In the latest edition of Modular Home Source’s newsletter, which reaches over 3,000 professionals in the construction industry weekly, I posed a forward-thinking question:
“Which type of wall systems will most modular factories use in 20 years?”
The responses painted a diverse picture of the future of modular construction, highlighting trends and preferences that are likely to shape the industry for decades to come.
Wood Studding – Thermal Break Panelized – 31.6%
Topping the survey, with 31.6% of respondents, is wood studding with thermal break panelized systems. This choice reflects a growing emphasis on energy efficiency and sustainability. Thermal break panelized systems are designed to minimize heat transfer through the walls, significantly improving a building’s insulation performance. This not only enhances energy efficiency but also reduces heating and cooling costs, making it an attractive option for both builders and homeowners.

As environmental concerns continue to rise, the adoption of these systems is likely to accelerate. The construction industry is increasingly focused on reducing its carbon footprint, and thermal break panels align well with these sustainability goals. Their ease of installation and compatibility with various architectural designs further enhance their appeal, positioning them as a likely standard in future modular construction.
Wood Studding – Conventional Panelized – 26.3%
Closely following, 26.3% of respondents believe that conventional panelized wood studding will remain prevalent. This traditional method has been a cornerstone of construction due to its reliability, cost-effectiveness, and ease of use. Conventional panelized systems offer a balance between structural integrity and affordability, making them a staple in the industry.

While innovation is critical, the enduring popularity of conventional wood studding indicates that tried-and-true methods still have a place in the future landscape. The simplicity and familiarity of these systems mean they will continue to be favored, especially in regions where cost constraints and building codes favor conventional materials.
SIP Wall Panels – 16.4%
Structural Insulated Panels (SIPs) garnered 16.4% of the vote, reflecting their growing acceptance in the modular construction sector. SIPs are praised for their excellent insulation properties and structural strength, combining a rigid foam core sandwiched between two structural facings, typically oriented strand board (OSB). This composition offers superior thermal performance, reducing energy consumption and enhancing comfort.
SIPs are also known for their quick assembly, which can significantly shorten construction timelines—a critical advantage in the modular industry. As building regulations continue to tighten around energy efficiency, SIPs are likely to see increased adoption, providing a robust solution that meets both regulatory and consumer demands.
Light Gauge Steel – 15.2%
With 15.2% of respondents favoring light gauge steel, this material is seen as a promising alternative to traditional wood-based systems. Light gauge steel is non-combustible, resistant to pests and rot, and offers superior strength-to-weight ratios. These properties make it an attractive option for constructing durable and resilient buildings.

The use of steel also aligns with trends towards prefabrication and automation in construction, as steel components can be precisely manufactured offsite. However, the higher cost of steel and the need for specialized skills in handling and assembly are challenges that need to be addressed for broader adoption.
CLT Wall Panels – 7.9%
Cross-Laminated Timber (CLT) wall panels, chosen by 7.9% of respondents, represent a cutting-edge approach in modular construction. CLT is a sustainable, high-performance building material made from layers of solid wood boards glued together at right angles. This configuration provides exceptional strength and stability, making it suitable for both residential and commercial buildings.

CLT panels offer numerous benefits, including reduced construction times, lower environmental impact, and the ability to sequester carbon. Despite its relatively low percentage in the survey, the increasing interest in sustainable construction practices could see CLT gaining more traction in the future.
Plasticized Insulated Panels – 2.6%
The least favored option, with 2.6% of the vote, was plasticized insulated panels. While these panels offer benefits such as excellent moisture resistance and insulation properties, they face significant competition from more established materials. Environmental concerns regarding the use of plastics in construction and the availability of more sustainable alternatives may also limit their adoption.

Modcoach Note
The survey results underscore the evolving landscape of wall systems in modular construction. As the industry advances, a blend of traditional and innovative materials will likely define the future. Wood studding, both thermal break and conventional panelized, will continue to be mainstays, while SIPs, light gauge steel, and CLT panels represent the forefront of innovation, addressing the demands for sustainability, efficiency, and resilience.
Understanding these trends is crucial for industry stakeholders as they plan for the future. By staying ahead of these developments, modular factories can position themselves to meet the evolving needs of the construction market, ensuring their growth and success in the decades to come.
