Lightweight particle board, made of poplar timber

poplar particleboard

Lightweight particle boardLightweight particle board poplar panels are unique both in their appearance and in their physical and mechanical properties. They have a compact core of environmentally-friendly poplar timber, and a fine surface with micro-particles with very light color, typical of the wood they are 100% made of.

The careful selection of poplar timber particles, mostly coming from trees discarded by sawmills and plywood producers, ensures excellent stability and high workability even at the edges, as well as ease of cutting, machining, milling, and molding processes. The inner layer is very compact and homogeneous and, thanks to peculiar poplar features, it allows long life to processing tools, as well as excellent screw-holding ability.

Lightness comes from raw material selection and a special production process: it simplifies handling and following manufacturing processes, and helps save shipping costs of finished products. Lightweight particle board poplar panels density goes down to 450/490 kg/m3 (compared to 550/650 kg/m3 of other kind of particle boards)!

Panels are suitable for finishing with melamine-impregnated papers, or coating with plastic laminates, finish foils, floors overlay, PVC, PP and veneers.

The standard dimensions most commonly produced are:
4220 x 1860 mm
4220 x 2070 mm
3760 x 1860 mm
3760 x 2070 mm
2800 x 2070 mm
Thickness ranges from 8 to 58 mm

Special sizes or thicknesses can be produced upon quotation and minimum quantity requirements.

Panels are available raw, melamine faced and veneered. Standard range or custom possibilities, upon request.

Bonding is made with certified urea-formaldehyde resin, suitable for panel use in dry conditions. The panel is compliant with Class 1, according to the requirements of EN 717-1 (single-value <= 8mgHCHO/100g – medium value <= 6.5 mgHCHO/100g) methodological standards EN 120, commercially known as E1.
Upon request, they also meets the requirements of the CARB 2 California Code of Regulation (FRO ATCM §93210.2 (a) Table 1, Phase 2) and TSCA Title VI – 40 CFR Part 770.

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.

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:

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.

triple core poplar + 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.

Okoume marine plywood

Okoume Marine Plywood

Okoumé plywood panels are produced with high-quality rotary-cut veneers of Aucoumea klaineana, specially manufactured to provide durability and longevity. They are very stable and can withstand exposure to severe weather conditions for prolonged periods of time.
“Marine” plywood panels are veneered-based panels of good durability with respect to fungal decay and bonding quality, which makes them suitable for the manufacturing and interior fittings of marine craft and for several applications in building construction. The durability derives from the resistance to biodegradation of the wood species used, combined with the weathering performance of the bonding quality and the high number of layers.

Marine plywood is one of the veneered-based products with the greatest value, nicest appearance and highest durability. Its performance makes this plywood particularly adequate for applications where both the decorative function and the mechanical properties are priorities, especially in the naval sector.
Its mechanical properties are similar to those of solid wood, but it allows for greater regularity and stability.

The standard dimensions most commonly produced are:
2500 x 1220 mm
3100 x 1530 mm
2500 x 1530 mm
Thickness ranges from 4 to 50 mm

Special sizes or thicknesses can be produced upon quotation and minimum quantity requirements.

The adhesive used for bonding marine plywood is a modified MUF system that satisfies the requirements of Class 3 for marine applications, while the bonding quality is checked according to EN 314 after a pre-treatment that simulates a long-time exposure to weathering agents that the plywood must withstand when in service. The best behavior of the panels is reached when their edges are adequately protected during use.
Panels are compliant with Lloyd’s Register – Norm BS 1088:2003 and, upon request, they are also available with FSC certification.

Usage and storage instructions
– Store the panels lying flat in a clean, shaded, dry place.
– Panels should be transported on a hard flat surface. Single panels can be rolled, but should not remain in this position for long periods.
– Do not expose the panel to sudden changes in humidity, temperature, and also protect it from sunlight.
– Glue the panels while they are brought into the desired shape. When the glue is dry, panel will retain its shape.
– High Pressure Laminate or paper-backed veneer can be applied during the initial curving process, or in a second step.
– Any wood glue can be used.

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.
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).
