The system to make the angle has been designed to be as simple and fast as possible, minimizing special parts. For example, with the 200×150 angle, at the 20 cm side of the internal angle, the following are used on the outside:
· the R600 panel for 40 cm walls;
· the R500 panel for 30 cm walls;
· the R400 panel for 20 cm walls;
inverting the 200×150 internal angle, at the 15 cm side, the following are used:
· the R600 panel for 45 cm walls;
· the R500 panel for 35 cm walls;
· the R400 panel for 25 cm walls;
