LAMELLAR WOOD IN FIR AND OAK TIMBER
The name “Lamellar” describes the method of compressing and gluing pieces of wood together to create a stronger, more durable, and more stable product.
Checked and certified

Greater strength

Using glued strips of timber, with the grain of the wood in a parallel direction, the strength and mechanical properties of the wood increase dramatically. Laminated wood is much more resistant to deformation, especially in hot and humid conditions. It is much stronger than a solid wood of the same size. Glued laminated timber can usually be seen on the roofs of large swimming pools, and other structures that are subject to extreme environmental conditions.

Technical specifications

  1. Species: Fir or Oak
  2. All lamellar profiles can be worked in two different versions: KKK: all finger joint layers, with joint length on the outer layers not less than 210 millimeters, usually 6,000 millimeters in length and other possible lengths. DKD / DKK : Two layers of continuous surface (DKD) or with one continuous surface layer, and 2 layers of finger joints (DKK).
  3. Size range: 12-40mm thick, up to 1,220mm wide, and up to 6000mm long. Dimensions: 63 (21 21 21) x86x800-4.000 mm – 72 (24 +24 +24) x86x800-4.000 mm
  4. Continuous pieces up to 6,000 mm, with customized dimensions available.
  5. Profile: 3 layers; solid outer layers with intermediate layer FJ or 3 layers all FJ

Types of glue

COSCO Nobel Glue (DIN EN 204) This is the European standard which is well known as a worldwide standard of water resistance for glued wood. The EN204 test has 4 classifications.

Table of durability classifications with climatic conditions and fields of application:

  • D1 indoor use, where the temperature only occasionally exceeds 50 ° C for a short period of time and the humidity contained in the wood is 15% maximum.
  • D2 indoor use with occasional and short-term exposure of condensed water and / or occasional high humidity as long as the moisture content of the wood does not exceed 18%.
  • D3 Interior with frequent and short exposures to condensed water and / or exposure to high humidity. It can also be used for outdoor applications, without exposure to the elements.
  • D4 Interior with frequent and long exposures to condensed water.

Degree of quality

  • Grade A:absence of wood grain knots (knots allowed <1mm), small healthy knots <5mm, wood grain with sapwood.
  • Grade B: Wood grain knots <5mm, healthy knots <10mm, wood grain with sapwood.
  • Grade C: wood grain knots <10mm, healthy knots <30mm, wood grain accentuated with a lot of sapwood.
  • Grade D: all defects allowed, some defects can be repaired with putty.
