Sheet Materials

Pentagon works closely with some of the UK's largest manufacturers and importers so that we have constant access to, and can supply, the highest quality sheet materials at the most competitive prices


Plywood is a wood manufactured out of many sheets of veneer, or plies, pressed together and glued, with their grains going in opposite directions. Plywood tends to be extremely strong and is treated in many different ways depending upon its intended application. Plywood is also referred to as an engineered wood, although it is made from a composite of wooden materials.


Medium density fiberboard, or MDF, is a composite wood product. It is made out of wood waste fibers glued together with resin, heat, and pressure. MDF is appropriate for many applications, from cabinetry to moulding, because it is smooth, uniform, and won't warp.


OSB is the smart alternative to plywood. OSB is made with layers of precisely engineered wood strands. It is coated with exterior resins interwoven in a lattice pattern and then compressed under intense heat and pressure. This manufacturing process adds to the extra strength, rigidity and moisture resistance.


Blockboard is a wood based panel, made up of a core of softwood strips glued together. The strips may be up to about 28mm wide and are placed edge to edge and sandwiched between veneers of softwood, hardwood or thin MDF or particleboard, glued under high pressure. The internal strips are generally made of light weight poplar wood or spruce. Blockboard is used to make doors, tables, shelves, paneling and partition walls. It is normally used inside due to the type of glues used during manufacture.


Laminboard consists of a central layer of edge glued battens of between 24 and 30 mm width, covered on both sides with a facing veneer. Laminboard is a higher grade variant of blockboard in which the central core consists of thinner 5-8mm battens or veneer arranged 'on edge'. Blockboard plywood used to be made by joiners themselves, and is sometimes still known as joinery board.


Chipboard is an engineered wood product which contains melamine, a chemical compound which has a number of uses. Melamine can be found inside almost all chipboard products, and it is also used as a facing material to make veneers and laminates. Chipboard can be used as a base or sub-flooring for all types of floor coverings including carpet, stone, wood and ceramic tile. Chipboard floors are not usually used for main floor coverings, the pressed sawdust and resin effect is not the most attractive look.


Decorative boards are manufactured from core products such as plywood. MDF and blockboard and are used mainly as decorative panelling. They are available in many finishes and designs and can be painted to suit.
