MDF, OSB3 or plywood – which one does your job actually need?

They get lumped together as sheet materials, but they're built differently, priced differently and suited to different jobs.

Get the wrong one and at best you're paying over the odds; at worst, you're re-ordering once it's already been cut and fixed.

Our new guide breaks down:

✔️ What each material is and how it's made
✔️ Best uses (and limitations) for MDF, OSB3 and plywood
✔️ Which board suits your specific project type
✔️ How each one cuts, fixes and handles on site
✔️ A side-by-side comparison table to help you decide

Whatever you're building, we'll help you pick the right board first time.

Planning a loft conversion or a home extension this year?

Getting the timber spec right from the start keeps your build on programme – get it wrong, and you're looking at delays, re-orders and a site standing idle while you wait.

Our new buyer's guide covers:
✔️ What timber a loft conversion typically needs – floor joists, roof timber and sheet flooring
✔️ What timber a single-storey extension typically needs – framing, roofing and boarding
✔️ Choosing between C16 and C24 structural grades
✔️ Getting your quantities and delivery timed right, phase by phase
✔️ A quick-reference checklist for the whole project

Whether it's a full loft conversion or a rear extension, we'll help you specify the right grades, sizes and quantities from your drawings.

Formwork timber builds the structure. Formwork plywood shapes the finish. Get either wrong, and it shows in the concrete.

Our new buyer's guide breaks down:

✔️ Formwork timber vs formwork plywood — and why most systems need both
✔️ Film Faced, Pourform and Tulsaform panels compared
✔️ How reuse counts (up to 10–15 pours) affect your total cost per pour
✔️ Matching the right panel to your finish and pour cycle
✔️ Standard sizes we hold in stock, ready to go

Whether you're pricing a single domestic pour or running a repeat cycle across a major infrastructure programme, we'll help you specify it right first time.
