Application Area

  • Wall surface to be insulated is cleaned and prepared for the application.
  • Boards are cut according to the wall size so that there is 1 cm.
  • gap off the floor and 0.5 cm off the ceiling is left.
  • Special gypsum fixing mortar is put on the glass wool side of the board, so that 3-5 kg (8-9 chunks) per square meter is applied.
  • Kalibel boards are placed on to the wedges of 10 mm which were put in beforehand.
  • After the boards are leaned against the wall, a rubber hammer and a floating rule are used for levelling.
  • The boards are supported until the adhesive sets.
  • The joints are filled with a special net and paste.
  • The application is completed with top coat paint.
  • Since the walls with Kalibel application work with mass-spring-mass principle, they offer better sound insulation and do not impose load on the building than the one layered and heavy walls which only work with mass principle.
  • Aluminium foil between glass wool board and gypsum board prevents the risk of condensation.
