With such a variety of timber types and timber uses, it can sometimes be tricky figuring out what you need. Our buyer's guide to timber will help you work out the best timber for your project.
Planed & Machined Timber
Planed timber is timber that has been planed down to give the edges a smooth finish. Machined timber is passed through a moulder to get the same smooth edges. The pre-finished edges make planed or machined timber a great choice for interior joinery.
Cladding is applied onto walls vertically or horizontally to create an aesthetically pleasing finish. Typically, cladding can be used to create a coastal, nautical or rural look and feel but can be used in a number of ways on a variety of different
buildings, inside or out.
Planed timber is planed or machined on the edges to create a smooth surface. This makes it perfect in applications where it will be visible, and is incredibly popular for interior joinery, framing, shelf supports and door linings. PSE can be used when describing planed timber and stands for ‘planed square edge’ or PAR which is ‘planed all round’.
Sawn timber describes any timber that has been cut from a larger log or bit of wood into what will generally be a rectangular shape. Suitable for use in an interior setting, timber that is to be used outside will need to be treated. Great for structural work, sawn timber has endless uses and is a great material to use for a variety of projects. There are a few terms you should know if you’re looking to purchase sawn timber;
- Finished Size or Minimum Finished Size
The finished size for timber refers to the minimum size it will be when the edges have been planed. This will usually only be a few millimetres different to the nominal size of the wood, but if you’re working with precise measurements this could be important!
This refers to the method for application of protective treatment. Timber is put into a vacuum where pressure is applied to force chemical preservatives into the wood. This will generally protect it against insects and fungal decay, making it suitable for use outside.
These grades refer to the structural quality of the timber. C16 is generally used for floor and roof joists with C24 being a higher grade, making it suitable for structural applications.
The word ‘Batten’ is typically used to describe a length of timber applied to a roof in order to fix tiles or slates in place. For roofing applications, battens must be graded to specify they are suitable for use in this manner and must comply with BS 5534. Ungraded battens can be used in a number of projects for holding materials in place or fixing to vertical surfaces.
CLS stands for Canadian Lumbar Standard which is used to describe wood that is suitable for building the timber framework for houses in Canada. Its high strength and relatively low fire risk has made it popular throughout Europe and is ideal for use in creating partition walls or for boxing in.
Kiln Dried Timber
Kiln dried timber has been dried out slowly to remove moisture and ensure stability in the wood. Our untreated timber will have rough sawn ends and is great for internal structural work as it will not be resistant to exposure outdoors.
Treated timber is timber that has had a treatment applied in order to make it more resistant to weather and moisture. Suitable for use inside and out, treated timber has endless applications.
Typically used as platforms in scaffolding to allow construction, maintenance or repairs to be carried out safely at height that is not reachable from ground level. Scaffold or scaffolding boards have metal reinforcements at each end to strengthen further to ensure they last.
