UNDERFLOOR INSULATION

Foilboard panels provide a practical rigid insulation solution for underfloor applications, helping improve comfort and reduce heat transfer through the floor. Lightweight and easy to handle, Foilboard can be installed under or between joists in timber and steel-framed floors using Floor Saddles, Flexifit or Retrofit methods.
