Keeping your home dry is essential for its well-being. Unfortunately, it is also one of the most difficult tasks for a homeowner. Water can get in anywhere, so keeping it out is a home-wide effort. One important element in your fight against water intrusion is a vapor barrier. Vapor barriers come in different forms. Some are in the form of paint that can simply be used as a primer. Others are made of paper, but the most common ones are made from polyethylene plastic. Regardless of the type of vapor barrier you use, it will need to provide full coverage. A rip in your sheet and a patch that you miss painting will have the same effect, it will keep the vapor barrier from working properly.
This is why it is important to be careful when installing these sheets since they could snag on something and rip. If you are installing them in an area that has a lot of sharp edges and roughness, you can use a thicker material as a vapor barrier.
