Types of Timber for Every Project

At Howarth Timber & Building Supplies, we offer an extensive range of timber types to suit all construction, landscaping, and DIY applications. Whether you're working on structural builds or decorative finishes, we have the right timber products to get the job done. As a renewable and recyclable material, timber is not only versatile but also an environmentally responsible choice.

Sheet Materials

Our selection of sheet materials includes plywood, chipboard, OSB, and MDF – all engineered timber solutions that are ideal for flooring, panelling, cabinetry, and packaging applications. These versatile sheets are strong, easy to work with, and essential for a wide range of building tasks.

Structural Timber & Carcassing

We stock structural softwood carcassing timber, which is slow-grown and strength-graded, making it perfect for heavy-duty applications like floor joists, roof rafters, wall studs, and timber framing. This type of wood carcassing meets UK building regulations and provides reliable performance on-site.

Roofing Battens

Roof Battens are treated, sawn timber sections used to support roof tiles or slates. They’re essential for maintaining structural integrity and proper alignment in roofing systems.

Timber Mouldings

Our wide range of timber mouldings includes skirting board, dado rails, floorboards, architrave, door linings and lasings – perfect for both functional and decorative finishes. For framing and internal panels, Scant and CLS timber are excellent choices due to their smooth finish and dimensional accuracy.

Fencing Timber

We offer Timber Fence Panels in a variety of styles, providing both privacy and aesthetic appeal for gardens and outdoor spaces. Choose from traditional to contemporary fencing designs to complement any landscape.

Timber Decking

Create stylish and functional outdoor spaces with our range of timber decking. Ideal for patios, garden paths, or entertaining areas, decking is a durable and attractive alternative to paving.

Timber Sleepers

Timber Sleepers are perfect for building raised beds, garden borders, retaining walls, or rustic outdoor steps. Available in treated softwood or reclaimed styles for added character.

PSE Timber

Planed Square Edge (PSE) timber is a smooth, finished timber ideal for joinery, furniture making, and interior framing where a clean, professional appearance is needed.

Hardwood Timber & Cladding

Our premium hardwood timber is naturally strong, weather-resistant, and long-lasting, making it suitable for external applications like cladding and structural mouldings. Use hardwood cladding to protect external walls from the elements or add a modern finish to interior areas such as bathrooms and poolside rooms where moisture resistance is key.
