downloadIsoBoard is a rigid,  high density, extruded polystyrene, manufactured in different thicknesses and lengths to meet almost any building thermal insulation requirement in the temperature range -30 to +60 °C.

IsoBoard has board of Agrèment SA certificate for five popular applications, which certify IsBoard is fit for use as recommended. IsoBoard is without doubt the most versatile thermal insulator available.

Thermal insulation provides a barrier to heat transfer, which keeps heat energy on one of the board or the other. Insulation does not, of itself, provide heating or cooling, but rather controls where heat energy should be, either inside or outside.

Advantages if IsoBoard

cropped-IMGP4328-Copy7.jpgThe advantages of IsoBoard are in its effectiveness as a thermal insulator, ease of installation, high compressive strength, resistance to moisture and excellent performance in fire situations. The board is extremely durable and will last for the life of the building, with minimal drop off in thermal performance.

IsoBoard can be painted with water based paints when used in exposed applications, and washed to clean if necessary.

Thermal Conductivity of IsoBoard

The thermal conductivity (k Value) of 5 year aged IsoBoard at 90% relative humidity is 0.03 W/m °C. This K value for both aged and wet IsoBoard is termed the “design value” used when performing heart flow calculations for building elements employing IsoBoard Insulation. NB the “design value” is the worst case expected conductivity of IsoBoard at the end of the building’s useful life, you can rely on this value! The thermal resistance ( R Value) if IsoBoard is calculated by dividing the thickness of the IsoBoard by the design k-Value, to achieve the following table:Untitled

 

 

 

 

 

Fire Performance:

fireTestIsoBoard is Classified as B/B1/2/H&V in terms if SANS 428. This means that although the board is combustible, it poses no flame spread hazard and can be used in any building type in a horizontal or vertical application, both with and without sprinklers, with the exception of regulated buildings requiring non-combustible materials, such as hotels and hospitals. 

Exposed to fire, IsoBoard shrinks away from the heat source. There are no flaming droplets, and no flame spread. The gases released as a product of combustion are less toxic than burning wood.

Installation Alternatives: 

Resisting thermal heat flow inwards through the roof is the primary purpose of insulation. IsoBoard can be installed in a variety of applications to effectively meet this objective:

  • Over Purlin for retail, commercial, industrial and residential is steel frame roof applications.
  • Inverted Roof for concrete roofing systems where insulation is installed over waterproofing.
  • Under Soffit installed below a concrete deck where an inverted roof its inappropriate.
  • Nail up Ceilings replacing existing ceiling systems with an insulated ceiling.
  • Over rafter  for residential and low cost housing appliactions.
  • Over Truss for retail, commercial and residential exposed wooden truss applications.

IsoBoard is employed in other building applications with the objectives of energy cost savings and comfort: 

  • Within Cavity Wall to maintain a constant internal building temperature.
  • Under surface bed to insulate floors ( with or without hating/ cooling systems) from the effect of the surrounding earth temperature.
  • Under soffit above exposed parking areas to insulate retail and residential environments from : cold foot syndrome”.
