Sawn Timber

About Our Sawn Timber Range

In this dedicated “Sawn Timber” section you’ll find everything from construction-grade softwood boards to structural joists, battens, and sawn treated timber suitable for external use. According to the site, the category has sub-filters like Treated, Batten, Softwood, PAR (planed all round) and others.

Our range of sawn timber is selected for structural integrity, dimensional accuracy and durability. For external applications or high-moisture conditions, our treated sawn timber options ensure long-term performance and reduced maintenance. Meanwhile, our rough sawn timber provides the aesthetic and structural qualities needed for rustic builds, garden sheds or creative joinery.

Choosing the Right Sawn Timber Size and Treatment

Selecting the correct sawn timber sizes and treatment depends on the application. For general internal carpentry or framing, planed all-round (PAR) softwood in standard sizes (e.g., 38×89mm, 47×100mm) is often sufficient. For external structural works — such as bearers, decking joists or garden buildings — opting for treated sawn timber (e.g., pressure-treated with preservative) is wise.

If aesthetics are important — such as exposed timber beams or timber cladding — then rough sawn timber can deliver a textured character finish. When installing externally untreated timber, ensure correct ground clearance, drainage and apply a wood preservative to prolong life. Burnt Oak Timber’s stock includes both untreated and treated boards, giving you the flexibility to match budget, durability and usage requirements.

Installation Guidance & Practical Tips

• Always check that the sawn timber you select meets the required specification for the job: load-bearing vs non-load bearing, treated vs untreated, width/thickness & length.
• For external usage, choose treated sawn timber to resist rot, insect attack and weathering. Ensure correct ground clearance and ventilation around timber.
• If using rough sawn timber, allow for its rustic finish — it may require planing or sanding if a smooth surface is needed.
• Ensure correct storage of your timber: keep it dry, level and under cover where possible to prevent warping, twisting or cupping.
• Cut timber to size as required, allow for off-cuts and wastage. Check for straightness, knots or defects when purchasing.
• For paint or stain finishes, untreated boards should be primed/sealed, whereas treated sawn timber may already be pre-treated and ready to accept decoration.
