Better building blocks for homebuilding

Alternative to site-built framing from Covestro takes wall panelization to new heights

PUREwall panel
PUReWall™ panels from Covestro offer a cost-effective alternative to site-built framing.

Pittsburgh, January 8, 2018 — Residential builders and panelizers seeking new building technologies that are cutting-edge, cost-effective and energy-efficient should look no further than PUReWall™ panels from Covestro LLC. At the International Builders' Show (IBS), Jan. 9-11, in Orlando, Florida, Covestro will showcase PUReWall™, a high-performance, insulated structural wall panel that takes residential construction to the next level.

Covestro is partnering with the top residential homebuilders and panelizers throughout the U.S. to implement PUReWall™ panels into the residential construction marketplace. The innovative design of PUReWall™ panels replaces traditional exterior sheathing and house wrap with a combination of polyisocyanurate (polyiso) continuous insulation on the exterior and structural spray polyurethane foam (SPF) in the wall cavity.

PUReWall™ panels are manufactured at a panelization facility, in a controlled environment, and installed at the construction site. This alleviates jobsite workforce bottlenecks, produces less waste, requires less wood use and results in a faster framing time for builders.

PUReWall™ panels also provide the following advantages:

  • Increased R-value and decreased air infiltration, contributing to a higher Home Energy Rating System (HERS) index score.
  • Produces a wall assembly that passes ASTM E331 with an integrated weather-resistant barrier featuring polyiso board with coated glass facers on both sides and taped joints backed by at least 1.5 inches of closed cell spray foam.
  • Scalable to provide thermal performance in the wall assembly as part of an overall building envelope approach making PUReWall™ panels suitable to use in a Net-Zero capable structure
  • Adaptable to meet all Climate Zone U values in IRC 2015
  • Adaptable to meet California’s Title 24 energy efficiency code requirements
  • Has minimal potential for condensation in the wall assembly in both hot/humid and cold climates versus conventional wall assemblies


PUReWall™ panels are available in a range of configurations to meet advancing building codes in any U.S. climate zone, with demonstration panels for each located at the Covestro booth:

  • PUReWall™ 60: U-0.060 (R-17) for Climate Zones 1-5 in IRC 2015 [2x4 construction with framing 16 or 24” on center (o.c.), 1” polyiso continuous insulation, 1.5” spray polyurethane foam insulation]
  • PUReWall™ 45: U-0.045 (R-22) for Climate Zones 6-8 in IRC 2015 [2x4 construction with framing 16 or 24” o.c., 2” polyiso, 1.5” spray polyurethane foam insulation]
  • PUReWall™ T24: U-0.052 (R-20) for California Title 24 requirements [2x4 construction with framing 16 or 24” o.c., 1.5” polyiso, 1.5” spray polyurethane foam insulation]
  • PUReWall™ 30: U-0.030 (R-33) for beyond code wall assemblies for aspirational building designs, such as Net-Zero ready [2x6 construction with framing 16 or 24” o.c., 2” polyiso, 2.0” spray polyurethane foam insulation and fiberglass batt]
