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.

Class 2 (formerly called AW100 or MR) can also be produced upon request.
Formaldehyde emissions are below those established for Class E1 in conformity with the EN 636 standard. The low-emission class E1 panels do not cause a concentration of equilibrium in the air of the test chamber (defined in the EN 717-1 standard) greater than 0.1 ppm, the limit established by the World Health Organization for living and residential environments.

Triple-core poplar blockboard: bending strength and lightness

triple core poplar + HDF

triple core poplar blockboardWhen producing large-size sliding doors, dividers and partitioning, tables and bench tops, the risk of warping or bowing is very high.
The so-far unequalled solid wood solution, is triple-core poplar blockboard.
Triple-core blockboard is a special construction with 3-ply of cross-banded blockboard cores, overlaid by poplar veneer or thin HDF.
In comparison to any other kind of wood-based panel, this blockboard, available in the thicknesses between 36 mm and 60 mm, has superior bending strength, the lightness of Italian poplar timber (between 400 and 450 Kg/m3) and high screw-hold ability.

Trade names
Triplecore blockboard, Ecocore, lumber triple core plywood, triple core poplar board, cross-core poplar panel, 5‑ply Poplar Blockboard Panel, Pappeltischlerplatte, Staptischlerplatte, Stabpappelsperrholz, Stabilomassief, panneaux latté peuplier, alistonado de chopo, listellare pioppo tripla anima.

Construction
The triple-core poplar blockboard composition is a 5-ply construction. For example in 50 mm:
– about 2 mm poplar veneer cross grain (B)
– about 16 mm blockboard poplar core long grain (A)
– about 14 mm blockboard poplar core short grain (A)
– about 16 mm blockboard poplar core long grain (A)
– about 2 mm poplar veneer cross grain (B)

triple core blockboard

The poplar face is ideal for veneering. When the board is intended to be painted or laminated, the outer veneer is replaced by a 3 mm thin panel of HDF (high density fiberboard). This panel is called triple-core poplar blockboard + HDF.

And for very special paintings applications, to reduce the consumption (and costs) of paint, the triple-core poplar blockboard + HDF is also available overlaid with a 240 gr/m2 lacquering paper.

Triple core blockboardUsing this product, veneered, laminated or lacquered, the leading Italian designer Mauro Lipparini and furniture manufacturer Misuraemme brought a real innovation in the concept of bookcases with the Crossing product line, a versatile modular system of panels to create wall shelving: the thickness (38 mm) and the bending strength and lightness of poplar blockboard, give the system a stability that allows you to hang the shelf directly on the wall with brackets, creating an unusual “visible lightness“.

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).
Class 2 (formerly called AW100 or MR) can also be produced upon request.
Formaldehyde emissions are below those established for Class E1 in conformity with the EN 636 standard. The low-emission class E1 panels do not cause a concentration of equilibrium in the air of the test chamber (defined in the EN 717-1 standard) greater than 0.1 ppm, the limit established by the World Health Organization for living and residential environments.

HDF with plywood or blockboard sandwich panels

HDF and plywood sandwich panel

mdf+blockboardProduction of high quality door profiles and door components can be obtained with a sandwich panel, combining 2 or 3 plies of high density fiberboard (HDF) and plywood or blockboard as the core material.

This kind of board can guarantee high stability and moisture resistance, high bending strength and light weight.

The most common sandwich panels are made with a 3-ply construction, for example:
– about 13 mm HDF
– about 14 mm blockboard core or poplar plywood
– about 13 mm HDF
The inner core is produced by calibrating the blockboard cores (spruce, pine and poplar are the most common timbers used), so that there’s no significant thickness tolerance in single staves, and the final board is free from gaps.
In other applications, the core is made with poplar plywood with standard cross-banded veneer composition, or also with all veneers in the same long-grain direction.

The size of sandwich panels varies according to the specific market, however, the most common sizes are:
– 2200×1220 mm
– 2200×1260 mm
– 3050×1220 mm
in 40 mm and 44 mm thickness.
It is also possible to order products that are cut to size.

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.

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.
