Sveza Birchply is high quality light weight multi layered plywood panel made throughout from machine composed birch veneers and faced with a natural whole piece birch veneer of 1.4mm thickness. It is bonded with thermosetting, exterior quality phenolic resin adhesives commonly known as WBP (Weather and Boil Proof) and is compliant California ARB regulations on formaldehyde emissions. It also complies with European E1 standard.

Sveza Birchply™ Birch Plywood is ultimate in Plywood having excellent physical and mechanical properties. It can be laser cut and also CNC machined owing to its uniform construction.

Sveza Birchply™ Birch Plywood has been designed to suit any and every application where durability, versatility, high bending strength, rigidity, stability, accuracy and tolerance to humidity parameters of performance value are critical.

Sveza Birchply™ Birch Plywood is an answer to both interior and exterior applications where combination of physical properties with high class surfaces is necessary without any compromise.

Veneers

  • 100% natural whole piece or spliced Birch Veneers of 1.4mm thickness throughout the plywood without any gaps or open splits or joints.

Bonding

  • Phenolic resin cross-bonded weather resistant gluing according to EN 314-2 class 3 exterior.

Effect of humidity and moisture

  • Wood veneer is a living material and is subject to moisture movement according to surrounding conditions, which affects the flatness of panels. It is important to condition the panels to reach a moisture content near to the equilibrium of their permanent environment.

  • Like other wood-based panel products, Birch Plywood is also hygroscopic and its dimensions change in response to a change in humidity. A change of 1% in moisture content typically increases or decreases the length, width and thickness by 1% in dimensions and thickness. It is therefore desired that the edges are sealed with a suitable acrylic paint to prevent and/or control ingress of moisture and humidity and consequent swell in thickness and expansion in dimensions.

  • The recommended stocking conditions are 20°C and a RH of air of about 60%.

Appearance Grading Rules

Grade "B": Natural Whole piece surface has light and uniform colour. A few small pin knots and some brown streaks are allowed. Veneer of this grade is intended for natural finishes. Plugging is not allowed.

Gallery Item 1  Gallery Item 2 Gallery Item 3 Gallery Item 4

Grade "BB": Natural Whole piece surface has light and uniform colour. A few sound tight knots are permitted. Open knots and defects are eliminated and plugged with small oval or round colour matched veneer patches before gluing.

Gallery Item 1  Gallery Item 2 Gallery Item 3

Grade "CP": Natural Whole piece surface is very close to Grade BB. However, thin splits and tight knots are allowed. The oval or round plugging by veneer is allowed in unlimited numbers which may not be colour matched

Gallery Item 1  Gallery Item 2 Gallery Item 3

Grade "C": Natural Whole piece surface Open defects such as open knots and veneer splits are allowed. The surface remains unsanded. It is a cost effective solution in packaging and for crating where strength is more important than the appearance.
