Isoboard Ceilings

The Isoboard Ceilings are the new fashion in homes in South Africa. These ceilings are available in thicknesses from 25- 80mm thick — ideal for all homes as well as homes with limited ceiling volume space to achieve the correct R-value. Having Isoboard Ceilings installed is a neat and clean operation. Most homes can have ceilings installed in two to three days for an average house. The application is almost dust free as there is no skimming and dust in these applications.

Advantages of Isoboard Ceilings

  • Homes are cooler in summer and warmer in winter.
  • Isoboard in conjunction with added roof insulation is far more energy efficient as the Isoboard already has an R-value.
  • Great looking clean, neat finish.
  • Finally, Isoboard Ceilings are not affected by water leaks.
  • Installing Isoboard as a ceiling is quick and neat with very little dust in the home when compared with traditional ceilings.

Disadvantages of Isoboard Ceilings

  • Unfortunately, Isoboard has little to no NRC (Noise Reduction Coefficient). As a result, Isoboard allows the sound of rain noise on the roof to travel into the home like there is no ceiling. On metal or sheeting roofs this will sound like a gunfight taking place on the roof in the case of heavy rain.
  • Installing 135mm Aerolite above the Isoboard will stop the noise problem in its tracks. The result will be well-insulated ceiling with excellent acoustics as a result of the 135mm Aerolite and Isoboard ceiling combination.
