Plyroof

Description and Purpose

Ecoply structural plywood is a strong, durable panel manufactured from plantation grown Radiata pine veneers bonded with phenolic adhesive (WBP Type A marine bond). Ecoply is available in a range of thicknesses suitable for use as a substrate for decking and roofing for residential, commercial and industrial buildings such as houses, hostels, hotels, offices and factories.

• Plyroof has machine grooved long edges with a blue plastic tongue to form a tongue and groove joint between sheets to reduce nogging.
• Plyroof has unfilled unsanded D grade face and back with a rougher surface for extra strength and grip suited to shingle or tile applications on steeper roofs.

Advantages:

Superior Strength

• Strength properties are published in engineering codes. Ecoply Plyroof can be designed for high wind suction and high load performance for commercial use.
• Sheet diaphragm bracing capacity to resist lateral wind and earthquake loads.
• Strong substrate for staples and fasteners under a wide range of roofing tile systems.
• Smooth surface for membrane roofing.
• Range of thicknesses to suit many timber or steel frame spacings, flat or curved.

Superior Durability

• Full exterior phenolic marine type bond.
• H3 treatment available for high moisture exposure. Minimizes decay risk from:
  • solar driven or condensation moisture
  • long construction periods
  • high humidity industrial or swimming pool environments.

Subject to the limitations and conditions in this brochure, Plyroof, Plyfloor and Ecoply structural plywoods meet the requirements of the New Zealand Building Code Section B1 Structure, and B2.3(a) Durability and the Building Code of Australia 2007.
