VAPOR RETARDER. A vapor-resistant material, membrane or covering such as foil, plastic sheeting or insulation facing having a permeance rating of 1 perm (5.7 ´ 10-11 kg/Pa × s × m2) or less, when tested in accordance with the dessicant method using Procedure A of ASTM E 96. Vapor retarders limit the amount of moisture vapor that passes through a material or wall assembly
Vapor barrier is commonly used in the basement on the outside of the wall to keep the ground moisture out of the wall materials. If the wall is existing, and earth is against the outside of the wall, it is not uncommon to apply a retarder to the inside of the wall prior to adding insulation or finish materials.
In cold areas vapor barrier is applied to the wall on the WARM SIDE IN WINTER over the insulation to keep moisture from getting to the insulation and condensing as the air gets colder on the outside of the wall. The building codes actually require this application in most areas.
Hope this helps!

What else can I help you with?
What is the purpose of a basement wall vapor barrier and how does it help in preventing moisture issues in the basement?
A basement wall vapor barrier is used to prevent moisture from seeping through the walls into the basement. It helps by blocking the passage of water vapor, which can reduce the risk of mold growth, dampness, and other moisture-related problems in the basement.
What are the best methods for installing insulation for basement walls to improve energy efficiency and maintain a comfortable temperature in the basement?
The best methods for installing insulation in basement walls to improve energy efficiency and maintain a comfortable temperature include using rigid foam insulation, applying a vapor barrier, sealing any gaps or cracks, and ensuring proper ventilation.
What are the benefits of using basement spray foam insulation for improving energy efficiency and moisture control in a home?
Basement spray foam insulation can help improve energy efficiency by sealing gaps and preventing air leakage, reducing heating and cooling costs. It also helps control moisture by creating a barrier that prevents water vapor from entering the basement, reducing the risk of mold and mildew growth.
What are the benefits of installing a basement floor vapor barrier and how does it help in preventing moisture issues in the basement?
A basement floor vapor barrier helps prevent moisture issues by blocking moisture from seeping through the floor into the basement. This can reduce the risk of mold growth, musty odors, and damage to the basement structure. The barrier also helps regulate humidity levels, making the basement a more comfortable and healthy living space.
What are the best methods for insulating a basement to ensure energy efficiency and comfort?
The best methods for insulating a basement to ensure energy efficiency and comfort include using insulation materials like foam board, fiberglass, or spray foam, sealing any gaps or cracks to prevent air leaks, insulating basement walls and floors, and considering adding a vapor barrier to control moisture. Proper insulation can help regulate temperature, reduce energy costs, and improve overall comfort in the basement.
What are some effective methods for insulating cinder block basement walls to improve energy efficiency and prevent moisture issues?
Some effective methods for insulating cinder block basement walls include using rigid foam insulation, applying a vapor barrier, sealing any cracks or gaps, and installing a drainage system to manage moisture. These methods can help improve energy efficiency and prevent moisture issues in the basement.
What type of underlayment is recommended for a basement floor?
A vapor barrier underlayment is recommended for a basement floor to prevent moisture from seeping through and causing damage.
What is the purpose of a basement drain plug and how does it help in preventing water damage in a basement?
A basement drain plug is used to prevent water from entering a basement through floor drains during heavy rain or flooding. By sealing off the drain, it helps to prevent water damage by keeping water out of the basement and reducing the risk of flooding.
Is there a way to prevent water from seeping into the basement floor?
Yes, there are several ways to prevent water from seeping into the basement floor, such as installing a sump pump, improving drainage around the foundation, sealing cracks and gaps, and waterproofing the basement walls and floor.
Can I repair my leaky basement windows, or must I replace them?
The best thing to do if you want to prevent your basement windows leaking when it rains, is to call in a professional. You can buy home sealing kits but they can be very expensive.
