Debate surrounds the necessity of vapor barriers in construction, but one fact is clear: the systems beneath your building need protection. Exposing HVAC, wiring, or plumbing to moisture invites problems that can be prevented with a vapor barrier.
Here are three key reasons why a vapor barrier under your slab is essential for protecting your project’s hardware:
- Moisture Control: Moisture belongs in the soil, but wet climates like the Pacific Northwest or the swampy portion of the Southeast can make keeping the moisture there a challenge. A vapor barrier creates a shield between the ground and your building, preventing moisture intrusion and promoting the longevity of your project.
- Protecting Metal Systems: HVAC systems, often found in basements or the utility center of structures, are vulnerable to rust and corrosion from water. Even galvanized or coated metal isn’t immune. A vapor barrier eliminates this threat and ensures that the HVAC unit functions properly & protects against other potential issues such as burst pipes and reduced water pressure.
- Electricity and Water Don’t Mix: Electrical systems under a building are at risk from moisture as well, which can lead to costly electrical issues. While most of this wiring is protected by a conduit or plastic sheathing, moisture can still enter through joints or connectors, so we recommend the use of a vapor barrier to prevent these problems.
Now that we’ve covered keeping your building safe, let’s talk about the people inside. Here are two reasons why a vapor barrier is essential in keeping a building’s inhabitants safe:
- Health Hazards: Excess moisture encourages mold, mildew, and humidity inside. This can lead to numerous health issues and bad odors and wreak havoc on HVAC units. A vapor barrier ensures a dry and healthy environment.
- Blocking Toxic Gasses: Dangerous gasses like radon and methane can seep into buildings through the ground. Vapor barriers block these harmful substances, keeping your space safe.
No matter how you put it, vapor barriers are a necessity for today’s projects if you’re working in a high moisture environment. Learn more about vapor barriers here.
