Sector Insights – Housing Demand Fuels Residential Segment Growth

In terms of sector, the residential segment is expected to contribute the highest share of 58.3% in the market in 2025 owing to continued urbanization and growing demand for housing around the world. As populations swell in major cities due to employment opportunities and better standards of living, the need for new residential construction rises accordingly. The residential segment benefits from government initiatives in many countries to promote home ownership and provide low-cost housing. Affordable mortgage rates and tax incentives further stimulate property purchases.

Rising incomes also enable more people to invest in homes compared to previous generations. This stimulates renovation and remodeling activities within existing housing stock. The widespread popularity of open plan living has increased the use of I-joists in flooring systems to allow for fewer but stronger load-bearing walls. Younger professionals and families prefer flexible floorplans that can accommodate various uses. I-joists provide architects and builders greater design freedom.

Additionally, the aging of population demographics means many older homeowners are refurbishing homes to accommodate mobility needs. Features like zero-step entries and wide doorways require reinforcing walls and floors with I-joists. Related industries like furniture and home appliances catering to retirees also support renovation spending.

Stable macroeconomic conditions and abundant employment keep housing demand resilient despite short-term fluctuations. Builders consistently rely on innovative yet cost-effective solutions like I-joists to deliver quality homes within budget. This segment is poised for continued growth riding on demographic and lifestyle shifts underway.

Construction Type Insights – New Construction Leads due to Housing Shortages

In terms of construction type, the new construction segment is expected to contribute the highest share of 68.2% in the market in 2025 and its prospects remain positive. After weakness during the economic slowdown, construction activity has picked up supported by low interest rates and rebounding developed markets. Many regions still face housing shortages that will sustain new builds over the foreseeable future.

Governments extensively use construction spending as an economic stimulus contributing up to 10% of GDP growth in some countries. Mega-projects involving transport infrastructure, utilities, commercial, and residential space have been initiated around the world. Many cities face population influxes necessitating the expansion of built environments which boosts all construction types.

New techniques assist high rises, bridges and complex buildings to be raised faster than before using pre-fabricated components like I-joists. Their light weight is an asset for cranes maneuvering modules high off the ground. Sustainable features required in modern designs are conveniently integrated with I-joists. Their engineered qualities comply with evolving building codes as well.

While recessionary pressures remain, the construction sector has proven resilient over economic cycles indicating steady prospects for new builds. Replacement activity also consistently expands the addressable market for I-joists with building stocks aging globally.

Application Insights - Floors Drive Robust I-joist Usage

Based on application, the floors segment is expected to contribute the highest share of 54.8% in the global i-joist market in 2025, owing to their widespread use. Flooring systems represent a significant portion of a building's load-bearing structure. I-joists play a critical role in modern construction by providing stiff, strong and cost-effective floor framing solutions.

Relative to solid lumber joists, I-joists allow much longer spans between load-bearing walls resulting in much more open floorplans. Coupled with their engineered strength and rigidity, I-joists better handle deflections from heavy appliances, furniture and live loads. This versatility appeals to contractors constructing multifamily units and large commercial spaces.

Advancements like rim boards and fusion welded webs have further enhanced I-joists' performance as floor joists. Their dimensional consistency and square edges simplify subfloor installation versus uneven solid lumber. Sheathed floor systems using I-joists integrate well into wall systems for buildings.

With sustainability increasingly prioritized, I-joists contain a higher recycled content than dimensional timber and contribute to maintaining forest stocks. Their light weight also lowers transportation costs. Overall, I-joists have become a mainstay in modern floor construction due to unmatched structural properties and efficiency over alternatives. Floors represent the largest application segment for this product type globally.

Global I-joist Market Driver - Rise in infrastructure projects

With rapid urbanization taking place across major cities in both developed and developing nations, the demand for new residential and commercial infrastructure has surged tremendously over the past decade. Governments around the world have undertaken massive road, rail and airport construction projects to accommodate the growing population and ease congestion issues in metropolitan areas. Infrastructure spending is playing a key role in boosting economic growth and creating local job opportunities.

Several emerging economies in Asia Pacific and Latin America have also witnessed rising FDI inflows for investments in transportation, energy and utility infrastructure. For example, China's ambitious 'Belt and Road Initiative' spanning over 70 countries looks to connect Asia Pacific with Africa and Europe through modern transportation corridors and special economic zones. Such large-scale government projects have significantly driven up the demand for various building materials including structural components like prefabricated I-joists.

Global I-joist Market Challenge - Improper installation techniques

One of the key challenges faced by the global I-joist market is improper installation techniques. While I-joists provide significant benefits over solid timber in terms of strength, lightweight properties, and cost-effectiveness, their structural performance can be severely compromised if they are not installed properly. Common installation mistakes include failing to provide adequate bearing surface, not installing required structural sheathing, insufficient fastening of the I-joist, and not following prescribed spacing and layout as specified in the engineered drawings. This can cause issues like collapse of floors, cracking of finishes, and deflection over the long run. Educating carpenters, builders and DIY consumers about best practices is important but challenging given the complexity of techniques required. Manufacturers continue to work on developing simpler installation guides and training programs to address this challenge and ensure I-joists deliver their promised benefits over the lifetime of the structure.

Global I-joist Market Opportunity - Bridging in Commercial Facilities

One of the significant opportunities for the global I-joist market is its increasing application as bridging material in commercial facilities like warehouses, distribution centers, and manufacturing plants. Compared to traditional solid timber beams, I-joists provide multiple advantages as bridging including higher strength-to-weight ratio, consistent quality, and lower susceptibility to warpage. Their engineered design makes them suitable for bridging over much longer spans ranging between 16 and 30 feet. This allows commercial builders greater flexibility in design and layout of large open floor plans required in industrial and logistics facilities. As infrastructure development and construction activity picks up globally especially in emerging markets, the demand for large commercial buildings is expected to rise significantly. I-joists can help address this demand by enabling rapid construction of facilities at lower costs through their bridging application. Leading manufacturers are actively marketing I-joists for this use to capture new growth opportunities.
