Liquid foam insulation materials can be sprayed, foamed-in-place, injected, or poured. The most common thermal insulation materials are polystyrene foam, mineral wool and polyurethane foam, which are used in buildings both as thermal insulation and as effective acoustic insulation. These panels, although more expensive, are more fire and water vapor-diffusion resistant than EPS. Liquid insulators are used in transformers, regulators and oil circuit breakers where they help to dissipate the heat generated by convection. Ask contractors about their air-sealing services and costs as well, because its a good idea to seal air leaks before installing insulation. This natural material is one of the favorite insulators to many. Types of Insulators Used in Transmission Line. With closed-cell foam, the high-density cells are closed and filled with a gas that helps the foam expand to fill the spaces around it.
