Simprolit Building Physics

    SIMPROLIT BLOCKS HAVE UNIFIED MARKING SYSTEM:

    1. Filling of hollow longitudinal gaps, oriented towards the inside of the structure:
      О - without filling;
      B - concrete;
      S - Simprolit polystyrene concrete.
    2. Transversal thermo-insulation pads, in the middle of the blocks and sideways:
      О - without transversal thermo-insulation pads;
      P - longitudinal thermo-insulation pad made of polystyrene (styrofoam), its thickness depending on the type of the block;
      S - longitudinal thermo-insulation pad made of Simprolit one-layer (SOP) plate, its thickness depending on the type of the block.
    3. Longitudinal thermo-insulation pads, oriented towards the outside of the wall, their thickness (in cm) depending on thermic calculations.
      О - without transversal thermo-insulation pads;
      P (1, 2……) – longitudinal thermo-insulation pad made of polystyrene (styrofoam), thickness (1, 2..) cm;
      S (1, 2……) – longitudinal thermo-insulation pad made of Simprolit one-layer (SOP) plate, thickness (1, 2………) cm.

    Example 1: SB25 (B-0-P1) symbolizing 25 cm thick Simprolit block (filled with concrete - without transversal thermo- insulation pads - with 1 cm thick longitudinal thermo-insulation pads made of polystyrene)

    Example 2: SBS20 (B-S-P2) symbolizing 20 cm thick type "S" Simprolit block (filled with concrete - with transversal thermo insulation pads made of Simprolit one-layer (SOP) plate - with additional 2 cm thick longitudinal thermo-insulation pads made of polystyrene) .

    SYMBOLS USED FOR THERMO-SOUND-PHYSICAL PROPERTIES OF SIMPROLIT BLOCKS:

  • R0 [=] m2 °C/W - Total heat transfer resistance coefficient for facade wall structure
  • R [=] m2 °C/W - Heat transfer resistance coefficient for facade wall elements
  • R0тр [=] m2 °C/W - Required total heat transfer resistance coefficient for facade walls
  • R0 = R + 1/αв + 1/αн R0тр
  • where is

  • αв [=] W/m2 °C - Heat transition coefficient on the inside surface of the facade wall
  • αн [=] W/m2 °C - Heat transition coefficient on the outside surface of the facade wall
  • K [=] W/m2 °C - Heat transfer coefficient for particular elements of the wall
  • ΣK [=] W/m2 °C - Total heat transfer coefficient for walls made of different elements
  • K [=]: Summer stability (min. 10 - for walls facing north, 15 - for other walls, 25 - for roofs)
  • D24 [=] W/(m2 °C) - Heat inertia coefficient
  • t1 [=] °C (ti inside temperature, te outside temperature) Comfortability
  • where is

  • ti= Calculated temperature of the inside air (according to the building design standards and technical norms)
  • te = Calculated temperature of the outside air (according to the building design standards and technical norms)
  • Rw [=] dB: Sound insulation level of the facade wall
  • q [=] kg/m2 - Weight of the wall per m2 (together with filling, insulation pads and double-sided plaster layer)

Remark:

in the following review the coefficients related to certain block types are given:

without filling, with smallest and highest heat transfer resistance.
