Ceramic block LeierTherm 20 NF

The LeierTherm 20 NF ceramic block is a durable construction material with vertical cavities, designed for building non-load-bearing walls with a thickness of 20 cm. It is ideal for partition walls, infill walls, and framed walls in structural systems. Thanks to its internal structure, the block provides excellent thermal and acoustic insulation, reduces the overall weight of the masonry, and simplifies installation. It is compatible with traditional masonry mortar (cement–lime–sand) as well as ready-mixed mortars of at least M2.5 strength.

To enhance durability and protect the masonry from moisture, walls built with LeierTherm 20 NF blocks must be plastered. Due to the manufacturing process, the products may exhibit slight variations in surface color, without affecting their performance. The block measures 500 × 200 × 238 mm and weighs 14.9 kg, offering an optimal combination of strength, installation convenience, and effective insulating properties. It is a versatile solution suitable for residential, commercial, and industrial projects.
