Timber is a type of processed wood that is used in a wide range of building applications. It is also one of the oldest building materials and is still preferred by architects because of its versatility, sustainability and cost-effectiveness compared to other building products.



The timber materials are chosen based on many factors as they vary by the working properties, aesthetic appearance, their function, production process, and many more. So, it is important to understand the difference, so that you can choose the product for the intended purpose. The timber materials are manufactured from different woods, there are two main categories the wood is classified into, softwood and hardwood, depending on the type of tree the timber comes from. 

These are normally sold by lengths and they are identified as boards, planks, and mouldings. The type of timber that has proportional dimensions are known as planks and boards, and the type that has a decorative pattern is known as spindle moulding and is widely used in skirting boards. The timber that is produced from hardwood is considered to be denser and heavier than softwoods and normally used in the construction of walls, ceilings and floors. 

There is also a choice of rough and smooth sawn finish, where the rough cut finished timber is normally used in the production of garden fence posts and some other general building work. In contrast, the smooth cut finish or planed edge timber is available in two variations PSE – planed square edge and PAR planed all around. Here at MGN Builders Merchants, we have a wide range of PSE type of timber products such as redwood timber and different types of PSE pine mouldings.

To assist you in the selection process here are some key factors to consider when choosing timber for your project:

  • The way the timber is stained/treated or painted.
  • A type of profile that has been used.
  • The function and purpose
  • Anaesthetic appearance
  • Working properties 
  • Manufacturing process 
  • Cost 

We have timber for almost any construction project, whether you need to build the structural supporting frames, interior decoration, furniture, or for external use. Please read on to find out more about the timber products that we supply their use and application.

Timber Based Materials 


Wood-based materials are playing an important role in the construction process one of the popular ones are sheet materials. Sheet materials are versatile wood boards that are produced from recycled or solid timber particles in the form of fibres, staves, and veneers, they are then hot pressed and bonded together with the addition of adhesive. They are used in almost all forms of structural and non-structural projects and interior designs. They are predominantly used in:

  • Flooring applications
  • Furniture making
  • Wall sheathing 
  • Roofing

The wood-based boards are produced in different grades and properties and should be chosen based on the project specification purpose.

For instance, wood panels like plywood are made from layers of wood whereas (MDF) medium density fibreboards are man-made panels that are produced from recycled material. The wood-based sheet materials function will vary greatly, as some wood panels might not be suitable for certain environments. If you are in doubt on what type of sheet materials would suit your particular project, please read on to find out the available options, their use and application.
