Vapour Diffusers And Vapor Barriers - Are They The Same?

 

There has been so much confusion in home improvement industry, especially with the terminologies used in it. In the industry of basement waterproofing, there's one main objective and it is to keep the water out. The required technology in the basement is somewhat similar but the thing is, it's different from the type of technology that is used for home construction.

 

The term that is thrown frequently is the vapour barrier however, there are so many property owners who are confused with what a vapour barrier is from vapor barrier company Raleigh NC. In the following paragraphs, I will try to give a brief description of each to have a better understanding between the two.

 

Vapour Diffuser

 

Anything can almost be used as a vapour diffuser including vinyl siding and plywood. It is slowing down the transfer of moisture from the outside to inside. Most of the time, the conventional plastic sheeted vapour diffusers are put up on the perimeter of the home walls when constructing it. This is protecting both the interior joists, crossbeams and the insulation from other elements that may penetrate the siding.

 

The vapour differs are only recommended for the above grade construction as they're not specifically designed to deter moisture 100 percent. Perms or the rate in which water vapour may move through the object on the vapour diffusers usually range anywhere from 1 to .4.

 

Vapour Barriers

 

This is different from the diffusers from http://www.cleanenvisions.com/open-close-vents-raleigh.php as their design is specific to have better perm rates. A common vapour barrier that is used for waterproofing may range anywhere from .014 to .0015 which is pretty amazing. Keep this in mind, the lower the number, the better the protection that it can provide. What this mean is, the barrier is a lot stronger in defending towards the transfer of water vapour. They are pretty strong that common installation method is done differently when finishing.

 

The vapour barriers ought to be attached to the wall's foundation and directed to the drain system. Otherwise, the water will end up on the floor, which will defeat the entire purpose of waterproofing it.

 

Most of the time, contractors use vapour diffusers in the basement to be able to stop the water. Another issue that arise is the fact that some contractors are installing in front of insulation, which may result to major problems when flooding take place. Water might be trapped behind the diffusers and render all insulation to be useless and ruin the studs. This is the main reason why vapour barrier should be installed.
