FAQ
All of our C16 and C24 graded timber is regularised
Regularised timber is timber that has been processed to have a uniform shape and size. This means that the wood has been sawn and planed to remove any irregularities and ensure that each piece of wood has consistent dimensions. Regularised timber is often used in construction, particularly in the framing of buildings, as it is easier to work with and can be more efficiently installed than irregularly shaped timber.
We have one of the largest ranges of timber lengths, dimensions and grades available to buy online.
The variation you require will determine the exact lead time and delivery method.
Most orders arrive within 3-4 days, the maximum is 7 days. Please get in touch before you order if you need a specifc delivery date.
Delivery charges vary by postcode. To find out the delivery charge, add the item(s) you require to your basket and select CALCULATE SHIPPING at the bottom of the page.
Some orders are delivered on our own vehicles based in Leicestershire and Cheshire. We also use carriers including Yodel and Tuffnells. For some sizes and locations we use regional distributors.
If you'd prefer crane offloading rather than tail lift vehicle offloading for your brick order then this service is available for the majority of bricks that we sell. Charges are shown at checkout.

Built for Fire Safety Compliance
Wisa fire rated plywood is treated to meet Class B flame spread requirements, making it suitable for fire-rated wall linings, roof decks, and floors in commercial settings.
The treatment penetrates through the full thickness of the board, giving it consistent fire resistance throughout—not just a surface-level layer.
Strength for Load-Bearing Performance
Built from cross-laminated spruce veneers, this plywood delivers structural strength while maintaining flexibility and low weight. Use it in walls, roofs, or temporary hoarding.
Easy to Work With
Cut, screw, or nail this board using standard tools. It performs well in both dry and moderately humid conditions, reducing installation time and complexity on site.
Ideal for Large-Scale Projects
Used across schools, healthcare facilities, and housing developments, Wisa fire-rated plywood offers a reliable material choice that supports acoustic and fire regulations alike.
Multiple Thicknesses for Custom Fit
Choose from 6mm, 10mm, 12mm, and 16mm board options depending on your structural or lining requirements. Each board covers a full 2440x1220mm (2.98m²) area.
