Triangular blocks make only in one size of 172х172х236х80 mm. Numerical values are deciphered as height-length-hypotenuse-width.
The weight of walls and partition depends on option of mounting of glass blocks. If it is carried out by means of glue mix, only the weight of products which depends on their dimensions is considered. For example, the standard block of 240х240х80 mm will weigh 4.1 kg, product of 190х190х80 mm – 2.5 kg. The weight of their halves will be twice less.
