7 Factors to Consider When it Comes to Under-Slab Vapor Barrier Placement
The Secret Below-Slab Ingredient for Building an Energy-Efficient Home
Redevelopment Can Start With an Effective Vapor Mitigation System
Brownfields historically have been some of the most daunting development projects on the construction landscape. As that landscape expanded, it was much easier to simply move to new areas of development and ignore sites that involved some level of liability, contamination, assessment, cleanup, government regulators, and more. For generations, brownfields have been not just literally – but figuratively – toxic to communities.
The challenges may seem overwhelming, but the financial, social and environmental benefits to redeveloping brownfields are immense.

Despite its cost being measured in mere cents per square foot, project designers, contractors and building owners often disregard a high-performance under-slab vapor barrier. Yet, failing to use this vital material may be the best illustration in the construction industry of “a penny wise and a pound foolish” – unnecessarily risking costly consequences and potentially years of legal squabbling over liability.
Here are 10 critical reasons why you should always use a high-performance vapor barrier, no matter the project:
We have all probably heard of or endured a personal connection to a familiar story: the victim of lung cancer who “never smoked a day in their life.”
For starters, is it Class I or Class 1? Fun fact: it’s actually Class I. I get asked by both homeowners and contractors alike what a Class I vapor retarder is. If you’ve been researching a DIY crawl space encapsulation project, it is possible you’ve stumbled across this reference as well. In this blog post I’ll answer what a Class I vapor retarder is, but I’m also going to use this space to explain why a Class I vapor retarder, although referenced in code as a threshold, may not be satisfactory for your project. To get you started on the right foot, we’ve made it easy for you to look-up the current version of code governing your jurisdiction.
