LeierTherm 25 NF S Brick - Leier

LeierTherm 25 NF S is an efficient ceramic block designed for 25 cm non-structural masonry. It is suitable for infill walls in frame construction, partition walls and other applications where a stable, practical and efficient ceramic masonry solution is required.

The tongue-and-groove joint system helps reduce thermal bridges at the vertical joints and makes installation easier. Compared to standard ceramic block solutions, LeierTherm 25 NF S has a significantly reduced weight, which can support easier handling and faster execution on site.

With dimensions of 380 × 250 × 188 mm, an indicative requirement of 53 pcs/m³ masonry and a pallet quantity of 60 pcs/pallet, this product is suitable for residential and commercial projects where execution speed, optimised cost and ceramic material quality matter.
