A structural wall unit system includes a plurality of wall units having at least one face being a rotational tessellation. The face has at least two irregular sides extending therefrom. Each side of the wall units have at least one spacer or connector configured to engage other wall units. The structural wall unit system also includes a plurality of starter course units, where each starter course unit has a portion of a primary rotational tessellation element having at least one irregularly shaped side that is an image of the first side or the third side. Each irregularly shaped side of the starter course units have at least one spacer or connector configured to engage the wall units, and the starter course units have at least one straight side. The starter course units and the wall units are configured for assembly as a structural wall having a natural, random appearance.

A thermoinsulating tile for combustion chambers of gas turbines comprises: a thermoinsulating material body having a first face and a second face; a sealed chamber encapsulated in the thermoinsulating material body between the first face and the second face and containing a marker substance in the liquid state at least at a temperature of use of the thermoinsulating tile.

A hearth pad for live ember protecting a floor. The hearth pad comprises a backing for being placed onto the floor. The backing is made of a flexible sheet material. A plurality of tiles is disposed on the backing and adhered thereto using a flexible adhesive. The tiles are made of a rigid material. A flexible filler is disposed in gaps between adjacent tiles.

Disclosed is a tile unit (10) that includes a resin net (20), a plurality of tiles (30) disposed on a front side of the resin net, and a magnet sheet (40) disposed on a back side of the resin net, with the tiles being bonded and fixed to the magnet sheet with the resin net interposed therebetween.
