Thomson Hollow Bricks (HB4004 / HB4005): Traditional Clay Hollow Blocks for Durable & Efficient Construction

Construct smarter with Thomson Hollow Bricks (HB4004 & HB4005), high-performance hollow clay blocks from Thomson Tiles – a respected Thrissur-based manufacturer known for energy-efficient, high-quality clay products. These hollow blocks feature internal voids (hollows) that reduce weight while maintaining excellent structural strength, making them a sustainable alternative to solid bricks or concrete blocks in Kerala construction.

Made from carefully seasoned natural terracotta clay sourced from their own fields and fired to perfection, the two sizes (12x4x3 inch for thicker walls and 9x4x3 inch for standard partitions) offer versatility. The hollow design improves thermal insulation (air pockets trap heat/cold), enhances breathability to resist dampness and mold in humid climates, and allows faster curing/firing for consistent quality. They provide good mortar grip and are widely used for partitions, infills, boundary walls, and affordable housing.
