Vapor Barrier Crawl Space
Do not insulation crawl space walls if the crawl space is wet or ventilated with outdoor air. Poly vapor barrier crawl space ground is covered with a poly shield as a barrier to rising moisture to the house.
Energy efficient products
Energy efficient products use less energy to operate, thus saving you money by reducing your heating, cooling and lighting costs. Energy efficient choices can save families about a third on their energy bill with similar savings of greenhouse gas emissions, without sacrificing features, style or comfort. The ENERGY STAR LOGO helps you make the energy efficient choice. The Department of Energy says, the best approach to insulating an unventilated crawl space is to seal and insulate the foundation walls rather than the sub floor. Remember, your crawl space is probably the least used part of your house, but it is equally capable of being a culprit of higher energy costs. It is useful to increase energy efficiency and home comfort and lower bills.
Crawl Space
Sealing your crawl space is the first step. If insulating the crawl space is a concern, we recommend insulating the foundation walls with polystyrene insulation. If radon is present, a radon mitigation system will require ventilation of the crawl space to the exterior (even in a vented crawl space, elevated levels of radon can be present). Provide your house with crawl space insulation by lining your crawl space with Styrofoam board to insulate the walls and eliminate ground moisture from transferring to your living space. Crawl spaces are open spaces beneath a portion of a home.
Crawl space is very common in the homes that have high moisture content in the soil. Crawl space insulation will reduce the amount of heat your home loses through the floor. Crawl space insulation can be installed directly beneath your home’s floors, or at the perimeter of the crawl space on the inside of the foundation walls. Crawl space ventilation became essential to avoid moisture damage in modern, energy efficient homes. Crawl space vents may now be eliminated with newer high performance vapor barriers. Part of keeping your crawl space dry involves a sump pump.
Finishing Basements
Finishing a basement, especially if it is built in moist ground, is risky. Make sure you stop your water problem before you spend thousands of dollars on finishing your basement. The most common way to insulate a basement is by building a framed wall, filling it with fiberglass batts, and covering it with drywall. This unfortunately creates a cavity that is difficult to air seal and difficult to dry if the basement wall ever gets wet. In any case, remove any causes of foundation moisture problems for example, by installing gutters or sloping the ground away from the home before finishing the basement. When a residence is insulated it is important to make sure areas such as the basement, crawlspaces, attics, and the garage are insulated. Rigid foam boards are made to be used in confined spaces such as exterior walls, basements, and foundation walls. A vapor crawl space barrier is essential to stop water vapor from the soil from penetrating through your basement and crawl floors and walls.
Foam board and Spray
Foam board insulation is placed between the exterior finish and the studs of exterior walls. Also, spray foam insulation and is a high performance Soy Based product. Spray foam insulation can result in less conductive, convective and radiant heat transfer, lower infiltration rates, and lessen duct losses. For a more structurally sound building, can result in significantly smaller heating and cooling systems and better comfort levels for the occupants. In order to improve on your existing crawl space entry door, you can install foam board insulation on the backside of the door via adhesive or small screws.
Mold In Crawl Space
Mold can be found in the ductwork of cooling and heating systems. Mold growth can be almost any color, white, black, green, fluorescent. During the summer, warm humid air can flow around the crawl space insulation batts in and create condensation, and can create mold and decay problems in the floor system.
