High-Performance I-Joists for Durable and Efficient Construction

At Paradigm Lumber, we provide high-performance I-Joists designed to deliver exceptional strength, stability, and reliability for a wide range of construction applications. Engineered with precision and manufactured using advanced technology, our I-Joists offer an innovative alternative to traditional solid lumber, giving builders and contractors superior performance while optimizing material efficiency.


What Are I-Joists?

I-Joists are engineered wood products shaped like the letter “I,” consisting of top and bottom flanges made from laminated veneer lumber (LVL) or solid sawn lumber, connected by a sturdy web of oriented strand board (OSB). This design results in a lightweight yet incredibly strong structural component that can span longer distances and resist common problems found in conventional framing.


Benefits of I-Joists


  • Superior Strength and Stability – Designed to carry heavy loads across wide spans without warping, shrinking, or twisting.
  • Lightweight Construction – Easier to handle and install compared to traditional framing lumber.
  • Consistency and Reliability – Manufactured to exact specifications for uniform size and performance.
  • Material Efficiency – Reduces waste by maximizing the use of engineered wood and sustainable resources.
  • Design Flexibility – Allows for creative layouts with open floor plans and longer spans without the need for additional supports.


Applications of I-Joists

I-Joists from Paradigm Lumber are a trusted solution in residential, commercial, and industrial construction projects. They are widely used in:


  • Floor and ceiling framing
  • Roof structures
