What is Porotherm

Offering exceptionally fast, virtually dry construction, plus high strength and thermal efficiency, Porotherm is a modern clay block structural walling system with reassuringly traditional values. A natural progression from handmade bricks to engineered blocks; it is widely used and has been proven on millions of projects for over 30 years in Europe in both domestic and commercial applications, and is ideal for use on projects from single storey to multiple-storeys.

Porotherm is a highly efficient alternative to other building materials such as timber, concrete or light steel frames and is suitable for a variety of construction applications e.g:

  • Inner leaf of brick-faced cavity walls
  • Inner & outer leaves of rendered cavity walls
  • Monolithic (single leaf) external walls
  • Infill panels within framed structures
  • Load bearing & non load bearing partition walls

A Complete System

The system comprises of Porotherm blocks in a range of different sizes along with associated components including fixings, ties, tools lintels, ring beams and DPC’s.

Cavity Wall with PlasterAdvanced adhesive technology delivers high wall strengths. The special Porotherm Bed Joint Mix is applied to horizontal joint faces using a choice of applicators to a target thickness of 1mm. This material is supplied free of charge and is delivered with the blocks.

No vertical jointing is required as the blocks feature unique interlocking edges for exceptional rigidity and this feature plus the use of the special bed joint mix results in a significant reduction in building time. Functional rather than aesthetic, Porotherm blocks are usually given a rendered external finish on monolithic single skin walls, or an outer leaf of facing brick in a double skin construction. Plaster or plasterboard finishes are normally used internally over an initial parge/skim coat for air tightness.
