A reader poll returns a range of opinions on which types of components will be used by modular factories.
“Which type of wall systems will modular factories use in 20 years?” A couple of months ago, I posed that question to the readers of my blog: ModularHomeSource.com.
The responses paint a diverse picture of the future of modular construction, highlighting trends and preferences that are likely to shape the industry for decades to come. Here are the results, ranked most to least popular:
#1: Wood Studding – Thermal Break Panelized – 31.6%
Topping the survey, with 31.6% of votes, is panelized systems built with wood studs that include thermal breaks. This choice reflects a growing emphasis on energy efficiency and sustainability. Thermal break panelized systems are designed to minimize heat transfer through the walls. Not only do they enhance energy efficiency, but they also reduce heating and cooling costs, making them 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.
#2: Wood Studding – Conventional Panelized – 26.3%
Coming in a close second, 26.3% of respondents predict that conventional panelized wood studding will continue to dominate the industry. This method has been a cornerstone of the industry because of its reliability, cost-effectiveness and ease of use. Conventional panelized systems offer a balance between structural integrity and affordability.
This result tells me that, while innovation is critical, the enduring popularity of conventional wood studding as a tried-and-true building method secures it a place in the future landscape. The simplicity and familiarity of these systems mean they will continue to be favored in many places, especially in regions where cost constraints and building codes favor conventional materials.

#3: SIP Wall Panels – 16.4%
Structural Insulated Panels (SIPs) garner 16.4% of the vote, reflecting a growing acceptance in the modular construction sector. SIPs have received wide praise for their excellent insulation properties and structural strength. Comprised of a rigid foam core sandwiched between two structural facings, typically made from oriented strand board (OSB), this composition offers superior thermal performance, reduced energy consumption and enhanced 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.
#4: Light Gauge Steel – 15.2%
With 15.2% of respondents favoring light gauge steel, this material is 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 in a factory setting. However, the higher cost of steel and the need for specialized skills in handling and assembly are challenges that need to be addressed before this material gains wide adoption.
#5 CLT Wall Panels – 7.9%
Although just 7.9% of respondents chose Cross-Laminated Timber (CLT) wall panels, they represent a cutting-edge approach to modular construction. CLT is a sustainable, high-performance building material made from layers of solid wood boards glued together at right angles, a configuration that 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.
#6: Plasticized Insulated Panels – 2.6%
The least favored option, with a mere 2.6% of the vote, is plasticized insulated panels. While these panels offer 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.
The survey results underscore the evolving landscape of wall systems in modular construction. They indicate that, 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.
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.
