One of Omni Block’s claims is that the unique design of the insulation inserts protrude below the block and thermally protect the vertical and horizontal mortar joints. Two test walls were erected using 3/8″ spacers in the place of mortar. The test wall pictured on the right is constructed with standard uninsulated 8x8x16 CMU. The test wall pictured on the left is constructed with 8x8x16 Omni Block fully insulated with both interior and exterior cell inserts.
A Halogen light was placed directly behind the Omni Block test wall and was turned on during the darkness of night. The amateur videos below show both walls. The CMU wall clearly shows that the light source was detectable on the front side of the block wall at every vertical and horizontal joint. The Omni Block wall shows virtually total darkness on the front side while the light source is directly behind. The one small bright spot is actually a reflecting glare from the camera light off the front of one of the inserts.
