Energy-efficient buildings and high-quality residential spaces could not be imagined without expanded polystyrene [EPS]. In developed countries, 90% of all facades are insulated with expanded polystyrene. It is essential in most construction assemblies due to its exceptional properties.
It is used wherever we need thermal and sound insulation of walls, roofs, floors, and other construction assemblies for all types of buildings. The investment in EPS thermal insulation pays off very quickly from an energy standpoint because every kilogram of EPS correctly used saves 400 liters of heating oil over 50 years.
Water and moisture do not bother EPS due to its cells being fused together with steam, and no harmful adhesives are required. The name “Styrofoam” has become a synonym for insulation panels made from expanded polystyrene, with the abbreviation EPS. EPS material’s properties are such that the granules increase in volume up to 60 times at high temperatures. EPS is environmentally friendly and is the only thermal insulation material that can be 100% recycled. It is much better than wood in terms of water vapor permeability.
Expanded polystyrene is recognized in most EU countries as a material used in construction that is self-extinguishing - insulation that in a fire melts, but does not spread the fire further. Facade systems with expanded polystyrene insulation, covered with reinforced plaster and finishing layer, fall into the excellent E class reaction to fire. All EPS construction panels are classified as E class reaction to fire according to EN 13501-1 standard, or class B1 according to DIN 4102 ("self-extinguishing material").
From what is stated, it is obvious that there are many countries in the EU where 90% of all facades are insulated with facade polystyrene. EPS facade insulation has often, without exaggeration, been used in a large number of buildings of various purposes up to a height of 22 meters; residential blocks, health centers, schools, kindergartens and even gas stations!
Styrofoam in facades and floors has many advantages over other insulation materials that are water-sensitive (roof leaks, floods, water firefighting, etc.). When fully submerged for a month, Styrofoam sheets absorb less than 5% volume. After drying, they continue to perform their insulating function. The allowed water absorption of EPS boards (maximum 40%) in the heating season on facades is even 4 times greater than that of fibrous insulation, which can cause permanent damage due to condensation. With sensitive materials in contact with water and excessive moisture, expensive replacement of damaged surfaces may be necessary.
We cannot imagine energy-efficient buildings and high-quality residential spaces without expanded polystyrene [EPS]. In developed countries, 90% of all facades are insulated with expanded polystyrene. It is irreplaceable in most construction assemblies due to its exceptional properties. It is used wherever we need thermal and sound insulation for walls, roofs, floors, and other construction assemblies for various types of buildings.
