Koskisen 1.5mm Birch or Combi Plywood is a thin, lightweight plywood sheet manufactured in Finland by Koskisen Oy. Designed for non-structural internal applications, this flexible panel is ideal where a smooth, stable facing or lining material is required.

The product is manufactured and assessed in accordance with EN 13986:2004 + A1:2015 and uses an exterior-grade bonding system, providing excellent ply integrity despite its thin profile.

Standards & Classification

• Plywood type: Birch or Combi plywood
• Thickness: 1.5mm
• Harmonised standard: EN 13986:2004 + A1:2015
• Bonding quality: Class 3 (Exterior)
• Formaldehyde emission: E1

Due to its thickness, this product is not suitable for structural use, regardless of glue class.

Glue Line & Bonding

• Manufactured using a phenol formaldehyde (WBP) glue line
• Bonding Class 3 (Exterior) under EN standards
• Provides strong resistance to delamination and moisture at the ply bond level

While the glue line is exterior-rated, the sheet thickness limits end use to non-structural applications.
