Thermal insulation

When sealing windows and exterior doors, thermal insulation is a physical property of the , the consideration of which is also required by the legislator through rules and regulations introduced under law. In this context, the Energy Saving Ordinance (EnEV) and DIN 4108 "Thermal Insulation and Energy Saving in Buildings" are of particular importance.

Heat insulation in new buildings #In newly constructed buildings, a type of construction that is as free of thermal bridges as possible should be chosen.

This is essentially made up of three requirements in the window connection:

- Insulation elements should be joined without gaps

- The sealing materials should have the highest possible thermal resistance.

- The construction should be chosen in such a way that the maximum possible amount of sealing or insulating elements can be accommodated.

Heat insulation in old buildings

In general, the same standards apply to renovation as to new construction. In practice, however, these can only very rarely be realised, as one is dependent on the existing framework conditions.

That is why it is very common to work with cover strips that are equipped with sealing tapes. Such solutions are certainly not optimal in terms of thermal insulation, but in many cases they are the only solution.
