1260 style light refractory brick is one of the products of Pasargad refractory materials company. It is a light heat insulation firebrick in different temperature grades from 1000 degrees Celsius to 1430 degrees. Heat-insulating refractory bricks or lightweight refractory bricks are products that are used for refractory walls in furnaces and other heating devices that are not justified by erosion and corrosion stresses, and the purpose of using them is to reduce heat loss.

With the improvement of light refractory brick quality in recent years, these products have replaced heavy bricks such as chamotte bricks, alumina and bauxite bricks, which were previously commonly used in the first layer of high temperature furnaces. This helped, in addition to reducing the heat dissipation of the furnace by 15-35% to reduce the weight of the furnace structure and thus the use of lighter facilities and ultimately reduce the price of the furnace structure, as well as the heating and cooling speed of furnaces, especially in Batch furnaces, like shuttle furnaces, fell sharply

In general, in the design of the kiln, high temperature light bricks such as kiln NG26, NG25 are used for porcelain bricks of the first layer of the kiln. Low thermal shrinkage is the most important property required of bricks to perform this part. Lower temperature groups are used to run behind the main layer. Low thermal conductivity is the most important property required for this group of bricks.

The mortar required to connect light bricks at high temperature is aluminum mortar and the mortar required to connect light bricks at low temperature is chamotte mortar. It is recommended to use Air Set Mortar hard mortar to apply the first layer of a wall with light brick. After execution, it creates sufficient strength for the wall and prevents it from falling due to small stresses.
