PUReWall™ – What Builders Need to Know

Covestro understands, and that’s why we’ve spent the last 5 years developing, testing, tweaking, and ultimately, proving PUReWall™ technology. And, we have proactively addressed some your most important questions:
-
Anywhere in the United States! By simply varying the insulation thickness, PUReWall™ is easily configurable to meet or exceed code requirements in North American climate zones 1 – 8, and can even meet net zero-ready requirements.
-
Yes! PUReWall™ is structurally comparable to a traditional wood stud / OSB sheathing wall assembly in racking strength. With appropriate structural connectors, PUReWall™ can be engineered for use in all regions of the United States, including areas with high wind and seismic concerns.
-
It’s typically more cost-effective and energy-efficient. The continuous insulation on PUReWall™ acts as both the exterior sheathing and as a weather-resistant barrier, replacing the traditional sheathing and house wrap. It is highly energy-efficient, and when used in conjunction with spray polyurethane foam, creates a robust, high performance wall using only a 2x4 stud with 24” on center placement.
-
Yes. Through the use of polyiso continuous insulation on the exterior and spray polyurethane foam between the studs, PUReWall™ is scalable to meet current energy codes, including requirements for continuous insulation. PUReWall™ can be designed to perform well beyond existing building codes, making it a good fit for net zero and passive home designs.
-
Per linear foot, the cost of PUReWall™ is typically comparable to or lower than a traditional panelized wall assembly. This is possible because PUReWall™ has components that serve multiple purposes – such as structure, insulation, and barrier control layers – which allow it to eliminate common building materials in the wall assembly.
