Exterior Walls

Solutions for the Entire Wall Envelope

Dow exterior wall solutions give you a systematic approach that works for your entire building envelope. Innovative yet easy-to-install, our exterior insulations systems and sealants are helping architects and contractors deliver high-performance buildings of all types.

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.

Dow 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 vapor from entering through exterior walls is critical for a long-lasting high-performing envelope. As part of a systematic approach to wall building, Dow’s weatherization solutions are designed to integrate with our portfolio of exterior wall solutions, contributing to your entire building envelope.

For buildings using continuous exterior insulation, we offer application-specific weatherization products to effectively keep moisture from entering the building envelope. LIQUIDARMOR™ is a liquid flashing solution for sealing board joints as well as wall punctures like doors, windows and piping.

When continuous, rigid insulation is not an option or is not enough because a secondary water-resistive barrier is desired, house wrap solutions from Dow are your best choice. WEATHERMATE™ House wrap is a woven, perforated, polyolefin-based house wrap that is both tough and tear resistant and can be installed over non-insulated sheathing in residential construction to reduce air and moisture intrusion.

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, Dow’s range of insulating foam sealants are a quick and convenient solution for closing exterior gaps in your building envelope.

EIFS & ETICS

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 DOW™ XNERGY™ rigid insulation or STYROFOAM™ Brand Panel Core Insulation are key to EIF's excellent energy efficiency, durability and moisture resistance.

Using Dow 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.
