140mm Celcon H+H Standard Grade Plain Face 3.6N Block

140mm Celcon H+H Standard Grade aircrete block, measuring 440mm x 215mm x 140mm, with a plain face and compressive strength of 3.6N/mm². Produced from autoclaved aerated concrete (AAC) at a dry density of around 600kg/m³, the block combines lightweight construction with reliable strength, enabling faster build programmes and lower foundation loads without compromising compliance. With a thermal conductivity of 0.15 W/m·K, it delivers excellent insulation compared to dense concrete units, helping buildings meet energy standards cost-effectively. Its mass also improves acoustic performance, making it well suited for internal partitions and separating walls. Non-combustible (Euroclass A1) and frost-resistant, the block is safe for use both above and below DPC. Versatile in application, it can be used in cavity and solid walls, partitions, flanking walls, and beam-and-block flooring across residential, commercial, and multi-storey developments.The increased 140mm thickness provides greater load-bearing strength, improved thermal efficiency, and enhanced sound insulation compared with 100mm units.
