MDF & MDF Mouldings

MDF is an engineered wood product consisting of softwood fibres bonded together under high heat and pressure.  MDF is a very smooth, high quality board with an equal density across all of the panel.  It is easily machinable and has no ‘natural defects’ such as knots as seen in other panel products.

We stock a full range of MDF types, sizes and thicknesses including Standard Moisture Resistant MDF, Exterior MDF and Flame Retardant MDF.

OSB (Oriented Strand Board) is an engineered panel product alternative to plywood.

It is manufactured by pressing together three separate layers – each consisting of wood strands orientated in a differing direction for extra strength- under high temperature and pressure.  The resulting product is a highly durable, rigid and reliable board that is suitable for a wide variety of applications similar to plywood products.

OSB has properties very similar to plywood but has a number of clear benefits. Firstly, OSB suffers from no natural defects such as weak areas, knots and core voids as it is made from wood strands.  Secondly, it can be manufactured from environmentally friendly and fast growing wood species and can be recycled at the end of its useful life.

It can also be drilled, sanded, sawn, stained, planed, painted and routed. We have a complete range of OSB available for immediate delivery.
