Building Envelope systems for Durable, Energy-Efficient Homes

Not all building envelope systems are the same. The differences in performance and energy efficiency that can be achieved by using DuPont™ Tyvek® weather barriers and related products can be significant over time.

As a builder, knowing the differences can add value for both you and your clients, whether you are building a single-family home or an apartment complex.

Innovation Inside: Weather Barriers for Energy Efficient Homes

Rising energy costs and increasingly stringent codes and standards are making high-performance, energy efficient homes and commercial buildings a priority.

DuPont Building Envelope systems provide an integrated solution, with science-based products, for the next generation of energy efficient construction.

Commericial Building Envelope Design

An air tight Building Envelope design can be a cost-effective way to reduce long-term operating costs and increase energy efficiency for commercial buildings.

One of the easiest things commercial builders, installers and specifiers can do to significantly increase building performance and lower total operating cost is choose DuPont™ Tyvek® products for the building envelope design, right from the start.

Control Air Leakage For Energy Efficiency And Structural Integrity Building and energy codes and standards are becoming increasingly focused on reducing energy consumption and environmental impact. This makes controlling air leakage in buildings essential. It also creates new challenges – and opportunities – for construction professionals.
Protecting the R-Value Of Insulation DuPont™ Tyvek® air and water barriers help maintain the installed R-Value of insulation by limiting air movement and providing an added layer of water protection.
Why Weather Barriers Are a Must With Exterior Foam Sheathing While exterior foam sheathing acts as a good insulator and can help meet new codes and standards for energy efficiency, it has important weaknesses as a water resistive and air barrier.

DuPont™ Tyvek® weather barriers protect wall systems from water damage and air intrusion that can occur if foam sheathing is used without an additional weather barrier.
Vapor Permeability Protects Walls Against Moisture, Rot and Mold

A premium, high-performance weather barrier has four beneficial and essential functions – air resistance, water resistance, durability during construction, and the right level of vapor permeability.

Vapor permeability is probably the most ignored and least understood of the four. Yet, it can have the greatest impact on how a wall system performs.

Weather Barrier Myths and Facts: From Airtightness to R-Value

Airtightness, insulation and water management are priorities for building professionals. But myths about all three can get in the way of creating residential homes and commercial structures that are more durable, more energy- efficient and less costly to operate.

In this article, DuPont  Building Science experts take on three common myths – and provide building envelope facts for contractors, builders, envelope consultants, and specifiers.

Understanding New Standards for Energy-Efficient Building

Recent updates to energy codes continue the trend towards energy efficient building, with an increased emphasis on minimizing thermal loads and reducing heat flow through the building enclosure.

DuPont Building Scientist Maria Spinu, Ph.D., LEED AP observes that this can have unintended consequences for moisture management as well as the long-term durability of the building.

Choosing the Best House Wrap: Tyvek® vs. Perforated Wraps Choosing the best house wrap is a short-term decision that can have significant long-term effects. Effective air and water holdout can contribute to both structural durability and energy efficiency, while the optimal level of vapor permeability can allow walls to dry more quickly if water does get in, to help prevent mold and rot.
Compare Tyvek® WRB to the ZIP System® Sheathing and Tape DuPont™ Tyvek® weather barriers are trusted by building professionals to provide performance that ZIP System® wall sheathing and tape can’t.
DuPont Building Science Collaborations DuPont building science collaborations with national organizations are part of our ongoing commitment to developing innovative, sustainable construction practices and standards.
A Commitment to Sustainable Buildings

DuPont Building Envelope systems are designed to help meet the growing demand for more sustainable buildings. We continue to create products and processes that pass rigorous criteria for use in buildings designed to use less energy, water and materials.

Innovative DuPont™ Tyvek® weather barriers and other DuPont Building Envelope systems products apply field tested material science to help in the sustainable design of commercial and residential buildings.
