On paper, the notion of modular, offsite construction makes a lot of sense. Who wouldn’t want to streamline the building process while minimizing labour costs?
In practice, however, prefab, pre-cut and panelised components remain something of an outlier, as the homebuilding industry still overwhelmingly Favors on-site stick construction. In fact, offsite construction featured in just 3% of single-family builds in 2024 (down from 7% in 2023).
So, what’s the holdup? Factors like zoning laws, uncertain demand, perceptions regarding quality and startup costs required to shift production methods have been named as deterrents.
Industry inertia and attitudes certainly play a role as well. The “we’ve always done it this way!” mentality can make change difficult and thwart fresh approaches. But there are some in the LBM world determined to make modular more mainstream.
Saint Gobain subsidiary CertainTeed is one such case. Below, Dennis Michaud, the company’s managing director for offsite solutions & residential resiliency, shares insights into the company’s offsite efforts and plans to tap more market share.
Q: Can you describe CertainTeed’s current modular offerings and initiatives?
Michaud: CertainTeed supplies modular and manufactured housing manufacturers with a comprehensive portfolio of building envelope solutions—including roofing, siding, insulation and gypsum wallboard, as well as the NO-COAT PRO drywall corner system and the Volu-Matic suite of industrial insulation blowing equipment.
Beyond supporting modular and manufactured housing, CertainTeed has also commercialized its own panelised solution, ONE PRECISION ASSEMBLIES (OPA). Instead of shipping entire modules, OPA delivers precision-engineered floor, wall, and roof panels that are assembled on-site.
This solution reduces build times for developers and homebuilders by up to 50% compared to traditional construction. Each assembly is manufactured in a controlled environment to ensure quality and consistency and integrates CertainTeed’s full portfolio of materials under one manufacturer and one warranty.
Originally introduced in 2023 in the Northeast, OPA expanded into the Southeast in 2025 and is now available in 25 states. With projected growth of more than 300% in the coming year, OPA is demonstrating strong builder demand and accelerating market momentum. Its versatility makes it an ideal solution for single-family homes, low-rise multi-family projects, and even challenging infill lots, giving builders and developers the flexibility to meet diverse market needs.
Q: Moving forward, what’s next for the company in terms of offsite offerings?
Michaud: CertainTeed sees offsite construction—including modular, panelised and manufactured housing—as a powerful tool for improving productivity, affordability and resilience in the construction industry.
We will continue to enhance modular-friendly solutions that accelerate roofing, insulation and drywall installation, along with introducing new siding materials designed to increase durability during transportation of modular and panelised units.
On the ONE PRECISION ASSEMBLIES side, our focus is on expanding geographic reach with regional scaling to meet demand in high-growth housing markets. This expansion will allow us to serve more builders and developers with a system that delivers speed, quality and flexibility for diverse housing types.
Q: What are some big trends you’re seeing in the business right now, and what do you see rising in importance in 2026?
Michaud: The construction industry is being shaped by three major trends: a persistent labor shortage, a significant housing deficit, and the urgent need to deliver resilient housing solutions that can withstand increasingly severe weather events.
These challenges are pushing builders and developers to seek methods that reduce jobsite complexity, accelerate timelines and ensure long term durability.
Looking ahead to 2026, resilience will become even more critical. Homes will need to be engineered for strength and adaptability to meet the demands of climate extremes and evolving building codes. Solutions that combine precision manufacturing, moisture management and high-performance materials are positioned to help meet these priorities.
Q: What trends are you seeing in modular building in particular?
Michaud: Growth in modular and panelised building is strongest in regions facing acute housing shortages and high labour costs, where speed and efficiency are critical.
Builders are increasingly prioritizing high-performance materials that deliver durability and energy efficiency, along with assemblies that provide superior thermal performance—often in the range of R-20 to R-60.
Technologies such as precision manufacturing and moisture-managed assemblies are emerging as key differentiators, helping ensure consistency, quality and long-term resilience.
Q: In your view, what are some of the biggest obstacles to offsite building in the U.S.?
Michaud: Some of the biggest obstacles include perception and education, as many builders still view offsite construction as niche or costly despite its proven efficiencies.
Also, regulatory complexity, with varying local codes slowing adoption.
The skilled labor gap is an issue as well, because even with offsite solutions, experienced crews are still needed for assembly and finishing.
Q: What sorts of technologies is CertainTeed using in its offsite segment?
Michaud: In engineering and manufacturing ONE PRECISION ASSEMBLIES, CertainTeed uses advanced 3D CAD and computer-aided manufacturing software to translate builders’ designs into precision-engineered panels. Production utilizes automated cutting, framing, nailing and insulation systems to ensure accuracy and consistency.
Q: How has CertainTeed been mitigating the impact of tariffs, and what do you see on this front in 2026?
Michaud: Global trade is an important part of the modern economy, and CertainTeed complies with all trade rules in the countries where we operate, including tariffs.
Our parent company, Saint-Gobain, globally has a country-focused approach for sourcing materials and resources from within our region as part of our business model. Over the past three years, we’ve made significant investments in North America—expanding operations in the U.S. and Canada and acquiring companies that strengthen our regional supply chain.
With more than 160 manufacturing facilities across the region, we remain committed to continuing operations as normal and supporting the strong demand for housing.
