and ceiling finish, including wainscoting, paneling, or other finish, applied either structurally or for decoration, acoustical correction, surface insulation, or similar purposed.

A

Interior Finish

117
Q

Most wood species without flame-retardant treatement have flame-spread ratings less than _____ and some even have ratings less than ___. This makes them appropriate for rooms, enclosed spaces, and some corridors without any special considerations.

A

200 (Class C); 75 (Class B)

118
Q

Trims generally must have a minimum Class __ flame-spread rating, and combustible trim, EXCLUDING HANDRAILS and guardrails, CANNOT EXCEED ___ of the aggregate wall or ceiling area in which it is located.

A

C; 10%

119
Q

What is the strictest regulation on the used of woodwork as an interior finish?

A

When paneling is used on walls and ceilings. The paneling must meet the maximum flame-spread rating of the code based on OCCUPANCY and USE AREA.

120
Q

When can veneer less than 0.036 in thick with any flame-spread raing be used?

A

When the veneer is placed on fire-retardant treated materials, such as particleboard.

121
Q

How should laminate be applied to comply with flame-spread codes?

A

Laminate is not subject to regulation if it is less than 0.036 in thich, but it should be applied to a substrate (usually particleboard) that is fire-retardant treated. Laminate for vertical use is 0.028 in thick, so it does not have to be fire treated. When thicker laminate is used and the flame-spread rating is critical, fire-rated laminate can be used on a fire-retardant treated substrate with the appropriate adhesive.

122
Q

How should wood blocking comply with flame-spread codes?

A

Blocking on the outside of the partition on which paneling is applied should also be fire-retardant treated. Some codes require that blocking within the partition be fire-retardant treated.

123
Q
