All You Want To Know About Polystyrene Insulation

2013-10-09

When it comes to home insulation, the most talked about insulation is polystyrene insulation which is a type of a rigid foam insulation, commonly used in residential and commercial properties. Not only it has the capability to insulate against noise and extreme temperatures but it is also waterproof and long-lasting. Combination of these well worth qualities make polystyrene insulation an exceptionally useful product.


There are two types of polystyrene that's used for insulation: expanded and extruded polystyrene. Expanded polystyrene, also called bead board, has a lower density that the extruded kind, and is less expensive, but also has slightly less insulating power. This is because of its coarse cells and the fact that they contain only air. Extruded polystyrene insulation has finer cells or beads, and contains a mixture of air and refrigerant gas, making it a better insulator.


Extruded polystyrene, due to the way in which it is made, has other qualities that make it a superior choice for insulation. It begins in the form of solid polystyrene crystals, which are combined with special additives and melted. In an extruder, the temperature and pressure are tightly controlled to convert the crystals into a thick plastic fluid. This liquid is then forced into a mold. Upon emerging from the mold, it cools and expands into foam, which can be cut or shaped to any specifications.


This process gives extruded polystyrene insulation a smooth, uniform surface which is impossible to duplicate in other types of insulation. Its qualities also make it well-suited for formation into panels or stackable blocks for the purpose of wall insulation in homes. The foam can easily be cut for electrical wiring to be run through or near it. These interlocking foam formations are often made with hollow regions that can be filled with concrete which creates a grid of columns and beams when dry.
