47mm x 100mm Sawn Treated Timber C16/C24 (4" x 2") 3m

What Is 4x2 Timber 3m?

Sawn Treated Timber (4x2) 3m is a premium treated timber available in both C16/C24 grades. Treated timber is often used to build partition stud work, in conjunction with plasterboard and insulation - such as Rockwool RWA45 100mm - to provide acoustic performance.

The pressure treatment applied to timber helps to prevent both fungal and insect attack. This process ultimately prolongs the life of the timber and protects it from both rotting and splitting.

We supply high quality 50x100 timber in various lengths: 2.4m, 3m, 3.6m, 4.2m, 4.8m and 6m with a consistent thickness of 47mm. 

Please Note: The finished size of our carcassing timber may vary slightly from the nominal dimensions. You can expect to receive timber that is finished with a thickness 2mm less and a width 5mm less than the nominal measurements stated. Colour and finish are representative only and may vary slightly as this is a natural product.

4x2 Timber 3m C16/C24 Applications

Despite their difference in grade, both C16 and C24 timber will perform well in general construction projects; while C16 timber is of slightly poorer quality than C24, it is still robust and resilient, making it suitable for strength and load-bearing.

However, for larger-scale projects (or in applications where strength is vital, such as balconies, terraces and bridges) we recommend using the stronger, more reliable C24 timber grade.

Thanks to the protective treatment of the timber, 47x100 treated timber can be used in many different indoor and outdoor applications such as: 

• Flooring
• Roofing - rafters/joists in a loft floor
• Walling
• Decking joists 
• Carcassing timber in floor joists
• Garden furniture and other outdoor projects 

What Does C16/C24 Carcassing Timber Mean?

C24 grade is superior to C16, offering greater strength with more knots and fewer defects. This suits it to tasks which require durability and sturdiness, namely structural applications, such as floor joists or roof battens.

C24 timber is a premium choice that can support higher loads and wider spans. Only good quality timber imported from areas where the weather conditions demand a slower growth rate (and hence a tighter grain) achieves a C24 grade.

Provided it is pressure-treated, C16 timber can be used externally in an outer structure of a building, as well as in decking. C16 graded timber is sturdy enough for most tasks and will satisfy performance requirements at a lower cost than C24 timber.

Pressure Treated Timber Benefits

There is a wide range of timber types on the market from treated wood, untreated wood and sawn carcassing timber. It is essential to use good quality treated timber for your construction projects as timber is usually located in places that are not easy to get to. This means we usually have no way of knowing if parts of the structure are under attack from insects or dampness, thereby weakening it.

Let's get into the details of treated timber's many other benefits: 

• It is treated to resist rot, decay and insect attacks
• The most durable timber option, making it ideal for outdoor use
• Thanks to its treated nature, treated timber is also low-maintenance
• You won't have to spend time and money regularly maintaining it
