SECTION 8Wall/Ceiling Surfacing and Partitionsintroductory informationINTRODUCTION:MATERIAL SELECTIONS:CONTRACT DOCUMENTS SHALL INCLUDE:Section 8 includes information on wood veneer,solid wood, stile and rail wood, decorativelaminate, solid surface and solid phenolic productsand their related parts.For OPAQUE finishes: Medium Density Fiberboard (MDF) issuggested for cost savings and an optimumpaintable surface.Species, Slicing and Matching of individual leavesare reviewed and governed by Section 4, SheetProducts (Note unless otherwise specified; plainsliced and bookmatch are the default standards).Quality assurance can be achieved by adherenceto the AWS and will provide the owner a qualityproduct at competitive pricing. Use of a qualifiedSponsor Member firm to provide your woodworkwill help ensure the manufacturer’s understandingof the quality level required. Illustrations in thisSection are not intended to be all inclusive. Otherengineered solutions are acceptable. In theabsence of specifications, methods fabricationshall be at the option of the manufacturer. Thedesign professional, by specifying compliance tothe AWS increases the probability of receiving theproduct quality expected. Medium Density Overlay (MDO) which may bemachined and detailed with little loss of qualitysurface characteristics, requires a seal coatprior to application of finish coats with no sheenlimitation. Species: There are numerous foreign anddomestic species available. Involve yourmanufacturer early in the design and selectionprocess.WALL and CEILING SURFACING:Includes wood veneered panels, solid wood,decorative plastic laminate, solid surface, solidphenolic panels and factory built framing forsurfacing.Contract documents, furnished by the designprofessional, shall clearly indicate or delineatematerial, fabrication, installation, and applicablebuilding code/regulation requirements.Shop drawings, engineering, listings and mockupsare the means by which the design intent isturned into reality. They shall indicate methodsof construction, exact material selections, graindirection(s), methods of attachment and joinery,and exact dimensions. They should also includethe manufacturer’s technical suggestions. Listings(schedules) are sometimes used to list core,edge and face materials, adhesives etc. when notincluded on the shop drawings. Mockups may bespecified for review as a full scale model showing,materials, joinery and finishes and are often usedas the project control sample. Medium Density Overlay (MDO) - Thisprovides a paintable surface for panels. Thethermosetting resin overlay is designed to takeand hold paint. Opaque finish sheens above 40Satin require special finishing procedures. Close Grain Hardwood - Although allowed,extra preparation may be required bythe finisher as there may be grain showthrough, split veneer joints, and other woodcharacteristics. Manufacturers’ option - Face materials aredetermined by the manufacturer.For TRANSPARENT finishes:Selection starts by looking at “hand samples,”pieces of veneer or lumber representing aparticular species, but not necessarily a particulartree or log. Wood is a natural material (unlikea manufactured product), which varies fromtree to tree in its color and texture. Rather thansimply choosing an appropriate wood for itscolor, consider the size and availability of thespecies. A species that grows in smaller diameter,with shorter logs, lends itself to furniture andsmaller projects, whereas an abundant speciesthat grows in large diameter lends itself more tolarger public spaces. Many projects have run intodifficulties because the species availability was notcompatible with the project’s needs. 2014 AWI AWMAC WI 2nd Edition, October 1, 2014 Slicing: Select either rotary, plain sliced, quartersliced, or (in the case of Oak only) rift sliced. Matching of individual leaves: Select eitherbook matched (most appropriate for plainsliced), slip matched (most appropriate forquartered and rift sliced), or random matched(for a rustic look, usually more expensive). Matching on each panel face: Select eitherrunning match, balance match, or balance andcenter match. Specify type of end matching fortall elevations. Sequence matching between full width premanufactured panel sets.8PRODUCT ADVISORY:Due to adverse reaction of some veneerslaminated to fire rated (FR), ultra low emittingformaldehyde (ULEF or NAUF), medium densityfiberboard MDF - causing discoloration of thewood veneer even months after installation, majorcore manufacturers have issued disclaimers in theuse of FR cores. They strongly suggest that use ofFR ULEF MDFand particleboard cores should bedone after testing compatibility of adhesives, woodveneer and cores. Any resulting discoloration withthe use of these cores may be exempt in theirwarranties. Use of FR ULEF cores should onlybe considered after consultation with the boardsupplier.Architectural Woodwork Standards195

SECTION 8Wall/Ceiling Surfacing and Partitionsintroductory informationPANEL SEQUENCING: Running Match (cannot be end matched) - Each panel face is assembled from as many veneer leaves as necessary. This often results in a nonsymmetrical appearance, with some veneer leaves of unequal width. Often the most economical method at the expense of aesthetics.RemaindersFIGURE: 8-001 Balance Match - Each panel face is assembled from veneer leaves of uniform width before edge trimming. Panels may contain an even (balance andcenter) or odd (balanced) number of leaves and may change from panel to panel within a sequenced set.81A1B1CBalance and Center Matched1DFIGURE: 8-0022A2B2C2DBalance MatchedFIGURE: 8-003196 Architectural Woodwork Standards 2014 AWI AWMAC WI 2nd Edition, October 1, 2014

SECTION 8Wall/Ceiling Surfacing and PartitionsSEQUENCING of PANELS WITHIN A ROOMintroductory information(continued): PREMANUFACTURED SEQUENCED SETSFull width utilization is composed of a specific quantity of sequenced and numbered panels based on a per room basis for net footage selected fromavailable inventory. They are usually only available in 48” x 96” or 120” (1219 mm x 2438 mm or 3048 mm) sheets in sets varying from 6-12 panels. If morethan one set is required, sequencing between sets cannot be expected. Similarly, doors or components cannot be fabricated from the same set.
