‘iQ-Lator’ application software

Stationary calculations acc. To DIN 4108-3

iQ-LATOR 2.0 is an innovative program for hygrothermic calculation, optimization and is used to verify multi-layer, outside wall constructions, in particular for capillary-active materials. It allows stationary calculations of multi-layer, one-dimensional constructions (walls, roofs, etc.) acc. to DIN 4108-3. In contrast to the traditional Glaser method, the calculation algorithm that is integrated in the iQ-laboratory also takes the transportation of liquid water into the account.
