During edition of partition the User can open the list of building materials using the button „Select material from list” located in material name field. A window for selection of building materials will appear, which includes list of materials, which can be used by the User during defining of partition.

Description of columns in table:

Name of material or material group

At specific building material the field can be completed with a value, which has been declared by the User in building materials edition window (see chapter 4.6), otherwise declared in program values of “d” for building materials will remain not completed.

r – building material thickness

Defines material thickness in dry condition

l – thermal conductivity coefficient of building material

For specific material, depending on grade of humidity. Specified automatically by the program for a building material selected from the list.

Cp – specific heat of building material

Defines specific heat of material in dry condition.

m – Vapour diffusion resistance coefficient of building material

Value completed automatically depending on building material properties.

R – thermal resistance of partition layer

Field not completed. Value given by the User or calculated in partition table.

The User can change the content of list selecting following fields:

- Show aerial layers first – selecting this field will cause displaying of aerial layers groups as first on the list of building materials,

- Enter initial letters of searched material – a field for tipping of initial letters or complete name of building material searched on the material list.

- Alphabetical view – selection of this field will cause displaying of building materials as a list arranged in alphabetical order,

- Group view – selection of this field will cause displaying of building materials in groups,

- Sort by… – fields for sorting of building materials according to following features: name, thickness, density, lambda coefficient, specific heat, vapour conductivity, transmission resistance.

Thermal properties of all building materials are determined for semi-humid conditions.

In the list as first group is displayed a group containing recently used materials.

There is available a mode for quick material searching. Entering of complete name or initial letters of name of searched materials in displayed field marked with cursor “Enter initial letters of searched material name” will cause its searching. Selection can be accepted by means of key Enter or by clicking OK button.

After pressing of button or key F3 for entered letter sequence the next building material complying with this entered name will be searched.

In the status line you can see displayed full name of actual selected material. This name is invisible on the list.

Operations available in material selection window:

Keyboard:

- Enter – selection of material, on which the cursor is positioned,

- Entering the initial letters of searched material name will cause its finding on the list of building materials. For example, entering the letters „st” will cause finding of material, the name of which begins with these letters, for example „stone”. Moving to next material beginning with entered letters will take place after pressing F3.

- F3 – moving to next material, the name of which begins with entered letter sequence

Mouse:

- Double clicking the left mouse button on material group – opening of selected material group to the list view,

- Single clicking the icon at the group name – opening of selected material group to the list view

- Double clicking the left mouse button on material – selection of material to edited partition.

List is not available for edition by the User. The edition is possible in options of main menu >> command „Tools/Materials edition” Ctrl+F <<
