Timber 38mm
Timber is where real building starts. The feel of solid wood. It is the backbone. Frames, floors, structures and supports all begin here. UK timber is chosen because it behaves predictably on site. It cuts clean. It fixes easily. It carries a load without fuss. From a small domestic job to a full build, timber is the material builders trust when the structure matters more than the surface. Whether sourced from a local timber yard or a reliable supplier timber range, good timber feels solid in the hand and stable in use.
What is timber?
Timber is a building material made from wood supplied in standard sizes and strength grades. It is sold ready to use, straight, dry and easy to work with. This is the material used when something needs to be built properly, not just covered or finished.
UK timber is commonly softwood prepared for structural work. It comes from timber merchants and timber yards in lengths that are easy to handle on site. You cut it, fix it and move on. No surprises. That is why timber remains the first choice for everyday construction.
What are timber lengths used for?
Inside a building, timber forms the structure you do not see. It is used for stud walls, internal frames and partitions. Straight sections, clean lines and easy to work with. Timber is also used as floor joists. These support timber floorboards and full flooring systems. In roof construction, larger sections are used for rafters, ceiling joists and main supports. This is the standard material for carcassing and everyday structural framing. Treated timber is used where moisture is part of the job. At ground level. On external walls. In areas that are exposed to damp or changing weather. Outdoors, it forms the base of many garden builds, including decking frames, raised platforms, pergolas, gazebos and other timber garden structures. In landscaped spaces, timber is used for garden steps, raised beds, sleepers, play areas and built-in outdoor seating, where strength and durability matter. Timber also forms the structural frame for garden sheds, log stores, bin stores and timber outbuildings. It is used beneath patios, along walkways, and anywhere level changes need proper support. Reliable and structural, it is designed to do its job quietly, whether inside the house or out in the garden.
What types of timber are there in UK?
The timber range includes several main types used in everyday construction.
Treated timber is wood that has been pressure-treated for protection. It is supplied in standard construction sizes and used for framing and structural work, including areas where the wood may be exposed to moisture.
CLS timber is kiln-dried and planed with softened edges. It is easy to handle and commonly used for stud walls, internal framing and general carcassing.
Hardwood timber may also be used on certain projects where a different finish is required, alongside the softwood timber used for most structural and everyday construction.
Timber is also supplied by strength grade. C16 timber is used for standard structural work. C24 timber is used where higher strength is needed. The range is available in a wide selection of sizes to suit different building tasks.

What timber is used for stud wall?
Stud walls are usually built using softwood structural timber, most commonly CLS timber or C16 graded timber. These sections are straight, easy to work with, and designed for internal framing.
What timber to use for decking frame?
For decking frames, always go with pressure-treated timber. It handles moisture much better and won’t rot as quickly outside. Size depends on how big the deck is and how much weight it needs to carry, but treated timber is the right starting point every time.
Why timber is used in construction?
Because it works. Timber is strong, light enough to handle on site, and easy to cut and fix. Builders know how it behaves, so there are no surprises. That’s why it’s used for everything from frames to roofs.
Which timber for outdoor use?
Use treated timber only. Untreated wood won’t last outdoors. Pressure-treated timber is made to cope with damp, rain and changing weather, so it’s the safe choice for external jobs.
