Triangle Crawl Space Solutions uses both a 6 mil material for simple vapor barrier installation and a thicker more durable 12 mil vapor barrier material depending on the budget and needs of the home.
Does mold grow under crawl space vapor barrier?
Moisture from the ground and from crawl space vents combine to create all sorts of problems under your home. This moisture can create mold, mildew, dry rot and allows insects and other pests to thrive. A vapor barrier is key step to reducing this moisture.

Does a hot water heater need to be enclosed?
Water heaters must be surrounded by a certain amount of clearance, or air space, to function properly and safely. A clearance area of 12 inches is required on all sides of a hot water heater. A certain amount of airflow is also required for proper combustion and ventilation.
Should I staple vapor barrier?
Tug and smooth the vapor barrier to ensure a completely smooth surface lacking wrinkles or gaps through which moisture and air may escape, defeating the vapor barrier’s purpose. Staple through the plastic into the sole plate — the horizontal board running under the studs – at bottom.
Is black vapor barrier better than clear?
Black barriers are more effective at stopping moisture evaporation, compared with the clear barrier. The black color hinders the growth of plant seeds that may reside beneath a home’s crawlspace. Plants naturally send moisture into the air, creating more moisture.
What is the difference between vapor barrier and moisture barrier?
Moisture barriers function to help in preventing water from entering inside of the wall cavity. On the other hand, vapor barriers basically prevent water vapor from the interior of the house to filter through the wall and condense on the warm side of the insulation.
Where should a vapour barrier be placed?
Vapor barriers are usually best installed on the side of the wall that experiences the hotter temperature and moister conditions: the inner surface in colder climates and the outer surface in hot, humid climates. In existing spaces, oil-based paints or vapor-barrier latex paints offer an effective moisture barrier.
Can you put vapor barrier on both sides of insulation?
A. Joe Lstiburek, an engineer and principal with Building Science Corp. in Westford, Mass., responds: Installing a vapor barrier on both sides of a wall is never a good idea in any climate.
What side of insulation does vapor barrier go?
warm side

Is Tyvek considered an air barrier?
No, DuPont™ Tyvek® is not a vapor barrier. It is made with unique material science to keep air and bulk water out while allowing moisture vapor inside walls to escape.
Can you use house wrap as a vapor barrier?
For example, House wrap by itself is not an air barrier, it is a vapor barrier. However, IF installed properly, which is rare, with taped seams, bottom, top edges, and no tears, it acts as an air barrier. So primarily it acts as a vapor barrier, but installed properly can do both; vapor barrier and air barrier.
Will water pass through Tyvek?
Tyvek® is unique
DuPont™ Tyvek® weather barriers have a unique structure, with millions of extremely fine pores that resist bulk water and air penetration, but allow water vapor to pass through and escape the building.
