Wienerberger Porotherm HP 200 Hollow Clay Block: Innovative Horizontally Perforated Walling

Revolutionize your wall construction with the Wienerberger Porotherm HP 200 Hollow Clay Block, a flagship product from Wienerberger India – the world's largest producer of clay building materials. These horizontally perforated (HP) hollow clay blocks are engineered for non-load bearing infill masonry in RCC-framed structures, offering a lightweight alternative to traditional solid bricks or concrete blocks. One Porotherm HP 200 block replaces approximately 9 conventional bricks, drastically speeding up construction while reducing mortar usage, plaster needs, and overall dead load—leading to significant savings in steel and concrete for columns, beams, and foundations.
