The difference between LVL laminate and Plywood CE certification

The final uses of LVL laminate and Plywood plywood are different, which determines that the coordination standards and requirements of EU CE certification in the field of building structural parts are different. LVL veneer laminate and Plywood plywood are both made of wood veneers through hot pressing and gluing. What are the specific differences between them?

1. Name:

LVL: Laminated Veneer Lumber, Chinese: veneer laminate;

Plywood, Chinese: plywood.

2. Use

LVL veneer laminate is mainly used in construction and wood structures; LVL with average strength can also be used in furniture, decoration and packaging;

Plywood plywood is mainly used for decoration, furniture and packaging.

3. Structure

All LVL veneers are in the same direction, arranged along the grain, and the wood fiber direction of the adjacent layers is parallel;

Plywood is arranged vertically and horizontally, and the wood fiber direction of the adjacent layers is vertical.

4. Materials

LVL veneer laminated lumber is mainly poplar/pine + PF phenolic glue (waterproof, formaldehyde emission E0); Plywood is generally poplar/eucalyptus + MR urea-formaldehyde glue (general moisture-proof, formaldehyde emission E2, E1, E0 less).

5. Emphasis

LVL is mainly a product aimed at replacing sawn timber, emphasizing the enhancement of the longitudinal mechanical properties of the product and highlighting the anisotropy of wood;

Plywood is a transformation of the anisotropy of natural wood, emphasizing isotropy.

6. Features

LVL board has uniform structure, high strength and good dimensional stability, which can meet the use requirements of wooden structure buildings, bridges, furniture and transportation.

Plywood has better decorative properties.

EN 13986:2004+A1:2015 Wood-based panels for use in construction-Characteristics, evaluation of conformity and marking.

Certification system: System 1 or System 2+

Scope of application

This document defines wood-based panels for use in construction and specifies the relevant characteristics and the appropriate test method to determine these characteristics for wood-based panels, unfaced, overlaid, veneered or coated:· for internal use as structural components in dry conditions;· for internal (or protected external) use as structural components in humid conditions;· for external use as structural components;· for internal use as non-structural components in dry conditions;· for external use as non-structural components;· for use as structural floor decking on joists in dry or humid or external conditions;· for use as structural roof decking on joists in dry or humid or external conditions;· for use as structural wall sheathing on studs in dry or humid or external conditions.

It provides for the evaluation of conformity and the requirements for marking these products.

This document is not intended to be applicable to wood-based panels for use in non-constructional applications.
