LeierTherm 38 S Brick - Leier

LeierTherm 38 S is a vertical hollow ceramic block designed for protected ceramic masonry walls. The product is made from fired clay, a natural and durable material widely used in construction.

Thanks to its rectangular shape, the block can be laid on either the 38 cm or 23.5 cm width, offering flexibility depending on the technical design. It is suitable for both exterior and interior masonry in residential or commercial projects.

LeierTherm 38 S can be used for structural or non-structural walls, depending on the seismic zone and the technical project. According to the Leier technical sheet, load-bearing wall use is allowed in regions with seismic acceleration ag ≤ 0.15g. In regions with ag > 0.15g, the product must be used only for non-load-bearing walls.

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

Recommendation

LeierTherm 38 S is recommended for protected 38 cm masonry where good strength and thermal performance are required. For load-bearing walls, always check the seismic zone and follow the technical project. In areas with ag > 0.15g, the product must be used only for non-load-bearing walls. For quantity estimation, use the indicative requirement of 53 pcs/m³ for 38 cm masonry.
