A vapor barrier, also known as a the vapor retarder, is yet another element of insulation. In the areas which are cold the majority of the year the vapor barrier would be installed on the inside of the insulation for the house. The vapor barrier is placed over the exterior of insulation when it is warm. Warm air is attracted towards cold areas which is why the vapor barrier can stop the process from occurring.
