Vapor Barrier puts a barrier between moisture and the sub-floor of your home

What is a Crawl Space Vapor Barrier and when would I use one?

Vapor barrier is also known as poly or moisture barrier. Most building codes now require vapor barrier in the crawlspace. 40% of moisture comes from the ground. Therefore, the plastic is putting a barrier between the moisture that comes from the earth and the sub floor of your home. Poly is intended to retard the migration of moisture in your crawlspace.

What does Mil stand for and what’s the difference between them? What does reinforced mean?

Any vapor barrier that is not reinforced refers to the thickness of the plastic. Anything that is reinforced beyond 12 mil refers to the thickness of the fiber and material.

Why is the 6 Mil clear and the 12 Mil a solid color?

12 Mil is a stronger plastic and will last longer.  The difference in color you see from various 12 mil vapor barriers on the market only differs by who manufactures it and has no practical application.  When installing 12 Mil, you should white side facing up and color to ground.

Vapor Barrier Accessories

Vapor Barrier Stakes mean less work to keep the vapor barrier from moving during install versus using common insulation stakes/tiger teeth.

Use Butyl Tape and Christmas Tree Fasteners if you are encapsulating and bringing the vapor retarder up the wall or pillars.

Use Capped Vapor Barrier Stakes for a finished look and easier installation of the stakes. The Buttons are great for helping pound the stakes with a rubber mallet.
