Loggia: the construction

Depending on the structural characteristics of a loggia, the floor must be constructed differently. What options are here, and what must always be respected, you will learn in detail in this post.

Types of loggias

A loggia can be built in different ways. Depending on the construction, the floor structures then differ fundamentally from each other.

  • classic loggia in the true sense
  • Balcony on building top or on an extension (flat roof terrace or roof terrace)
  • ground floor loggia
  • classic balcony (often referred to as "loggia")
  • classic ground-level terrace (sometimes called regional loggia)

Classic loggia

A classic loggia is "built into the building" - it is an interior in which the façade has been left out and may eventually be replaced by columns or glazing.

In this case you have to technically as the bottom of the loggia flat roof consider. The flat roof rules then apply in full for the floor structure.

A difference only exists if the loggia is glazed and heated. Then it is to be regarded as an ordinary interior. For glazed but not heated loggias, the same thermal protection guidelines apply as for the flat roof, but a waterproof covering of the floor can be largely used as long as the windows remain closed in the rain.

Balcony on building top or on extension

The same rules apply here as for an unheated, open loggia. The rules for flat roof waterproofing including a suitable wear layer (eg tiles on drainage mat) must be observed.

Ground level loggia

Here are additional aspects to bear, as the loggia can also come into contact with soil moisture. Depending on whether a cellar exists or not, the floor structure can be different here.

Tips & Tricks

Above all, let the heat protection always be planned by the specialist. Even small errors can lead to massive moisture damage in wide areas of the building. You should definitely avoid this.
