How to install Enertherm Insulation

Boards should be stored in a dry space with a flat surface where the board is protected from all weather conditions such as rain or sunlight. If a board does get wet allow and is not damaged allow the board to dry completely before installing.

Always work on the insulation boards on a base that is dry and free of dirt.

During processing, you need to take measures to prevent damp from penetrating inside the insulation boards.

IKO Enertherm insulation boards can be fitted using several methods:

  • On a profiled steel roof, fit continuous joints at right angles to the groove direction.
  • With a so-called wild bond, it is highly recommended to saw a section at the end of the first row to fit to size. The cut piece is used as the first piece layer at the start of the second row. Always make sure that the joints are staggered at least 20 cm.
  • With a so-called stretcher bond, you should always use a half board at the start of the next row and fit the insulation boards together with sealed joints. Once all boards are fitted IKO PU FIX GUN is advised to seal any openings between the insulation boards at channels and connections with walls. This is necessary to prevent the formation of a thermal bridge. The surplus foam can be cut away and all joints taped with ALU TAPE.

Before you begin:

  • The base must be flat enough to provide for adhesion and have no cracks bigger than 5 mm/m1.
  • The base must be completely dry before glue is applied; gluing in any degree of water is not permitted.
  • Ensure the base is clean by removing any dirt, dust, and loose items from the base, as well as any oil residue and cement.
  • In the case of bases containing oil or greasy bases or existing roof coverings, the possibility of gluing needs to be investigated for each individual situation by doing a glue test.

Step 1:

Apply the insulation boards to the base in stretcher bond, partially glued.
On a steel roof with IKO pro-PU adhesive, about 200 g/m² (glue marks left and/or right of the dimple, exclusively in accordance with the manufacturer’s guidelines).

Step 2:

Then, no more than 15 minutes after applying the PU adhesive (no longer than 5 minutes in temperatures above 30 °C), apply the boards and press them together by running over the surface at least once.
For gluing a partially glued roof covering system onto the insulation boards, apply at least four strokes of adhesive crosswise along the length of the insulation boards (adhesion percentage at least 40%). For gluing a fully glued system onto the insulation boards with warm bitumen (IKO Enertherm MG/BM), glue at least 50% of the surface.

Step 3:

Consumption depends on the application and the manufacturer’s specifications. Mechanical fastening Fit the IKO Enertherm insulation boards onto the base in stretcher bond; fasten the boards or board sections additionally as follows:

  • Board size 1,200mm x 2,400mm – at least 6 fasteners
  • Board size 1,200mm x 1,200mm – at least 4 fasteners
  • Board size 1,000mm x 1,200mm – at least 4 fasteners
  • Board size 600mm x 1,200mm – at least 4 fasteners

For fastening a wooden or steel roof IKOFIX COMBI-S or IKOFIX EDS-S. For fastening a concrete roof IKOFIX TLK in combination with IKOFIX EDS-S.
