Styrodur or Styrofoam - Comparison

Styrofoam is a good material for insulation.

Material properties of Styrodur

  • Styrodur is a finely porous building material, which is extruded from Polystrolhartschaum and is pressed into plates.
  • The surface is hard, pressure-resistant and smooth. The color is usually green or blue.
  • The sealing properties are also better than with polystyrene. The biggest advantage of the building material is that it absorbs very little water because it is pored.
  • This makes it ideal for insulating basement walls or flat roofs.
  • The substance is tested according to DIN 4102 and is classified as flame resistant building material.
  • The density and the weight of styrodur 52 kilograms per cubic meter.
  • The price and the energy required for the production are relatively high.

Material properties of polystyrene

  • Styrofoam is a coarsely porous building material, which has a rough surface. He is expanded from Polystrolhartschaum.
  • The pressure load is relatively low. Next take styrofoam to moisture, thereby losing insulating capacity.
  • Styrofoam plates usually have the color white and a density of 20 kilograms per cubic meter.
  • Styrofoam is also tested according to DIN 4102 and is also a flame retardant construction material.
  • The price and the energy required for the production can be classified more as low in Styrofoam.

Processing of materials

The processing of styrofoam and similar Syrodur basically. The substances react any differently to solvents that can be contained in adhesives and coatings. Here you should first take a test.

  • Cut to the materials with knife, saw or thermal cutters.
  • For bonding you should use special Styrofoam glue.
  • You can coat the surfaces with casting resins, Akryllacken or putties and then grind smooth surfaces. Especially in model or for decorative purposes, this technique is well suited.
  • On colors suitable solvent-free paints, such as acrylic, tinting or poster paints.
