Crawl Space Vapor Barrier
Proper insulation in a Crawl Space Vapor Barrier San Antonio is essential in avoiding certain serious structural and health issues. A crawl space vapor barrier will give one of the most effective solutions in keeping moisture buildup in your crawlspace, and it is extremely easy and inexpensive to install. A vapor barrier is made from a combination of urethane foam and rigid foam, with the former containing the pores for absorption while the latter acts as a vapor barrier, retaining heat, cooling, and humidity. It is very easy and simple to install, and can help to greatly improve the indoor air quality of a home.
Two important factors must be considered when selecting a crawl space vapor barrier. First, it must be a moisture-resistant barrier, typically composed of a six-mil thick vapor barrier. This is the minimum amount of vapor resistance that should be found on any barrier, but the higher the barrier's R-value, the greater its ability to absorb moisture and hold it. A six-mil thick barrier is typically good enough to protect against moisture buildup, although it might be exceeded if there are significant differences between the exterior and interior wall profiles of the crawl space. Two other factors to consider are the size and number of vents and the spacing between vents.
One way to find out what level of Crawl Space Vapor Barrier is appropriate for a particular installation is to measure the distance between the lowest point on the slab and the highest point on the ceiling above the crawl space. For encapsulation to occur, there must be at least six inches of free wall within a forty-five foot walkway or a twenty-five foot clear span from floor to ceiling. Any space between the walls must also be enclosed by a vapor barrier. The area between the walls can be treated as a vapor barrier, as well, if it is between the exterior wall and the interior wall. A professional contractor can help determine the correct vapor barrier to install based on the space available and the conditions of the crawl space.
Crawl space encapsulation creates an airtight seal that allows water vapor and airborne contaminants to be removed from the house or structure. Crawl space encapsulation works because it makes it much easier to dry and ventilate the house or structure. Without an airtight seal, condensation and moisture will accumulate. In time, this moisture will expand and form a humidity problem in the home. A vapor barrier creates a seal that allows air to move through the house freely, removing moisture from surfaces and floors.
If you are not certain about your foundation, you can have a professional come and do a free inspection of the foundation along with evaluating the soil around the foundation. If there is excessive foundation rotting or damage, this condition can be corrected during the free inspection. When there is excess soil or sludge in the crawl space, a standing water problem can develop, causing the accumulation of moisture within the house. You can have your foundation looked at by a professional, as well, to determine the extent of damage and if there is need for a new foundation.
Your home's existing air conditioning system, heating system, or cooling and heating systems may be contributing to the cause of excessive odors and mold spores in the home. The system, air conditioning unit, or ductwork should be inspected by a professional to determine if the systems are in need of repair or replacement. You can have your HVAC system or furnace inspected for leaks, faulty connections, or worn out parts. You may want to consider a radon mitigation system to reduce your home's chances of developing mold spores or odors.
If the source of the odor or the building's foundation seems to be the result of improper outside ventilation, a crawl space vapor barrier may be required. A professional, certified contractor or mold remediation specialist can install the barrier. In some cases, a plastic barrier may be sufficient to address the odor problem. When choosing a mold remediation expert, make sure he or she is licensed with the city or town of your choice and has many years of experience in crawl space repair and mold remediation.
If you suspect the source of your home's foul odors or if you believe you have water damage, there are two choices for you: purchase a ventilator or purchase a crawl space vapor barrier. Both products provide excellent air circulation in the home while reducing humidity levels and the number of allergens in the air. A certified professional or mold remediation expert will be able to discuss your options with you and recommend the best solution for your situation. If you choose to purchase a vapor barrier or dehumidifier, make sure you purchase one made from high-quality, durable materials that are built to withstand the rigors of crawl space conditions. With proper maintenance, the protection and performance of encapsulation systems will last for several years.
