What are the requirements for vapor barriers?
If vapor barriers are warranted by local building practices and code recommendations, keep the following practices in mind: Buildings should meet ASHRAE standards 62.2 or 62.1 for proper ventilation before being sealed by complete vapor barriers.
Do vapor barriers work to block heat transference?
During the energy crisis of the 1970s, a prevailing belief took root where it was thought that tightly sealing walls and ceilings with a vapor barrier was essential to blocking heat transference and reducing energy costs.
How does a vapor barrier work in a basement?
A vapor barrier is useful for keeping moisture from making its way into a basement, keeping mold and water damage at bay. Get the inside scoop on these moisture barriers and find out how they can help protect your basement.
Do I need a vapor retarder after insulation?
After the insulation is in place you will want to add a vapor retarder, sometimes called a vapor barrier, if you need one. Not every wall does. A vapor retarder is a material used to prevent water vapor from diffusing into the wall, ceiling or floor during the cold winter.
Why do concrete slabs need a vapor barrier?
The primary reason is that adjacent structural concrete members often need to obtain a concrete-to-concrete bond with the slab for effective load transfer (among other reasons). A vapor barrier can interfere with this if not properly located.
What type of tape is used for a vapor barrier?
For Stego Wrap Vapor Barrier installations, Stego recommends using STEGOTACK TAPE, a double-sided a dhesive strip which can bond Stego Wrap to concrete, masonry, wood, metal and other surfaces. This super-sticky tape will keep Stego Wrap bonded to the vertical wall after concrete placement, achieving a vapor barrier seal as required by ASTM E1643.
Why use a vapor barrier?
The goal of vapor barrier strategies is to prevent moisture from collecting and corrupting building materials. Improperly installed, a vapor barrier may actually trap moisture inside a wall, while a wall that is more porous can breathe effectively and be less susceptible to long-term moisture problems. This condition is especially problematic ...
Why are vapor barriers important?
In circumstances where conditions inside a home or office are much different than outdoor conditions, water vapor is likely to move through wall cavities and can get trapped inside, and a well-installed vapor barrier is recommended. Vapor barriers can also be important for certain rooms where moisture levels are especially high.
What was the purpose of sealing walls and ceilings with a vapor barrier?
During the energy crisis of the 1970s, a prevailing belief took root where it was thought that tightly sealing walls and ceilings with a vapor barrier was essential to blocking heat transference and reducing energy costs.
What is the perm rating?
To assist builders in controlling moisture, various building materials are rated according to permeability and are assigned a perms rating. A variety of rating systems are in use, but one common one is the U.S. permeability system. Impermeable materials are those rated at less than 1 U.S. perms.
What is the ASHRAE standard for ventilation?
Buildings should meet ASHRAE standards 62.2 or 62.1 for proper ventilation before being sealed by complete vapor barriers. Modern homes or offices that are tightly sealed in order to be highly energy efficient should also have air-to-air heat exchangers or other methods of ensuring a good exchange of fresh air.
Can you use a vapor barrier in a home with brick?
For example, the recommended vapor barrier in a home or office in a humid southern climate built with brick varies greatly from creating a vapor barrier in a cold climate in a home built with wood siding. Always refer to current local code recommendations when deciding if and how to install vapor barriers. Avoid adding interior vapor barriers ...
Do you need a vapor barrier in a greenhouse?
Most authorities recommend vapor barriers in certain situations: In areas with high humidity—such as greenhouses, rooms with spas or swimming pools, and bathrooms—vapor barriers are often recommended. Consult building inspection offices for local recommendations.
What is vapor barrier?
The material is stapled to the frame of a basement wall before it is finished with plaster or drywall. A vapor barrier is also helpful to keeping a basement insulated and warm.
Does a vapor barrier stop water from entering the basement?
While a vapor barrier won' t stop moisture from making its way between the foundation walls and the actual barrier, it will help prevent water from coming into the basement. This, of course, helps to dissipate moisture and mold – two things that no one wants to see in a basement. You may also want to consider choosing insulation ...

What is vapor retarder?
A vapor retarder is a material used to prevent water vapor from diffusing into the wall, ceiling or floor during the cold winter. Whether or not you need a vapor retarder hinges on three main factors your climate, your home and the location of the wall you're insulating.
What to do after studs are in place?
Your first job after the studs are in place is to fill those walls with insulation. If you are not sure if you need insulation in your walls follow along with this flow chart. After the insulation is in place you will want to add a vapor retarder, sometimes called a vapor barrier, if you need one. Not every wall does.
Do you need a vapor retarder in the winter?
If you live in a mixed climate – hot and humid with several heating months in the winter, you probably need a vapor retarder. Specifically, if you live in climate zones 4C (marine), 5, 6, 7 and 8. Not sure your climate zone?
Can a vapor retarder be used in a wall?
In certain climates vapor retarders can be a vital part of the wall construction. However incorrect use can lead to additional moisture problems. Consult an insulation professional in your area if you are unsure where or how to install a vapor retarder or consider a vapor retarder that provides some degree of additional flexibility, like a smart vapor retarder. A smart vapor retarder is able to adapt its permeability to allow the wall to dry should moisture get trapped in the wall cavity.
