We are distributors of a wide range of wood-based panel products including hardwood, softwood and birch plywood’s, moisture resistant MDF boards, Oriented Strand Board (OSB) and flooring grade chipboards. We can also offer real wood veneered boards with MDF core.

Oriented Strand Board - OSB

OSB is an engineered wood particle board formed by adding adhesives and then compressing layers of wood strands in specific orientations, resulting in a versatile, environmentally sustainable panel. This results in a structural engineered wood panel that shares many of the strength and performance characteristics of plywood which has become extremely popular in the construction industry. OSB has superb load-bearing properties, excellent cross dimensional stability and an attractive wood patterned finish.

The most common uses are as sheathing in walls, flooring, and roof decking.

Four grades of OSB are defined in EN 300 in terms of their mechanical performance and relative resistance to moisture.

  • OSB/1 – General purpose boards and boards for interior fitments (including furniture) for use in dry conditions.
  • OSB/2 – Load-bearing boards for use in dry conditions.
  • OSB/3 – Load-bearing boards for use in humid conditions.
  • OSB/4 – Heavy-duty load-bearing boards for use in humid conditions.

Structural Softwood Plywood

Including Formwork

Wooden formwork is often used to create moulds to hold concrete as it’s poured. These boards are either permanent fixtures or temporary ones – to be pulled away once the concrete sets. In most cases, the wooden formwork is temporary, and it is held in place using braces known as falsework. Plywood is one of the most commonly used types of wood for formwork because it is generally inexpensive and some types of plywood are resistant to water damage.

Hardwood Plywood

Hardwood plywood ranges are manufactured by carefully selected mills in China, Malaysia and Indonesia, capable of meeting all of today’s requirements, from EUTR legality audits to compliance with the European Construction Products Regulation.

There are several cores which can be within Hardwood Plywood.

Multi-Layered Core

Plywood with this core is often used for decorative applications where the edge is not hidden. Applications include drawer sides, children’s furniture, fixture components, and other applications where the core will be exposed.

Particleboard (PBC)

Raw PBC is composed of wood particles which vary in size bonded together. This is the least expensive core option for hardwood plywood, offering a smooth, void-free surface for veneer faces. PBC is very uniform in thickness and density.

Medium Density Fiberboard (MDF)

MDF is made in a production process similar to PBC except that all of wood particles are small and uniform like sawdust. MDF offers great stability and is the least likely to react when subjected to a measurable change in temperature or humidity. It offers a very smooth, void-free surface for veneer faces. MDF has greater strength and screw holding properties than particleboard and tends to be used in cabinets, furniture, fixtures and molding

Combi-Core Panels

These are constructed of veneer core inner plies with particleboard or MDF crossbands. They offer similar strength and stability to veneer core but has the void-free surface quality of PBC or MDF.Download Specifications – link timber-allied-hardwood-plywood pdf

Chipboard

Our chipboard is sourced from various producers including EGGER, Kronospan and Spano.

Made by gluing layers and fragments of recycled paper together to form a larger piece of material, chipboard has the advantage of being relatively cheap to produce. Heat and pressure are applied to the adhesive so the material becomes rigid and feels smooth. We supply chipboard in a range of thicknesses, from very thin to very thick.

Chipboard has a variety of uses. When laminated it’s often used to make kitchen furniture, bedroom furniture and general furniture. It can also be used for floor boarding (as long as it’s away from water /damp conditions).

Moisture Resistant MDF

Moisture resistant MDF is a versatile panel, with a high internal bond strength, used extensively for areas that may be subject to occasional wetting or humidity. Its smooth surface makes it suitable for painting, grain printing or the application of paper foils and veneers. The panel can be worked easily with all conventional woodworking machines. It saws cleanly and drills easily. It also shapes and routs well, without splintering or chipping.

NHBC approved for use as architectural mouldings, staircases and window boards – identified by its green colour.
