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 inhabitants well for many years to come. There are many things that go into building a commercial building, from its foundation to its roof and everything in the middle. And it’s important to protect that building from the harsh elements that it will encounter over its lifetime. That’s where Cullen Insulation comes in.

We’re here to ensure your commercial building is energy efficient and resilient in a variety of ways, including the addition of an air barrier for your building’s exterior.

The Importance of an Air Barrier

Two of the biggest threats to a new building are moisture and air leaks. Moisture from rain and humidity can lead to mold and mildew and damage a building over time, while air leaks diminish the building’s energy efficiency. An air barrier, either self-adhered or fluid applied, helps prevent air leaks and stop the water infiltration into your building’s wall cavity.

At Cullen, we install a full range of air barrier products including fluid applied, self-adhered, permeable, and non-permeable. We make sure you get the best product that has the best fit for your building.

Benefits of an Air Barrier

The importance of applying an air barrier to your commercial building project can be seen in the many benefits it brings:

Improved Energy Efficiency

An air barrier works in tandem with a building’s insulation to help insulation work at its best. It also improves energy efficiency by working to block air leaks.

Keeps Buildings Dry

An air barrier keeps water out so the building can stay dry and comfortable throughout every season. It also helps keeps insulation dry and effective.

Lower Energy Bills

A more energy-efficient building will mean lower energy costs.

Moisture Control

An air barrier helps keep moisture and mold out of the wall cavities of the building.

Adds Safety and Durability

Wrapping a building with an air barrier protects the integrity of the building and its overall durability and safety. It helps prevent electrical components from getting wet, which can cause safety hazards.
