RedBuilt pushes I-joist tech as global market heads toward $4.7 billion

RedBuilt is highlighting its engineered I-joists as demand grows in a market projected to nearly double by 2033. The company is positioning the products as a lighter, stronger option for floor and roof framing in residential and commercial construction.

Why it matters: - The global I-joist market was valued at $2.6 billion in 2024 and is projected to reach $4.7 billion by 2033. - The forecast implies 6.6% compound annual growth from 2025 to 2033. - Builders are using engineered I-joists more often for floor and roof framing because the products can improve structural performance while reducing lumber use. - RedBuilt is targeting that growth with engineered wood products designed for modern building code and installation demands.

What happened: - RedBuilt said its engineered I-joists use laminated veneer lumber flanges and oriented strand board webs. - Hayley Dunning, marketing communications specialist at RedBuilt, said the design makes the joists lighter, stronger and more dimensionally stable than traditional lumber. - RedBuilt said it manufactures I-joists in lengths up to 80 feet and offers parallel and tapered profiles. - The company said it can customize products to match project specifications.

The details: - North America holds 35.4% of the fastest-growing regional segment in the global I-joist market. - The United States accounts for 19.8% market share. - The commercial sector leads the market, and new construction is the largest segment. - Floor applications account for the largest share, followed by roof applications and other structural uses. - RedBuilt said its I-joists are built with high-quality LVL flanges bonded to OSB webs with advanced adhesive systems. - The company said the design helps resist warping, twisting and shrinking as wood adjusts to moisture changes. - The joists include pre-punched knockout holes for HVAC routing and easier wiring runs without extra drilling. - RedBuilt said the LVL flanges accept nails easily, which can reduce installation time and labor costs. - The company said controlled lamination and wood veneer layers help create predictable strength and enable longer spans between supports. - The products can reduce the need for intermediate bearing walls, posts, beams and some foundation components. - RedBuilt said the joists are manufactured with controlled moisture content to limit dimensional change in service. - That stability is intended to reduce callbacks tied to floor squeaks and ceiling cracks.

Between the lines: - The market data suggests builders are paying more attention to total installed cost, not just upfront material price. - RedBuilt is framing I-joists as a way to cut labor, waste and secondary structural material while preserving performance. - The company is also linking product design to code compliance and firefighter safety, which can matter in project approvals and specification decisions. - RedBuilt said it uses software modeling to balance flange thickness, web configuration and joist depth. - The pitch points to a broader construction trend: engineered wood is taking share where speed, consistency and longer spans are priorities.

What's next: - RedBuilt said it will keep investing in manufacturing technology and quality control systems. - The company said it will continue supporting architects, engineers and contractors with design guidance for specific projects. - The broader I-joist market is expected to keep expanding as builders adopt more efficient framing systems.

The bottom line: - RedBuilt is betting that engineered I-joists will gain more traction as construction shifts toward lighter, faster and more code-compliant framing systems.
