    - Flexibility at bend dia. : 0 à 2 T.
    - Corrosion-resistance :
    Saltspray (ECCA T8) : > 600 h.
    Humidity (ECCA T9) : > 1500 h.
    - Resistance to acids : 10% HCl : excellent.
    - Durability 5000 h : no loss of sticking, decoloring, nor noticable cray-building.
    - Fire classification : M0 (according to 'annexe 21 de l'arrêté du 30 juin 1983 modifié').

Use : gives a guarantee to durability and heavy UV-exposure and is hence applied for severe atmospheric conditions (industry, coast, road tunnels).

INSULATION MATERIALS

Expanded polystyrene

Photo élément de polystyrène Photo élément de polystyrène

  • the product

    Expanded polystyrene (in short EPS) is an excellent insulation material.

    Its most important features are thermal insulation (low conductivity), low specific weight, stability and durability. In addition is this material recyclable.

    The for our panels applied polystyrene is of first choice and has been treated with fire retardant to improve the fire resistance and contains products to repulse rodents.

    Quality : EPS 15 SE : 15 kg/m³
    Quality : EPS 20 SE : 20 kg/m³


     
  • insulation capacity

    The insulation value of the expanded polystyrene varies slightly with the type and is the result of the low specific thermal conductivity coefficient, the low specific heath, and the low specific weight :

    Quality Thermal conductivity coefficient l [W/m²°C] Specific weight [kg/m³]
    EPS 15 SE 0,040 15
    EPS 20 SE 0,036 20


  • classement au feu
     
    The applied expanded polystyrene types are of self-extinguising and non-fire-propagating quality and have a fire classification :
     
    Belgian norms A1 according to NBN S 21-203
    French norms M1 according to NF P 92-507


  • durability

    The polystyrene used is stabilised and does not show any measurable aging symptoms; confirmed by many tests.

    The strenght, thermal insulation and consistency of the material remain intact with the passing of time.

    Tableau essais longue durée Knauf



  • environment

    Expanded polystyrene is an environmental-friendly product.

    1m³ Expanded polystyrene is made out of +/- 13 ltr petrol. Due to its insulating capacities and for use under normal circumstances in north-western Europe, this 1m³ will save some 6 Megajoules per month (this yields a positive balance after only a few months).

    In adition to this, is expanded polystyrene completely recylcable and recycled. All production surplusses are to 100% recycled.

    Expanded polystyrene is completely safe; non-toxic and inert. Expanded polystyrene does not contain any CFK nor HCFK. It does not contain any nutritive value and hence does not support fungal growth or other micro organisms.



THE ROCK-WOOL

Photo élément de laine de roche

  • the product

    Rock-wool is a ceramic material conceived with fibres of molten stone. Compressed blocs of these woollike fibres are, since many years, used in construction industry as an insulating material

    Its main features are its thermal insulation (low thermal conductivity), its non-combustibility and fire-resistance. In specific situations it is appreciated for its acoustic performances.

    The for our sandwich panels applied rock-wool is of first choice and of the quality with oriented fibres and high density, in order to achieve optimal mechanical performances, more in particular its incompressibility.

    Quality : 100 kg/m³ oriented fibres


    - thermal insulation capacity

    Thermal conductivity coefficient l = 0,40 [W/m²°C]
     

  • fire reaction

    Classement au feu

    Rock-wool is completely fire-safe, and resists without any problems to temperatures up to 1000 °C. Also under fire load, its structure and insulating qualities remain intact

    Rock-wool is incombustible
     

    • Dutch norms incombustible according to NEN 6064
    • French norms class M0 according to CECMI, April 1999

  • acoustic insulation

    There are two features of the material that yield advantages on acoustic level : its specific weight and its air-open structure.

    In order to achieve acoustic insulation in between two rooms, one has to install a partition of high weight. Rock-wool has a high specific density and hence is very suitable.

    In order to achieve acoustic absorption for a noisy room, one has to conceive walls with an air-open peel. The coarse and open structure of the rock-wool, fitted under a perforated sheet is perfectly adapted to this.

  • - durability

    The used rock-wool is stabilised and does not show any perceivable aging phenomenons.

    Strenght, thermal insulation and consistency of the material remain intact also with passing time, as is show in experiences over many years and is confirmed by several applications.

    Tableau essais longue durée Rockwool

  • environment

    Rock-wool is an environmental-friendly material.

    1 Kg of Rock-wool is conceived with an energy input of 10 to 20 Megajoules. Due to its insulating capacity and used under for noth-western Europe normal circumstances, this kg will save some 5 to 10 Megajoules per month, depending on its application (thus a return on energy of 1 to 4 months).

    In addition is rock-wool not a burden to the environment, as it is a natural and inert product and is rock-wool completely recyclable.
