Butong bubble concrete panels are made by pressing two form matrices together. How these matrices join inside the panel determine the filter effect of the panel. The panels have holes from both sides of the panel in a hexagonal pattern. Due to that the cells of the two sides of the matrix are joined, the panel will keep its uniform thickness. In its semi-hard condition, panels can easily be manipulated or cut into shape.

The panels are suitable for architectural and interior purposes, like ceilings or for vertical gardens, or can be used to make objects like lamp shades. The holes can be filled with various colours concrete, glass, or left open, depending on the requirement.

With the addition of titanium oxide in the liquid concrete, the panel will clean nitrogen oxides from polluted city environments.

Panels weigh 10-20 kg/m² depending on requested transparency and strength. Butong panels have no set dimension limit. Larger panels are possible, but must be carried out on site and will be more expensive. Panel depths vary depending on matrix and requested transparency or translucency and strength. Standard matrices have cells of 3, 6 and 10mm depth, giving panels of 6, 9, 13, 16 and 20mm.
