Hybrid insulation means that different kinds of insulating materials are going to be combined. Reasons for this can be:

  • To save space and compactness
  • To save wood
  • To combine with another material already present
  • To combine with insulating roof plates
  • To upgrade older buildings


Within the DuoFoil range, we have both vapour-permeable and vapour-tight certified multifoils that allow for responsible hybrid insulation. We can calculate the Rc value for your situation, and prove that we meet the building act requirements.

  • Mineral wool e.g. from Isover, Rockwool or Knauf,
  • Rigid foam boards from e.g. Kingspan or Unilin
  • Wood fibre insulation from e.g. Gutex or Steico
  • Flax insulation from e.g. Isovlas
  • Cellulose insulation from e.g. Climacell
