One Precision Assemblies (OPA) is an airtight and weatherproofed shell solution adaptable to all residential single-family designs. The shell is panelized and prefabricated in factory within one to two weeks, and meticulously raised on the job-site by CertainTeed’s team within one or two days. Elements of the panels includes framing, sheathing, insulation, weatherproofing wrap and membrane, windows and exterior finishing.
Using OPA will help builders:
- Build energy-efficient and durable homes, while simplifying their trade management,
- Build in winter and cope with unpredictable weather,
- Improve site safety and
- Help reduce expensive re-work and vandalism.
The CertainTeed team will adapt the shell to the desired residential project design and provide builders with an adequate and permittable construction documents. The company’s digital tools will convert the overall shell design into a suite of custom-sized wall, roof and floor panels, as well as stairs, optimized for transportation and ease of assembly on the job-site.
The materials, details, and composition of the global assembly has been rigorously designed by CertainTeed building scientist team. The ONE PRECISION ASSEMBLY shell has been conceived to ensure code-compliancy, high-performance handling of thermal energy, air, water and water vapor in climate zones 4 through 8. This performance is ensured through algorithmic analysis, digital manufacturing, strict assembly methods, and a robust quality control system. The impact of this comprehensive approach yields faster production and on-site assembly times, dramatically reduced waste, increased quality, greater energy efficiency and weather resilience, and an aesthetically compelling home, all with the CertainTeed products.
