Air Barriers for Commercial Buildings

Protect Your Building from the Start

The goal of every builder is to create a sturdy, safe building that will serve its occupants well for many years to come. From the foundation to the roof and everything in between, every component affects long-term durability and energy performance. One of the most effective ways to protect a commercial structure from the elements is to ensure the building envelope is tight, well-protected, and built to last. That’s where Cullen Insulation air barrier services come in.

We help ensure your commercial building is energy-efficient and resilient by installing a high-performance air barrier system that supports an airtight building enclosure, moisture protection, and long-term efficiency.

The Importance of an Air Barrier

Two of the biggest threats to a new building are moisture and uncontrolled air leaks. Moisture from rain and humidity can lead to mold, mildew, and structural damage over time, while air leaks reduce commercial building energy efficiency and create comfort issues. A properly installed air barrier, whether it is a fluid-applied air barrier, a self-adhered air barrier, an air-and-vapor barrier, or a vapor-permeable air barrier, helps prevent air leakage and resists water intrusion into your wall cavity.

At Cullen, we install a full range of products, including air barrier membranes, air barrier transition membranes, water resistive barriers, and permeable and non-permeable system. . We also provide detailed air barrier penetration sealing and use proven air barrier sealant products to ensure complete continuity. Our team selects the best solution based on your building’s design, climate needs, and code requirements.

Benefits of an Air Barrier

Improved Energy Efficiency

A high-quality building air barrier works with insulation to reduce air infiltration rates and improve air infiltration control. This results in better-performing insulation systems and greater energy savings.

Keeps Buildings Dry

An air barrier keeps water out, helping maintain a dry, comfortable building year-round. A dry wall cavity also ensures insulation remains effective in the long term.

Lower Energy Bills

A more airtight structure delivers measurable efficiency gains, resulting in lower operating costs for commercial property owners.

Moisture Control

A strong air- and vapor-barrier system helps block moisture migration and prevent mold within the wall assembly.

Adds Safety and Durability

Applying a continuous exterior air barrier protects the building envelope, reduces long-term maintenance issues, and helps safeguard electrical systems from water exposure. The result is stronger, more reliable commercial weatherproofing.
