KLB Wabenstein with integrated insulation foam (KLB Klimaleichtblock)

The owner of this EPD shall be liable for the underlying information and evidence. The programme operator Kiwa-Ecobility Experts shall not be liable with respect to manufacturer data, life cycle assessment data and evidence.

This is a specific EPD describing KLB Wabenstein with integrated insulation foam, manufactured from lightweight aggregate concrete block (LAC block) in various formats and sizes. LAC block consists of natural aggregates, water, and hydraulic binders (cement). The product described here, with gross density classes ranging from 0.40 to 0.55 g/cm³ (400–550 kg/m³), represents all backfilled, lightweight plane blocks of this type manufactured at the plant. The manufacturing operations are carried out across two production locations, each contributing equally to production (50%). These locations include: Rünz und Hoffend GmbH Co. KG, located at Brückenstr. 56220, Urmitz, Germany Trasswerke Meurin Produktions- und Handelsgesellschaft mbH, located at Meurinstr. 1, 56645 Nickenich, Germany. Below is a summary of the manufacturing process: -Cement is added to natural lightweight aggregates (pumice). -Aggregates are stored in silos or in the open air, depending on type. -Binder and additives are stored in silos -Aggregates are dosed and premixed dry with binder. -The mixture is combined with water to form lightweight concrete. -Recycled water from the factory's water treatment plant is used. -Lightweight concrete mass is filled into steel block molds. -Cores for slots or chambers are given to molds as needed. -Blocks are compacted and released using load and vibration. -Demolded bricks are loaded onto pallets. -Bricks are transported to dry high-bay warehouse for hardening (24-36 hours). -Filling the cavities with thermal insulation foam; -Bricks are packed for commissioning after reaching sufficient strength. -Fully cured in weatherproof packaging for at least 28 days. -Delivered to construction site

KLB Wabenstein with integrated insulation foam are used as versatile building materials for masonry, including monolithic, load-bearing, and non-load-bearing exterior walls. The standard formats for these blocks feature wall thicknesses of 36.5 cm and 42.5 cm.
