Description

The Air Cavity dialog window is activated exclusively when the Air Cavity EN ISO 10077-2 tool is prompted.

Fields

Name

The name of the material is determined here. The field cannot be left empty, and the selected name must be unique. You can either select an existing air cavity material of the correct type or you can create a new material with values entered into this dialog window.

Color

The material will be symbolized by this color (and hatch) in the construction.

You can only adjust the color if this is a new air cavity material.

Hatch

The material will be symbolized by this hatch (and the color) in the construction. You can only adjust the hatch if this is a new air cavity material.

You can only adjust the hatch if this is a new air cavity material.

ε1,ε2

Long-wave length emission properties of the two surfaces in the direction of the heat flux.

You can only adjust these values if a new air cavity material is present and the emission properties are not calculated by flixo (cf. option dialog  window document cavities).

Unventilated

Determines whether the air cavity is ventilated or not.

According to EN 10077-2, air cavities are unventilated when they are completely surrounded surrounded by material with exterior exposure of less than 2mm.

According to EN 10077-2, air cavities are ventilated when they have exposure greater or equal to 2mm but less than 10mm.

If the air cavity is greater than this value, then a boundary condition must be set, and the air cavity cannot be assigned a "material".

These options cannot be adjusted.

Description

Additional comments. You can only modify the description if you are creating a new air cavity material.
