Demand for air and water barriers in the US totaled $7.0 billion in 2024 and is forecast to increase 3.7% per year to $8.4 billion in 2029. Growth will be driven by an increase in building construction activity, most notably rising single-family housing starts, along with a greater focus on energy efficiency and moisture control in a variety of structures.
Air & Water Barriers Are Key to Energy-Efficient Buildings
Demand for air and water barriers in the US will rise due to a combination of stricter building codes, a focus on energy efficiency and sustainability, and rising awareness of moisture control. As energy efficiency and sustainability standards, such as those outlined in IECC and LEED certifications, become more stringent, the need for high-performance air and water barriers that improve airtightness and reduce energy consumption rises. This is further driven by a growing focus on reducing heating and cooling costs, with builders seeking solutions that enhance thermal performance.
Retrofitting and renovation projects are creating new opportunities for these systems as older buildings are upgraded to meet modern energy efficiency and moisture control requirements, especially in commercial real estate.
From Flexibility to Durability, Advances in Barrier Materials Are Changing the Industry
Advances in material technologies for air and water barriers are enhancing their effectiveness, durability, and ease of installation:
- Self-adhered membranes and liquid-applied coatings now offer improved flexibility and strength, creating seamless, waterproof seals that reduce labor costs and installation time.
- High-performance synthetic materials like polyethylene, polypropylene, and synthetic rubber are increasingly used due to their superior durability, UV resistance, and moisture protection.
These innovations have resulted in thinner, lighter products that are easier to handle, more resistant to damage, and more cost-effective for builders, improving overall performance and meeting stricter energy and sustainability standards.
Resilient Structures: How Air & Water Barriers Are Protecting Against Climate Change
As infrastructure and large building projects continue apace, the focus on resilience to environmental factors like climate change and extreme weather is growing. Air and water barriers are essential in enhancing the durability of these projects by protecting structures from moisture infiltration, which can lead to deterioration. These barriers help safeguard buildings and other structures from the impacts of heavy rain, flooding, and temperature fluctuations, all of which are becoming more common due to climate change.
High-performance barriers such as bituminous membranes and rubber coatings are increasingly used in infrastructure to prevent water damage and corrosion. They also improve energy efficiency by preventing air leaks and moisture buildup, contributing to the long-term sustainability and resilience of buildings and infrastructure in urban environments.
Historical Market Trends & Growth Drivers
Shifts in demand for air and water barrier products can vary from year to year and are determined by numerous factors, primarily those related to building construction activity. They include:
-
levels of housing starts, particularly in the single-family housing segment
-
the size and age of the US housing stock
-
interest rates – low interest rates may encourage home and business owners to take out lines of credit often used to fund repair and replacement projects
-
the number and type of commercial buildings erected or repaired in any given year
-
the types of air and water barrier materials most often specified by contractors and other consumers in a particular region of the US
-
the air and water barrier materials originally installed on the surface
Additionally, multiple other variables can affect demand for air and water barriers in a particular year or over a short period of time. Among these are:
-
weather conditions, especially outbreaks of severe weather that can cause widespread damage to roofs (e.g., hurricanes and tropical storms, tornadoes, hailstorms, and winter storms)
-
modifications to state and local building codes
-
changes in the price of raw materials (e.g., asphalt, metal, acrylics, plastics) that can cause the per-square foot or linear foot cost of air and water barrier materials to increase or decrease sharply

Demand by Market
Markets Overview
Air and water barriers are used on buildings and various other structures (e.g., bridges), with demand at the broadest level divided between three large markets:
-
residential buildings
-
commercial buildings
-
infrastructure
The residential market accounts for a greater share of air and water barrier demand in any given year because of the large numbers of new homes – especially single-family homes – that are erected annually. The residential market will continue accounting for the larger share of air and water barrier demand.
Demand for air and water barriers is projected to grow 3.7% annually, reaching a market value of $8.4 billion in 2029:
-
Homeowners and builders will continue to focus on energy performance through airtightness and moisture control, driving demand for air and water barriers like self-adhered membranes and liquid-applied coatings, especially in climates with high humidity or temperature fluctuations.
-
The demand for high-performance building envelopes in commercial buildings to meet energy efficiency and water protection standards will support the use of advanced air and water barriers.
- The need for durable, high-performance barriers to protect against water damage and corrosion in challenging environments (e.g., tunnels, bridges) will increase in the infrastructure segment, with solutions like bituminous membranes and rubber coatings maintaining popularity in infrastructure projects.
