Laminated blockboard, a durable decorative lumber core

Laminated Blockboard

One of the latest industrial applications on blockboard, consists in overlaying the panel with a durable decorative surface material, called continuous high pressure laminate (cHPL or CPL). This panel has special performance properties including chemical, fire, and wear resistance, which add to the well-known great features of blockboard.
Some of the most common enforcements are structures for upper and lower kitchen cabinets, workbenches, child room and office furniture, and all kinds of articles that require excellent resistance to scratch and hard use.

Trade names
Laminated blockboard, melamine-faced blockboard, formica laminate blockboard, laminated lumber core, melamine-impregnated film-coated block board.

Construction
cHPL with a thickness of 0,5 mm is laminated on blockboard with PVAc (D3) glue and is available with two kinds of raw panels as core material: the 3-ply or 5-ply construction (without any HDF), or with the 3-ply or 5-ply construction with a thin HDF under the laminate as per following pictures.
The thin HDF panel under the cHPL overlay totally eliminates any kind of telegraphing defects that might sometime appear on the veneer core, so it’s highly recommended.

Blockboard + HDF (3-ply) + cHPL laminate
Blockboard + HDF (3-ply) + cHPL laminate
Blockboard + poplar veneer + HDF (5-ply) + cHPL laminate
Blockboard + poplar veneer + HDF (5-ply) + cHPL laminate

cHPL laminates are available in a selected range of colors and wood grains and finishings, well integrated with the current trends and needs of the market.
Custom laminates are available upon request.

Engineered parquet and floorings

Wooden floors are nothing new, but parquet floors have seen a recent resurgence as more people are starting to introduce these elegant and sophisticated styles in newly built homes or whilst renovating old properties. The patterns are timeless and classic, and always look chic.

The word parquet comes from the French ‘parchet’ (short for ‘parc’, literally meaning “a small enclosed space”). In the XVII century, parquetry became very popular under the name ‘parquet de renaissance’, which replaced the marble floors in the bedroom of Louis XIV himself. From that point onward, parquetry became a symbol of taste and luxury which only the rich could afford until the XX century when machines finally made the process cheap and accessible to everyone.

Structurally, parquets can be divided into three major groups:
– solid: made from solid wood blocks of parquet flooring
– engineered: usually created from multiple layers of hardwood and plywood
– parquet overlay: manufactured from much thinner wood pieces and commonly installed on top of already existing floors.

As far as engineered wood is concerned, there are mainly three range of products:

Block-board, the solid lumber core panel

3-ply spruce blockboard

3plyspruceblockboardBlock-board (also called lumber core) is a timber material consisting of a core of wooden strips placed between two layers of veneers (3-ply in all), with extraordinary characteristics of bending strength, lightness and screw-hold ability. As it’s a real solid-wood alternative to timber, suitable for the production of high-quality and long-lasting furniture, furnishings, partition walls and cabinet-making.

Composition
A. The center of the panel (block-board core) is a solid slab generally made with side-glued lumber strips in the width of 28-38 mm; the most common kiln-dried soft wood timber species used in the cores are poplar, spruce and pine.
B. The block board core (long-grain) is then glued under high pressure with one layer of crossband veneer sheet on each side. The veneer used is normally poplar or Ceiba pentandra (exotic veneer from timber plantation wood, also called fromager or fuma), with a minimum thickness of about 2 mm per side.

Blockboard for door jambs, door frames, and architraves

Double core blockboard

Blockboard Door JambBlockboard – unlike MDF – is a high-quality product with a long-lasting quality effect, guaranteeing long-term stability and non-deformability.

Door jambs, door frames, and architraves are some of the most common applications for double-core blockboard.

The normal double-core composition is a 5-ply construction:
– about 2 mm veneer cross grain (poplar or fromager) (B)
– about 16,5 mm blockboard core long grain (spruce, pine or poplar) (A)
– about 3 mm veneer cross grain (poplar or fromager) (B)
– about 16,5 mm blockboard core long grain (spruce, pine or poplar) (A)
– about 2 mm veneer cross grain (poplar or fromager) (B)

Double core blockboard draw

This kind of board is ideal for producing veneered door jambs.

When raw door jambs are covered with laminates like CHPL, sometimes the required double-core construction is as follows:
– about 3 mm MDF
– about 15,5 mm blockboard core long grain (spruce, pine or poplar)
– about 3 mm veneer cross or long grain (poplar or fromager)
– about 15,5 mm blockboard core long grain (spruce, pine or poplar)
– about 3 mm MDF

Recently a new 4-ply construction has appeared on the market:
– about 2 mm veneer cross grain (poplar or fromager)
– about 18 mm blockboard core long grain (spruce)
– about 18 mm blockboard core long grain (spruce)
– about 2 mm veneer cross grain (poplar or fromager)
It is produced by calibrating the blockboard cores, so that there’s no significant thickness tolerance in single staves, and the final board is without gaps: milling or lamination will end up on a massive timber surface, without other potential grain problems.

The length of door jambs varies according to each market tradition, while width is customized by each manufacturer, so blockboard is normally produced in custom sizes and then cut to size by the end user.
However, the most common sizes are:
– 2180×1880 mm (or cut at 2180×930 mm)
– 2200×1220 mm
– 2300×1220 mm
– 3050×1220 mm
in 39, 40, 44 mm thickness.

For other sizes and thicknesses, refer to this page.

Bonding of the faces is made with urea-formaldehyde glue (UF) (formerly called IF20), while the lumber core is bonded with PVAc (D3), in compliance with the provisions of the EN 314 standard.
After suitable treatment in view of resistance to humidity, the board complies to Class 1 requirements for the use of boards in dry environments (EN 636-1).
