We are used to seeing walling with a 5.5 centimetre high brick design. So why change? First of all, because a 7 centimetre high brick is more attractive and has a different aesthetic effect. And because we feel that a more visible brick makes for a more beautiful wall.
And also because a height of 7 centimetres allows for the use of 50 pieces per square metre instead of the usual 60, with a savings of 1/6 on materials and- above all - on laying which is the most important cost involved.
