Homes are constructed better these days in most cases than they ever have been before. The materials that are used are safer and many home builders are trying to use products that are considered green by environmentalists. These green products are very important to the future of our planet and the environment. Not only are homes being made greener and better, they are also being built with products that will help protect them for many years from things like water damage and mold.
Mold can be one of the biggest enemies to a home and mold starts with water. It can be a dripping leak that is exposing a porous material like wood or dry wall to water. Mold and rotting can get started from many kinds of problems in and outside of the home. One of the easy ways a home can develop water damage is from too much moisture. This is when there home has too much moisture in the air. Moisture can be caused by several things as well.
One thing that concerns many home builders and the buyers too is the use of vapor barriers between the walls. Some people think they are necessary to prevent moisture that can build up inside walls and other places in the home because of the outside climate conflicting with the climate inside the home. It is believed that this kind of moisture condensation can lead to mold inside the walls. Anyone who knows anything at all about mold growth will tell you that having mold living inside your walls is one of the hardest to get rid of. many times the entire walls must be torn out and replaced when it is impossible to remove the mold any other way.
Depending on whether you live in a cool climate, a hot climate, or a climate that can be both will determine what kind of vapor barrier you will need to have if any at all. While n some places a building code might demand that a vapor barrier be used, other places might not. It just depends on where you live. Vapor barriers are more often placed in exterior walls, ceilings, and roofs. The material used most often can be plastic or a foil, but there are other kinds that are used in things like metal buildings, basements, and under concrete slabs.
While the most common reason for vapor barriers is to prevent moisture from doing damage to the home, the vapor barrier is also a way to make a home more airtight. Some think this is a good idea because it helps to keep the home warmer or cooler and helps conserve on energy bills, while other believe that making a home too air tight can make the home and its occupants more susceptible to trap moisture inside when not enough air can get into the home to dry it out.
