So, you’ve excavated the crawl space under your Austin home and are now wondering how to insulate it. It is not difficult to install spray foam insulation in excavated crawlspaces, but it is important to choose the right insulation and ensure the installation is done correctly. A crawl space can often be a problem area for a homeowner. In Austin Texas the area is usually damp and can experience issues with excess moisture. When this moisture begins to impact the home’s structure, it becomes a major problem. Most homes with a crawl space also have a wood base that sets on top of the crawl space. Moisture from the crawl space can create mold and mildew on this wood structure. Termites can also become a problem if the crawl space is not properly insulated.
When a home is built with a crawl space, the area must be insulated properly to prevent outside air from coming through the floorboards. Quite often, a contract will install a standard insulation vapor barrier which is not enough to keep mold and moisture from soaking through the vapor barrier and affecting the structure of the home.
The standard vapor barrier is only four or six millimeters of plastic. This type of vapor barrier is usually not fire retardant and is very thin. It does very little to prevent air from entering the crawl space through pipes, vents, or the crawl space door. These types of vapor barriers are typically attached to the home either by staples or seal tape. These both create holes in the liner, allowing more air and moisture through.
The right vapor barrier liner must cover all areas of the crawl space to provide proper insulation. This means the contractor should install a 20 millimeter, waterproof, fire-retardant, anti-microbial and puncture resistant vapor barrier. This type of insulating barrier will prevent odors, mold, and even pests from the crawl space.
In addition to the right vapor barrier, it is also a good idea to install insulation in excavated crawlspaces. Many people forget about adding insulation to the crawl space, but this can really help reduce energy costs. Properly insulation a crawl space can also provide other benefits.
Properly insulation a crawl space helps protect pipes from freezing in cold weather. It also helps keep your home warmer in the winter and cooler in the summer by helping your home climate control system to maintain a constant temperature. This helps reduce energy bills. Insulation in the crawl space can also help prevent mold and mildew problems.
There are several types of crawl space insulation. The most common type used in fiberglass batts and fiberglass rolls. Foam board is also used by some contractors and builders. The least expensive option is usually fiberglass batts.
When choosing insulation for your crawl space, it is important to know if your crawl space is vented. Many older homes have vented crawl spaces. These are not very energy efficient and can actually exacerbate moisture problems. There are ways to insulate a crawl space that can help eliminate the problems that are often associated with vented crawl spaces.
There are a few steps to installing crawl space insulation. The entire area in the crawl space must be sealed. Proper equipment should be used. Anyone working in the crawl space should wear goggles, long sleeves and long pants, and gloves. It is recommended to hire a professional to install crawl space insulation since it requires certain skills to do it properly.
It is important to properly insulate your crawl space to prevent moisture problems and to reduce energy costs. It is a good idea to hire someone to install insulation in excavated crawlspaces to ensure the job is done correctly.
