Which Vapor Barriers Do We Most Commonly Install?
6 Mil
Viper 10 mil
Viper 16 mil
What’s the difference?
The 6 mil vapor barrier is pinned to the ground to support with an overlap on each seam. The viper 10 mil and 16 mil vapor barriers are wrapped up the foundation columns and 12 inches up the foundation wall, providing optimal coverage. The viper 10 mil and viper 16 mil barriers are also made of a heavier-duty material and come with a 25-year manufacturer warranty.
NOTE: The viper 10 mil vapor barrier is now known as the viper 12 mil. It has re-classified higher and is even more sufficient.
Did you know the viper 16 mil vapor barriers we install are stronger than a string reinforced 20 mil vapor barrier? Check out the specification sheet below.
As you can see the viper 10 mil and 16 mil vapor barriers have a stronger tear resistance, puncture strength and best permeability rating. The lower the PERM RATING the better the vapor is at stopping the flow of water.
THE WINNER…
The Viper 16 Mil Vapor Barrier! This heavy-duty barrier provides optimal coverage and is the strongest out of all the barriers.
