The special joint geometry is one of the most important characteristics of the insulating panels. They have been developed to meet high demands in terms of their joint tightness which is needed to meet the demands of refrigerated store and deep freezer storage construction. The following alternatives are available to choose from, to meet your requirements and budget.

Labyrinth Joint

Superior joint design

Geared toward the special requirements we have invested years of research to develop our joint design. Through to the optimized accuracy in fit, the system offers an outstanding air-tightness and reduce the thermal bridging.

  • Optimized joint design and accuracy in fit
  • Improved joint stability
  • More excellent air-thightness and no loss
    of coldness

With thicknesses of between 60 and 220 mm, our panels seal safely without the need for additional measures.


In addition, we offer our cold storage panels in 40mm thickness with our standard joint.

Horizontal Joint

Horizontally installed ems-isolier® cold store panels for cold and deep-freeze stores are visually pleasing and of high-value design. We have re-designed the joint geometry for horizontal installation, as an asymmetrical panel joint offers a range of benefits.

On the outside, the inclination of the groove flank prevents water from penetrating. Even in the case of driving rain, the water can run off in a controlled manner without getting into the joint. This prevents the joints from freezing. The opposite side of the joint has a groove for accommodating the well-proven ems-isolier® hollow chamber profile. Thus, a visually homogenous wall surface is created inside the cold or deep-freeze store and hygienic conditions are ensured.

By using ems-Elast in the outer joint, additional protection against driving rain is achieved.
