Veneer[edit]

• veneer is always glued on both sides of a sheet (to keep the sheet stable)
• veneer thickness is 0.6mm, so basic sheet thickness always increases with 1.2mm when veneer is glued
• when veneer on second size is not specified, ocoume is used
• before glueing veneer the sheet can be sanded in order to reduce thickness, a sheet with a basic thickness of 15mm is after sanding and gleuing veneer maximum 15.5mm thick

Birch (BIR)[edit]

• density 600-700 kg/m3 - use 650 kg/m3 for calculations
• density with HPL (2x 0.75mm)
  • 15mm 761 kg/m3

Ocoume (OCO)[edit]

• density 500-550 kg/m3 - use 525 kg/m3 for calculations

Poplar (POP)[edit]

• density 400-450 kg/m3 - use 425 kg/m3 for calculations
• thickness 4-9-15-18mm
• sheetsize 3050x1250
• density with HPL (2x 0.75mm)
  • 4mm 818 kg/m3
  • 9mm 631 kg/m3
  • 15mm 556 kg/m3
  • 18mm 536 kg/m3

ShipConstructor[edit]

For a correct weigth estimation of plywood with HPL, the density must be given per thickness, for a calculation method see 11016\our files\11016-70-900 interior.xls. Naming in database will be:

• 3 letter abbreviation - for bare plywood example bare ocoume: OCO
• 3 letter abbreviation / upper score / 2 digit thickness of bare sheet - plywood + HPL (HPL is always on both sides of panel) example sheeted birch plywood of 9mm thickness: BIR-09
