Roof Structure

Implementation: Here a name for the implementation can be assigned.

Layers:

Multiple settings can be made for each layer.

Ident number: Each layer receives a layer identification number. This identification number gives the layer a name, which is also displayed in the measurement. In addition, it assigns various information to the layer such as the texture set or data for load assumptions in structural calculations. A corresponding browser is available for selecting the identification number.

Assignment: Depending on the identifier used (see below: Z, S, I, ...) you can select a specific assignment setting for each layer. For the tile layer this is a tile assignment, for the batten layer (always automatically below the tile layer) a batten assignment, and for all other layers an assignment for determining formwork or boarding.

Thickness: The layer thicknesses are entered. When a value is changed, the total roof thickness is adjusted automatically. Layer 0 should be the primary layer (rafter layer) of the roof surface. Layers -1, -2, etc. are then on the top side, and layers 1, 2, etc. on the underside of the roof surface.

Z: The 'Z' stands for tile layer. When a layer is marked as a tile layer, this layer is also indicated as a tile layer in the measurement data. In addition, tiles can only be entered in a tile layer. When a tile layer is defined, the layer directly below it automatically becomes the batten layer. This receives a gray check mark as its identifier.

B: The 'S' stands for formwork layer. Formwork layers are output separately in the measurement report (as formwork area).

I: The 'I' stands for insulation measurement. For layers with the 'I' identifier, insulation areas and insulation volumes are output in the measurement report.

F: The 'F' stands for surface measurement. The surfaces of layers with the 'F' identifier are reported separately again in the layer measurement.

V: The 'V' stands for preserving eaves areas. Up to and including version 10, the eaves areas (= roof areas outside the exterior walls) of the core layers were not cut away from the exterior walls (see next paragraph) and the non-core layers below the core layer automatically ended at the interior side of the exterior wall. If you set the checkbox in the 'V' field, the eaves areas of these non-core layers are also preserved. Unlike the core layers, however, the strip that is penetrated by the exterior wall is cut out of the respective layer.

K: With the 'K' identifier for core layer you can influence the intersection of the layers with the walls. Core layers are not trimmed back by a wall; they always extend to the roof overhang, even if they must pass through a wall to do so. All non-core layers (= shells) below the core layers are trimmed to the inner edge of the exterior wall. All shells above the core layers extend to the roof overhang.

PL: The 'PL' identifier stands for plate. Here you can set whether a plate should be generated for the corresponding layer or not. For example, it is sensible not to generate a plate for the layer in which the rafters are entered. When visualizing, the rafters should be visible and not a plate representing the layer. For the formwork layer, on the other hand, it is sensible to generate a plate so that the formwork area is visible during visualization.

Layer areas for EnEV: This button switches to an additional dialog box for entering the layer zones that can occur in a roof surface. This dialog box is described in the chapter Layer Zones for EnEV.
