Intensive core insulation

Windows in a class of their own

IKD®: GEALAN's pioneering role

GEALAN is a pioneer in factory foam filling of profiles and launched the first foam-filled   window and accessory profiles back in 2010.

Knowledge born of experience

Today GEALAN has a wealth of expertise in how to incorporate this technology into profile production.

Further benefits

  • The profiles are foam-filled in the factory for GEALAN customers.

  • No additional investment is required on the part of the fabricator.

  • No changes required to the customer's production process.

  • IKD® profiles can be recycled.

Systematic use

GEALAN uses IKD® foam technology in a targeted manner in various systems, products and new developments to increase the heat insulation.


For the first time, GEALAN's IKD® intensive core insulation offers window manufacturers an efficient and economic way of producing windows that satisfy the highest demands in terms of heat insulation.

IKD® intensive core insulation does not require any investment in new machines. The foam is injected into the profile chamber in the extrusion plant.

The window manufacturer then receives the finished foam-filled profile off the shelf. Watch our film about window production with IKD®.
