Exterior Continuous Insulation

A continuous layer of rigid insulation is the preferred wall solution for providing the ultimate above-grade wall protection. By insulating the entire exterior wall span – not just the space between wall studs –thermal bridging is minimized and energy efficiency maximized.

DuPont offers a range of high-performance exterior insulation products that provide the following benefits:

  • High, long-term R-value
  • Exceptional moisture resistance
  • Excellent compressive strength
  • Long-term durability and performance
  • Compatible with variety of building types

Exterior Weatherization

Preventing water and uncontrolled vapor from entering through exterior walls is critical for a long-lasting high-performing envelope. Our leading portfolio of complete building envelope solutions offers proven compatibility with our other building envelope components to put you at ease that your structure uses high performing solutions backed by building science.

DuPont has been the industry leader since it invented the building wrap category more than 40 years ago. Today, we’re working with architects, builders and installers on innovative solutions for the next generation of new construction, and renovation of existing buildings.

Exterior Air Sealing

The small air leaks and cracks found in a typical home or building can add up to big energy losses and serious moisture damage. Whether air sealing during new construction or sealing an existing structure, DuPont's range of insulating foam sealants are a quick and convenient solution for closing exterior gaps in your building envelope.

Exterior Insulation and Finish Systems (EIFS) or External Thermal Insulation Composite Systems (ETICS) as they are also known, are proprietary, multi-layered exterior wall systems that are increasingly popular with architects and owners because they improve energy savings, reduce costs and provide tremendous design versatility.

Solutions like DuPont™ XNERGY™ instulation or Styrofoam™ Brand Panel Core Insulation are key to EIF's excellent energy efficiency, durability and moisture resistance.

Using DuPont Performance Building Solutions insulation, architects designing EIFS assemblies are provided with a reliable single-source solution for the air and water-resistive barrier, continuous insulation and exterior wall finish.
