Types Of Isoboard Applications

  • Isoboard Ceilings: Standard Ceilings as well as Exposed beams. In all new homes, as well as a retrofit in existing homes.
  • Wall Cavity Insulation Isoboard: Ideal for all new builds to reduce Thermal Heat transfer through the brick walls.
  • Under Floor Insulation: This is great to reduce the cold air from below. Especially in homes built near rivers or dams.

Isoboard Thermal Ceiling insulation is undoubtedly one of the best ceiling options on the market today. Significantly Isoboard Ceilings have excellent thermal insulation properties as well as an aesthetically pleasing good look. Unfortunately, the only downfall is that these ceilings do not reduce noise via the roof into the home.

For this reason, it would be essential to fit insulation with a high NRC (Noise Reduction Coefficient). For example, the New Think Pink Aerolite with TEL Fiberizing Technolgy or the Knauf Ecose Insulation will stop noise from metal roofs. Unfortunately, the Isotherm Insulation has a very low NRC. On the other hand, the new Pink Aerolite is installed in nightclubs and pubs as insulation and soundproofing. These thermal insulation ceilings reduce the amount of roof insulation required.
