The US air barrier market size was valued at US$ 3,269.13 million in 2022 and is projected to reach US$ 4,283.48 million by 2028. It is expected to grow at a CAGR of 4.6% from 2022 to 2028.

Air barrier is a material designed and constructed to control airflow between a conditioned space and an unconditioned space. These systems should be impermeable to airflow, continuous over the entire building enclosure, able to withstand the forces that may act on them during and after construction, and durable over the expected lifetime of the building. Various advantages of air barriers are resulting in their greater adoption in residential, commercial, and industrial sectors in the US. In residential and commercial buildings, air leakage is a major source of energy waste. As per the US Energy Information Administration, buildings consumed about 40% of the total energy used in the US in 2016. Making buildings tighter through the proper use of continuous air barriers can help significantly reduce this energy usage. The International Energy Conservation Code (IECC), the DOE Zero Energy Ready Home program, and several state energy codes now require the use of air barriers. The strong growth in the residential construction sector in the US is also driving the demand for air barriers. The popularity of fluid-applied air barriers is rapidly increasing, owing to their various advantages such as versatility, ease of application, and effectiveness even on irregular substrates. Hence, the use of fluid-applied air barriers is increasing. This is expected to boost the US air barrier market growth. Further, players' focus on performance improvement of the product is enabling them to launch new and innovative air barriers for their customers. For instance, in October 2020, GCP Applied Technologies added two new products to its air barrier portfolio-PERM-A-BARRIER VPL 50RS and PERM-A-BARRIER VPS 30 membranes. These new air barriers are specifically designed to offer superior protection against the damaging effects of air and liquid water ingress on building structures. This will offer lucrative opportunities for the growth of the air barrier market in the country.

Based on type, the US air barrier market is segmented into vapor permeable and vapor impermeable. The vapor permeable segment held a larger market share in 2021. The use of vapor-permeable air barriers in imparting superior moisture protection for homes has grown significantly. In this regard, permeable air barriers have grown in importance. Moreover, a permeable air barrier combats moisture inflation in extreme cold and mixed climates. These are the factors driving the segment's growth in the forecast period.

The growing construction activities in residential, commercial, and industrial sectors are propelling the growth of the air barrier market in the US. Air leakage in homes can increase heating and cooling costs, cause moisture damage in walls, allow pollutants and debris to collect in wall interiors, and provide openings for insects and rodents to enter. To avoid this, air barriers are highly used in residential construction. Moreover, factors such as high disposable income and shift in consumer lifestyle attract consumers to invest in modern and eco-friendly construction. Residential building construction is the largest US construction market segment. The market for this segment is driven by an increase in government spending on residential construction and a rise in demand for new homes and building improvements. Further, high investments in research and development to produce innovative barriers and insulations, such as cellulose and OSB material barriers, will augment the increase in air barrier sales.
