There may not be one “best” insulator as it may vary depending on the area and contractor. However there are a number of commonly used insulation methods that will proved great insulation to a crawl space. These insulations are fiberglass, mineral wool, cellulose, polyurethane foam, and polystyrene. Fiberglass is very popular because it is cheap. It will provide great insulation from the heat and is non-flammable adding another great feature. However, the process of handling it can be quite tricky. Fiberglass is made with thin strands of glass and therefore can cause cuts. The dust that comes of fiber glass can also be very harmful as it can enter the lungs and eyes. Fiberglass should be installed by experienced personnel who have the tools to safely install it.
Mineral wool may provide a great solution for insulation. It is sometimes composed of different materials. However, there are no additives in mineral wool to make it fireproof, so it may be bad in areas of extreme heat. Cellulose is a very eco-friendly insulation option. It is made from recycled cardboard and paper, and actually may be great in preventing fires. This is because it is built to be compact. So compact in fact, that there is no oxygen to fuel any flames. Therefore minimizing the impact of a fire. However, cellulose may not be good for those with heavy allergies. And it is difficult to install. So finding skilled contractors who know how to use it may be difficult. Polyurethane foam is one of the more expensive types of insulation, but it is light and can be sprayed on to any area to insulate it. Like other insulations, it is fireproof. This foam will need to be installed by professionals who are licensed and have experience as it is a spray and may contain toxins that can cause those without proper training to become light headed. Polystyrene is a water proof thermoplastic foam that is exceptional for sound and temperature insulation. There are different variants of this foam that may provide more insulation at a higher cost to you. This foam is generally bought in blocks and may be great for insulating walls. Although it is very useful, it is flammable and will need to be covered with a fireproof coating to ensure that it does not contribute to a fire if one should occur. Furthermore, the safety may be an issue as it is known to have caused certain health problems and environmental issues.
