-icause of its ability to resist racking hen properly nailed, Miller Redwood ywood requires no diagonal bracing hen applied to one 8-foot or two foot wall sections. For shear values in dwood plywood shear wall construc)n, see the American Plywood ;sociation s publication, Panel Wall )nstruction.

Flamespread ratings established by Underwrite/s Laboratories, Inc., are 75 for S/8-inch untreated redwood plywood, meeting Class ll standards under the UBC and Basic Building Code. Products 3/8-inch thick meet Class lll ?5225) standards, respectively. Special exterior fire retardant treatment is available to reach a Class I UBC and BBC rating.

Insulation value of Redwood plywood: (minimum ratings) K=0.98; R(3/8-inch) =0.45; R(5/8-inch)=0.75. Redwood plywood 5/8-inch thick insulates as well as 21/zinches of plaster,3 inches of clay tile,4 inches of glass, 872 inches of concrete, or 9 inches of stucco. A frame wall with redwood plywood interior paneling and exterior siding has about half the heat loss of lath and plaster finish on an 8-inch cement block or 1-inch stucco wall.

Specifying Miller Redwood Plywood: Grades, Composition

Miller Redwood Plywood's intended use, veneer grade, pattern, size and factory finish should be included in spee ifications. For example: "Exterior siding sha// use heartwood face veneers. with inverted batten pattern grooved 12 inches on center with shiplap edge. Size: 5/8-inch thick, 48-3/8 inches wide, and 9 feet long. Each panel shall be factory finished with water repellent, and identified with an American Plywood Associati o n g rade t rade m ark."

Miller Redwood Plywood is manufactured with a shadowy saw-textured surface that enhances its natural woodgrains and tones. Heartwood and sapwood-containing face veneers produce several grades that offer specifiers a range in appearance and price. Our top quality grade is identified by the proprietary name "Miller Premium Saw-Textured". Face veneers are entirely redwood heartwood, reddish brown to cinnamon in color, with superior decay and insect resistance from natural heartwood extractives. Veneers are reasonably matched when more than one is used per panel. No knots, knotholes or open splits are allowed. Solid pin knots up to 3/8-inch are allowed, along with shims and router or sled patches reasonably matched for grain and color. Wood patches are limited to panel edges and ends, with only occasional patches allowed in the face.

Our economy grade is "Miller Select Saw-Textured". Face veneers containing sapwood offer a rustic, varied appearance ideal for many building styles. Miller Select Saw-Textured does not contain knots, knotholes or open splits. Router or sled patches, and pin knots up to 3/8-inch are allowed, as are synthetic-filled knotholes and synthetic shims.

Composition of panels includes crossbanding inner plies that are redwood or another species at mill option. Center and back plies are redwood. Bonding is with fully waterproof exterior glue. Standard orders of redwood plywood are factory-coated with water repellent.

Panel dimensions are 8. 9 or 1O feet long, and 3/8-inch thick for three plies, or 5/8-inch thick for five plies. Panels with square edges are 48 inches wide while shiplapedge panels are 48-3/8 inches, lapped so that net coverage is 48 inches.

Panel patterns include T1-1 't grooved 4" or 8" o.c., inverted batten grooved 12" o.c. and plain faces to which battens can be applied.

Handling and I nstallation

On-site storage should be off the ground, in a cool dry place and out of the sun, and under a covering that's waterproof but allows air to circulate. Packing bands should be removed upon delivery.

Before construction, panel edges, including cut edges, should be sealed with final finish or topcoat materials other than paint For a stain or water repellent topcoat, water repellent should be brushed generously on both blind and exposed panel edges, and particularly lower drip edges of horizontaljoints. For a paint topcoat, edges should be sealed with paint primer. Vapor barriers applied to the interior or warm side of stud walls can increase the life of exterior plywood finishes and help avoid moisture build-up in stud cavities from extreme climate conditions. Building paper is required only where square panel edges are nailed directly to studs and not covered with battens. Caulking is required at inside and outside corners, and at square panel edges.

Non-corrosive nails. Top quality, hot-dipped galvanized, stainless steel or aluminum nails should always be used on redwood plywood siding and interior paneling near moisture. We do not recommend the use of common iron, copper, cement-coated or electroplated nails. For strongest nail-holding on exterior siding, spiral-grooved or annular ring shanked anchoring nailsnot casing or finishing nails-should be used, driven flush, not set.

For 3/8-inch plywood siding, 6-penny siding or box nails should be used, and 8-penny for 5/8-inch panels. lf plywood is applied over composition, pressed fiber, insulation board or gypsum board sheathing, the next larger nail size is needed to penetrate at least 172 inches into solid wood. For interiors,4- or 6-penny casing or finishing nails should penetrate at least 3/4-inch into solid wood.

Stud spacing for all vertical siding applications without sheathing must be no more than 16 inches on center. HUD standards also require stud spacing no greater than 16 inches on center for T1 -11 patterns grooved 4 and 8 inches on center. (Check local building codes for variations.) All panel edges and joints require solid backing of studs or blocking.

Studs may be 24 inches on center for all vertical siding with sheathing;

Miller Redwood Plywood Profiles

Miller Saw-textured Redwood Plywood is available in the following standard sizes and patterns (all available in lengths of 8, 9, and ln vertical exterior applications of square-edge plywood, a 1/8-inch gap should be left between panels. The ga may be caulked or battened, with the batten nailed thr6ugh each side in a staggered pattern, at least '1 inch into solid wood studs. For 3/8- and S/8-incl plywood, grooved, shiplapped or with wide inverted battens, a 1/1 6-inch gap should be left between paneledges. For horizontal joints, galvanized or aluminum flashing should be installed with at least 1/8-inch left between it and the panel above. liller Redwood Plywood on commercial uildings.

S/8-inch panels in plain or inverted batten patterns grooved 12 inches on center; all horizontal applications with horizontal joints blocked; and all interir paneling. Over interior masonry walls, 1x2 furring strips should support all edges and joints.

Panel spacing and nailing of Miller Redwood Plywood, as with all natural materials, must allow for some expansion and contraction to avoid buckling. In addition, as with all wood siding, a 6 inch minimum clearance should be allowed between redwood plywood sic ing and the ground.

For interior paneling applications, a ga1 of 1/32-inch should be left on plywood ends and edges.

Nail spacing for interior and exterior applications: 3/8-inch in from panel edges, every 6 inches along joints and edges, and every 12 inches at intermediate supports.

rinishes, Maintenance, ixterior Finishes

rliller Redwood Plywood's saw-textured urface, open cellular structure and lack rf pitch or resins assure outstanding renetration and retention of a wide ariety of finishes. Miller Redwood )lywood is shipped with a factoryrpplied water repellent, allowing it to reather slowly to buckskin tan and rventually to warm gray. Coatings lescribed here can modify weathering, rrovide some protection from dirt and noisture, and allow unlimited color rffects for maximum design versatility tnd endurance. br best penetration, coatings should re brushed on with a nylon or natural rristle brush, or special long-nap roller. ipray application doesn't cover sawextured surfaces evenly, although cpcoats can be sprayed on over brushrpplied basecoats. Back-brushing nmediately after spray application rproves penetration. tdditional water repellent can be rrushed on over factory-applied coatings r prolong Miller Redwood Plywood's ruckskin tan color. lt should be first pplied 6 months to a year after plywood i installed, and should contain a mildewcide. Reapplication is called for if redwood heartwood extractive stains appear, or when surfaces bleach gray and don't bead water.

Miller Redwood Plryood as an interior accent. Redwood plywood can give an added dimension to living areas. Shown here: 5/8" Miller Select Saw-Textured T 1-'l 1 with grooves 8" o.c.

Stains can be applied to match or contrast with other structures, ground coverings or natural surroundings. They range from semi-transparent penetrating coatings that provide enduring color without obscuring woodgrain patterns, to heavily-pigmented stains that show off saw-textu red su rfaces.

Paint provides maximum color variation on redwood plywood, and is particularly effective for traditional building styles or accent walls. Latex topcoats should be applied over oiFbased primer that prevents extractive bleeding. Shake-andshingle paints or low-luster alkyd topcoats that absorb water and maY react with heartwood extractives are not recommended.

Varnishes and other clear film-forming finishes should never be used as they tend to yellow, crack and peel after minimum exposure to weather. They are also extremely difficult to refinish. To restore natural colors, sudaces can be scrubbed using a stiff bristle brush and a solution of 1 cup trisodium phosphate per gallon of warm water, then rinsed with clear water. This should be followed with a solution of 4 ounces of oxalic acid crystals dissolved in 1 gallon of warm water, applied with a soft brush. Wood surfaces should be allowed to dry, and then be rinsed with clear water.

To treat mildew, heavy extractive staining or severe weathering, surfaces should be scrubbed with a solution of 1 cup trisodium phosphate plus 1 cup of household bleach in 1 gallon of water. Rinse with water, apply the oxalic acid solution used above, and allow wood to dry throughly. Rinse again with water and allow it to dry. Finally, water repellent containing mildewcide can be applied to prevent further problems.

lnterior Finishes

Redwood plywood interior paneling should be sealed on faces and edges with two coats of an alkyd-resin base penetrating sealer. Applied directly to wood surfaces or over a coat of penetrating stain, sealer prevents vaporizing of factory-applied water repellent. In kitchens and bathrooms, additional coats of sealer are recommended for easy cleaning.
