About WISA birch plywood

 

Birch plywood is known for its beauty and strength. It is ideal for interior design and furniture because of its harmonious and uniform surface appearance and dimensional accuracy. However, birch plywood’s superior strength and stiffness make it perfect for demanding industrial applications where bending is not allowed even under heavy loads, such as trailer floors and formwork. It also has the optimal balance between strength, weight and density making it the best choice for transport use where all three are important. WISA-Birch is also an ideal solution for LNG carriers with membrane type cargo containment systems.


WISA-Birch plywood products are made of one and the same wood from top to bottom with no other wood species used as raw material. This results in consistently high quality and reliable technical performance.

All WISA® plywood raw material is sourced from responsibly managed forests. It is a renewable, sustainable, safe and versatile material that helps reduce the carbon footprint of your project.

Benefits of WISA birch plywood’s
stiffness and durability

 

Benefits of the stiffness 

  • Birch plywood is strong and stiff.
  • It suits applications where bending is not allowed even under heavy loads.
  • WISA-Birch plywood is reliable and constant in its stiffness, density and thickness.
  • It is dimensionally accurate which makes it a good choice for demanding industrial applications such as concrete forming, vehicle flooring and LNG shipbuilding.

Benefits of  the durability

  • Birch plywood is very durable.

  • It withstands wear and tear and does not break easily.

  • Birch plywood is able to maintain its original dimensions even when the surrounding temperature conditions vary widely. In LNG ships the difference in temperature outside and inside is almost two hundred degrees Celsius.

  • It also has the optimal balance between strength, weight and density making it the best choice for transport use where all three are important.
 

Strong, reliable and visually pleasing WISA birch plywood, is the perfect material for concrete forming and elegant design



 

WISA birch plywood for formwork and casting

Wall formwork casting calls for excellent strength and load bearing properties in plywood. Birch-based panels are ideal for demanding castings because of their extraordinary stiffness.

WISA-Form plywood panels provide first-rate technical properties plus various coatings developed for different casting needs. WISA-Form birch plywood is a popular material for concrete moulds due to its strength. In demanding formwork and casting applications, film-coated birch plywood is highly durable and can be used for dozens of castings if properly maintained.

WISA birch plywood for vehicle flooring

Birch plywood is used as non-slip flooring material and as structural, assembly-ready plywood components in trailers, trucks, and other commercial vehicles. Plywood flooring often functions as a load-bearing element in the vehicles, so in addition to being strong, the material needs to be of a consistent and high quality. 

Birch plywood’s excellent strength-to-weight ratio means more payload and less fuel, making it a cost-effective and environmentally sound choice. The price-performance ratio is a also a significant factor as well as reliable deliveries that keep the fleets on the move.

WISA birch plywood surface grades

No plywood panels will look the same – that is the beauty of natural materials. 

 
 

Premium - WISA-Birch Premium

For surfaces to be lacquered

For a polished look, go for a WISA-Birch Premium. It is light and uniform with a face veneer made of one sheet. It is recommended for surfaces to be lacquered. Some healthy knots (diameter up to 12 mm) are permitted as is slight variation in colour. Does not contain plugs or surface joints.

 
 
 

S - WISA-Birch Special

For surfaces to be painted 

Recommended for surfaces to be painted with non-transparent paint. A good, uniform grade. Some sound knots (diameter up to 12 mm) and a limited number of other knots (diameter up to 8 mm) are permitted. Partial discolouration is permitted. Does not contain plugs or surface joints.

 
 
 

BB - WISA-Birch

For technical applications

A grade most used in technical application where sound surface is needed. Wooden plugs are used on surface veneer. In addition, minor surface defects are repaired with synthetic filler. A few sound knots (diameter up to 25 mm) and other knots (diameter up to 6 mm) are permitted.

 
 

WG - WISA-Birch

For constructional purposes

Suitable for constructional purposes where appearance is not important. Open splits, knot holes and other defects are permitted. WISA-Form birch plywood is a popular material for concrete moulds due to its strength. In demanding formwork and casting applications, film-coated birch plywood is highly durable and can be used for dozens of castings if properly maintained.
