Glass Brick Energy Efficient Glass Brick with U=1.4 W/m² K. Energy efficient glass brick with thermal transmission U=1.4 W/m² K.

The Energy Saving glass bricks are produced using a patented method, in which a Low E (low-emissivity) glass sheet is inserted during the production process between the two parts that make up the glass bricks, and the empty space is filled with argon gas under pressure.

The aim is to achieve thermal insulation between the two parts of the glass brick and reduce thermal conductivity. The result is an extremely high-tech glass brick that reduces thermal transmission to U=1.4 W/m² K, which is half compared to regular glass bricks.

Its size is the classic 19x19x8cm dimension and it is available in two designs: the classic “cloud” which is also in stock, and completely transparent (without design) which is available upon order.

Of course, like all glass bricks, it can be sandblasted on one or both sides.
