PLYgroove®

PLYgroove is suitable for a range of applications including internal lining, ceiling lining, feature walls, back lining to exposed rafters, commercial interiors, soffits & furniture.

PLYgroove combines the strength of plywood with a decorative attractive grooved finish. Manufactured from FSC certified Plywood the panels are impact resistant and hard-wearing.

PLYgroove is easy to install as lightweight and no special tools are required.

Compliance

PLYgroove is manufactured to comply with AS/NZS 2269.0:2008.

PLYgroove can be used in compliance with the Building Code of Australia as follows:

• Structure

  PLYgroove is structural plywood which is the only wood based panel material with design values in the timber engineering codes in both Australia and New Zealand. PLYgroove complies with the requirements of NZS 3604 and may be used in accordance with AS 1684.

• Durability

  Plygroove will last in excess of 50 years in dry interior spaces. In wet areas like kitchens, bathrooms or laundries, Plygroove should be protected from water splash by good quality paints or coatings. Attack from, common household borer is unlikely or will be at an acceptably low level provided the plywood is kept dry. For termite protection, design and maintain in accordance with AS 3660. For exposed situations Plygroove requires proper treatment to MP3640 or AS 1604.

• Moisture

  PLYgroove is supplied at the correct moisture content for interior use. It should be protected from dampness throughout delivery, storage on site, and during construction.

• Fire

  PLYgroove has been tested for Early Fire Hazard properties. It can be used in any occupancy when the surface finish on the plywood has an index below that required.

  Early Fire Hazard Properties of 12mm thick Plygroove Plywood

  Coating	Ignitability Index: 1g	Spread of flame Index: SFI	Heat Evolved Index: HEI	Smoke Developed Index: SDI
  Untreated, uncoated	14	7	7	3
  Intumescent * coating	5 to 12	0	0 to 3	4 to 5

  Note: * Intumescent coatings are available in clear and pigmented versions from Firepro Safety Ltd (Nullfire WD, Flamecoat) and Polymer Development Group Ltd (Unitherm 19010)

• Thermal Insulation

  Plywood has a thermal conductivity of 0.13 W/mK and adds 0.1 to the R value of wall or roof assemblies. In design consider the whole assembly including enclosed air and insulation.

Installation

Framing

Framing centres are in Table 3. All edges of 7 mm PLYgroove should be supported. The Tongue & Groove joint on 12 mm sheets does not need support - all other edges do.

Maximum frame centres (mm):

Closer spacings are recommended in high impact areas e.g. bars, gyms, industrial or crowded spaces. In damp situations, allowance should be made for swelling.

Fixings

Nails: Use 40 x 2.0 mm panel pins at 150 mm centres at sheet edges and 300 mm centres on intermediate supports. If back nailing over rafters use 40 mm x 2.5 galvanised flat head nails.

Screws: Use No.8 gauge x 40 mm screws on timber framing and 10- 16-45 self drilling self tapping screws on steel. Select screw head to suit architectural details.

Adhesives: Panels may be fixed with a bead of elastomeric construction adhesive .either by nailing at 150 mm centres on all glued surfaces, or by applying pressure and cure time in accordance with the glue manufacturers instructions. Use glues to American Plywood Association Specification AFG 01. (e.g. Max Bond, Sturdi Bond, Nortons Floormate).

PLYgroove as bracing

Flathead nails are normally required for bracing and may be used as a decorative feature (eg rosehead stainless steel annular grooved), or hidden beneath mouldings, skirtings, etc. Ecoply 7 mm plywood has been tested with elastomeric glue. Use bracing ratings in accordance with the Plybrace House Bracing System Manual when PLYgroove is fixed with standard flathead nails, or 40 mm bullet head nails with elastomeric adhesive to AFG01. For Australian applications where the panel is being used for wind resistance only, use resistance values and fastenings as given in the PM "Featuring Plywood in Buildings" brochure. PLYgroove fixed with panel pins or bullet head nails only is rated for a reduced wind bracing value, but is not suitable for seismic bracing. 12 mm T & G PLYgroove must be fixed to framing along the tongued edges for bracing. For further bracing information refer to Plybrace: House bracing system manual.

Finishes

Punch nails before finishing and apply a first coat (clear, primer or sealer) before filling punched holes to minimise dryout or staining. High quality paints, stains or clear finishes are recommended for PLYgroove. Tinted clear finishes can provide a full range of architectural options that show the warmth of wood, while reducing yellowing and other ultraviolet effects. The use of high gloss finishes and paints tend to highlight naturally occurring and manufacturing characteristics of plywood such as changes in grain and beat marks from the sanding. Matt finishes and paints are recommended to provide a natural timber finish. PLYgroove is a wood based product that responds to changes in humidity. Avoid using inflexible coatings (such as epoxies) that my check on movement of the wood. For ceilings or similar applications it is an advantage to prefinish panels prior to installation. Use the coating manufacturers specifications.

Soffit linings

PLYgroove can be used to line under the eaves of buildings. Good quality paint or stain is recommended to protect the untreated plywood from intermittent wetting and wind blown moisture. If the Soffit is very exposed or in large overhangs, preservative treatment should be considered. Do not use water based treatments on PLYgroove.

Storage and handling

• Keep dry.
• Store under cover (avoid tight cover and potential condensation).
• Handle and stack with care to avoid damage.
• Handle and stack with care to avoid damage.

Supply

Available from stockists, merchants and agents throughout Australia, New Zealand, Pacific Islands and some Asian countries.

Limitations

All statements in this manual shall be read subject to the plywood being properly stored, handled, installed, used and maintained as appropriate to each application in accordance with this brochure, and subject to the governing codes of practice.

Formaldehyde Emissions

All PLYgroove is manufactured using an ‘A’ Bond with less than 0.3mg/l Formaldehyde (equivalent to Super E0) emissions from the final product. Click here for formaldehyde certificate.
