Does Exterra Qualify as My Air Control Layer?

When it comes to creating an effective building envelope, ensuring that every layer serves its intended purpose is crucial. One common question is whether Halo Exterra can serve as the air control layer for your project?

Short Answer: No

Halo Exterra does not qualify as an air control layer under current building code standards. While Exterra excels in many areas, competitors’ products that meet air control requirements may appeal to those prioritizing a single-product solution.

Here’s a breakdown of why Halo Exterra doesn’t meet this need:

  • Air Permeance: Exterra’s air permeance exceeds the acceptable threshold outlined in the building code. For a product to act as an air control layer, it must sufficiently restrict the flow of air through it.
  • Perforations: Exterra’s perforations are designed to allow moisture to escape outward, helping the building dry efficiently. However, these same perforations prevent the product from serving as an air barrier.

What Does This Mean for Your Project?

While Exterra is an excellent solution for moisture management and other critical applications, it’s essential to pair it with a dedicated air control layer that meets code requirements. This ensures your structure is energy-efficient, durable, and compliant with regulations while maintaining proper moisture flow.

Wrapping It Up

Halo Exterra is a high-performing product tailored for specific purposes, but it’s not designed to act as an air control layer. For a compliant, efficient system, confirm that each material you choose aligns with its intended function. The right combination of products is key to a building envelope that performs at the highest level.
