The Roofing Joists category at Build4Less encompasses a wide range of timber carcassing options, each tailored to meet various construction needs. These joists are available in both treated and untreated forms and come in varying sizes and strength grades, namely C16 and C24.

Treated vs Untreated Timber

Treated Timber: Ideal for external or moisture-prone environments, our treated timbers are imbued with preservatives, enhancing their resistance to rot and insect damage. They're perfect for outdoor roofing projects where durability is paramount.

Untreated Timber: Best suited for indoor or dry conditions, untreated timber offers a natural option. It's often chosen for its aesthetic appeal and is best used in environments not exposed to harsh elements.

Size Variations

Our joists come in a multitude of sizes, catering to different structural requirements. From slender 25mm x 38mm timbers perfect for lighter applications, to robust 47mm x 250mm joists designed for more demanding tasks, we provide a comprehensive range to suit your specific needs.

Strength Grades: C16 and C24

  • C16 Grade: This is a standard grade for general construction purposes. Suitable for most roofing projects, C16 timber offers a reliable balance between strength and cost-effectiveness.

  • C24 Grade: This higher-grade timber provides greater strength and load-bearing capacity. It’s the go-to choice for areas requiring robust support, such as heavy roofs or high-traffic floors.

     

Selecting the Right Joist

The choice of joist depends on the project's specific demands:

  • For Residential Roofing: A standard C16 grade often suffices, balancing cost and performance.
  • For Commercial or Heavy-Duty Applications: Opt for C24 grade joists to ensure enhanced durability and load capacity.

  • Environmental Considerations: If your project is in a moisture-prone area, treated timber is a must. In drier, indoor settings, untreated timber is a suitable choice.

     

Remember, the appropriate joist not only ensures the safety and longevity of your construction but also aligns with the budgetary and aesthetic aspects of your project.

Product Groupings

  • Small Dimension Joists (25mm thickness): Ideal for lightweight applications and non-load-bearing structures.
  • Medium Dimension Joists (47mm thickness): The most versatile option, suitable for a wide range of residential and commercial roofing projects.

  • Large Dimension Joists (75mm and above): Reserved for the most demanding applications, where maximum strength and support are non-negotiable.
