LeierTherm 12 NF Brick - Leier

LeierTherm 12 NF is a ceramic block made from fired clay, with vertical hollows, designed for non-structural masonry works. It is recommended for partition walls, enclosure walls and infill walls in frame structures where a 12 cm masonry wall is required.

Thanks to its large dimensions and tongue-and-groove joint system, the product allows faster installation and easier alignment of the elements. The tongue-and-groove joint contributes to a cleaner and more efficient execution on site.

LeierTherm 12 NF is suitable for protected non-structural walls, especially interior masonry, where execution efficiency, wall stability and good acoustic behaviour are required. The masonry must be protected against water exposure by plastering.

The product is not intended for thin-bed mortar application.
