IsoBoard, high-density extruded polystyrene rigid thermal insulation board, has a 100% closed cell structure!
Attributes: The use of advanced, state of the art manufacturing technology makes it possible to guarantee exceptional attributes, such as:
- High resistance to water vapour diffusion and water absorption
- Long term low thermal conductivity/High thermal resistance
- Uniform density
- High compressive strength
- Ageing resistance as well as resistance to bacteria and micro organism growth.
These and many other features make IsoBoard an innovative and cost effective thermal insulation product. This versatility means that IsoBoard is used in various applications in numerous different markets. IsoBoard contains gases which have been accepted in terms of the Montreal Protocol with minimal ozone depletion potential.
Heat Flow: IsoBoard provides excellent resistance to heat flow. IsoBoard reduces heat flow into buildings in summer and reduces internal heat outflow during winter. The heat flow resistance will reduce over time when exposed to air and will also be influenced by water content. Accordingly, a design heat flow value of 0.03 W/m°C is appropriate. (Confirmed by SAFIERA RGHB)
Water: IsoBoard will only absorb 1 % maximum water by volume. Heat flow resistance will reduce by a maximum of 3%.
Water Vapour: IsoBoard’s closed cellular structure provides exceptional resistance to water vapour permeability. Heat flow resistance due to vapour penetration (including water absorption) can reduce by a maximum of 8%.
Fire: IsoBoard contains self-extinguishing fire retardants, non-flammable blowing gasses and will not propagate fire in exposed roof applications.
Sound Insulation: IsoBoard is a thermal insulator and should not be used in isolation to achieve noise reduction. Consult a specialist with respect to noise reduction systems.
Operating Range: -30 to +60°C.
Density: IsoBoard has a high density of 32-36 Kg/m3. The compressive strength ranges from 160 to 310 kPa, dependant on the thickness of the board. The thicker the board, the higher the compressive strength.
Chemically Inert: IsoBoard is odourless, chemically inert and does not supply nutrition for pests, or support micro organism growth.
