The H+H Celcon Standard Aerated Concrete Block, available in varying thicknesses and a grey color, offers remarkable versatility. These blocks serve numerous functions, acting as infill for beam and block flooring, internal and external cavity walls, solid walls, separating walls, and flanking walls. Their application extends to multi-storey buildings and foundations. Combining strength, a thermal conductivity of 0.15W/mK, and acoustic properties with the lightweight attributes of aircrete, the Celcon Block Standard Grade holds a BBA certification and boasts a robust compressive strength of 3.6N/mm2. This consistent, all-around performance ensures that the 100mm Standard Grade Celcon Block can be used uniformly throughout a construction project, avoiding on-site confusion. Notably, these blocks are water and frost resistant and achieve a fire resistance rating of Class A4, enhancing their reliability for diverse building applications.
