Tomball Vapor Barrier Installation Services

We can use a polyethylene plastic vapor barriers between insulation and interior wall board in areas of cold climate. We ensure that all air gaps into any wall and ceiling cavities are blocked. The exterior face of the wall or floor cavity remains permeable so as to allow dissipation of any moisture that might enter the wall cavity.

An exterior vapor barrier can be installed in a hot and humid climate to keep the outside humidity from penetrating into the walls. We can also recommend a vapor barrier against the concrete surface since below-grade walls and floor slabs transmit ground moisture through concrete walls or slabs. For crawl spaces a polyethylene moisture barrier is recommended. We can place them directly over the exposed earth.

How we install the vapor barrier.

First we have to ensure that your buildings meets standards for proper ventilation before sealing them with complete vapor barriers. Modern homes that are tightly sealed for energy efficiency should also have air-to-air heat exchangers or other methods of ensuring a good exchange of fresh air

We will install vapor barriers on the side of the wall that experiences the hotter temperature and moister conditions. For other spaces, we will recommend oil-based paints or vapor-barrier latex paints as an effective moisture barrier.

We will also seal all wall cracks and holes in the walls being vapor-proofed. This will block air gaps. We have equipment needed such as a special sealing tape to join sheets of the polyethylene sheets being used. Our team ensures complete air blockage to provide a suitable moisture barrier and maximize your wall’s energy efficiency.

For spaces around electrical boxes at outlets, switches, or ceiling light fixtures, we use acoustic spray-foam sealant or sealant tape.
