The Hollow clay blocks by Porotherm Smart Bricks designed to provide better efficiency, durability, ease of use and a host of other benefits that aid in cost- effective wall construction and comes in two types: Non-Load Bearing Clay Hollow Blocks and Load Bearing Clay Hollow Blocks.


Porotherm Horizontally Perforated Clay Bricks (Porotherm HP)

Porotherm HP clay hollow blocks are primarily used as infill masonry for non load bearing wall construction. The product is especially beneficial for high rise apartment buildings and has been extensively used across South India for the construction of Apartments, Independent Houses, Villas, Hospitals, Educational Institutions, Commercial Buildings and warehouses.

Porotherm Thermobricks

Porotherm Thermobrick has borrowed the principle of thermal insulation from nature, to become a unique walling material – one that keeps the interiors cool in summer and warm in winter! Specially formulated insulating material gives it a ‘U’ Value* of 0.6 W/m²K , which results in superior thermal insulation that greatly improves the indoor comfort of the building. U’ Value: 0.6 W/m2K makes Porotherm Thermobrick the best available energy efficient brick in the market.

Porotherm HP Grinded with Dryfix System

Porotherm HP Grinded is the latest addition to the Porotherm Smart Bricks family – a result of Wienerberger’s constant efforts to innovate. The product offers greater stability and comes as a combined solution with Wienerberger’s revolutionary dry mortar system- Dryfix. The Dryfix.System is a specially formulated adhesive that creates perfect bonding between the blocks specially when used with Porotherm HP G, enhancing the strength of the walls.


Porotherm Vertically Perforated Clay Hollow Bricks (Porotherm VP) for up to G+1 structures

A hallmark of design and ingenuity when it comes to cost-effective, safe and green construction practices. This new age wall solution helps you save on your steel and concrete expenditures as it allows buildings to be constructed without RCC frame structures. Ideal for up to Ground + 1 floors. The product is robust and 100% natural with thermal insulation property promoting a comfortable indoor climate all year round. High compressive strength bricks ≥ 7 N/mm2 enabling load-bearing construction. Savings of structural cost as the concept eliminates the columns.


Some of the intrinsic advantages common to all the profiles include:

  • Light weight (60% less weight than conventional walling material),
  • Strong & durable- high Compressive strength
  • Non-susceptible to carbonation thus providing greater durability
  • Excellent Thermal and Sound Insulation
  • Low water absorption of ~ 15%, thus minimal risk of dampness, cracks or shrinkage of walls
  • Technical support provided by Wienerberger at construction sites
