What is polystyrene insulation?

polystyrene insulation is a type of solid insulation of foam, which is commonly used in residential and commercial environments. It has an exceptional ability to insulate against noise and extreme temperatures. It is also waterproof and long -term. These properties are connected to make polystyrene insulation an exceptionally useful product.

For insulation, two types of polystyrene are used: enhanced and extruded polystyrene. The widespread polystyrene, also called bead plate, has a lower density that the extruded species, and is cheaper, but also has slightly less insulating force. This is due to its gross cells and the fact that they contain only air. Extruded polystyrene insulation has finer cells or balls and contains a mixture of air and refrigerant, making it a better insulator. It starts in the form of solid polystyrene crystals, which are combinations with special ingredients and molten. In the extruder, the temperature and pressure are firmly inspected to convert the crystals into a thick plastic liquid. This liquid is then forced toforms or died. When it emerges from the matrix, it cools and expands to foam, which can be cut or shaped on any specifications.

This process gives extruded polystyrene insulation a smooth, uniform surface that cannot be duplicated in other types of insulation. Its properties are also suitable for creating panels or stackable blocks for the purpose of insulation of walls in households. Foam can be easily cut for electrical connection to pass or near it. These mutual foam formations are often made of hollow areas that can be filled with concrete that creates a grid of columns and beams when it is dry.

Polystyrene insulation materials are often relatively expensive and co -covers approximately five to ten percent on the cost of building a house. However, heating and cooling savings can allow the homeowner to recover additional costs throughout the life of the structure. ConcreteThe insulation grid offers its own advantages in addition to polystyrene. These include be impermeable for many pests, such as thermites that can cause structural damage to the ordinary wooden frame of houses if they remain unchecked.

As with any alternative building material, polystyrene insulation has certain disadvantages. In addition to increased costs, it is also flammable and requires a coating for protective fire fire. It can also be slightly degraded if it is exposed to sunlight or temperatures above 165 degrees Fahrenheit (74 degrees C). Since most domestic insulation is never exposed to this type of temperature, it is a small practical risk.
