100% natural whole piece or spliced Birch Veneers of 1.4mm thickness throughout the plywood without any gaps or open splits or joints.
Face veneer: Qualities B and/or BB as may be required.
Cross-bonded interior gluing according to EN 314-2 (Plywood - Bonding) class 1 interior.
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%.

Reuses
Typical number of reuses is likely to be in the range of 15-20 times. However, this will vary according to many different factors including good site practice, the required concrete finish, the amount of care taken when compacting the concrete, handling and storage of panels, type and quality of release agent used on the panels before concreting.
The number of times the plywood can be reused is only intended as an approximate guide. It does not imply any form of warranty. The actual number of reuses will depend on several factors other than the plywood.
