Description

The porous block represents the high-tech evolution of the traditional brick. It combines the mechanical strength and secular durability of terracotta with the most modern thermal insulation needs, creating single-layer walls that often do not require an external ETICS coat.

01Microporosity and Cell Geometry

Combustible microparticles mixed into raw clay burn during firing at 1000°C, leaving spherical micro-cavities full of still air. Combined with staggered vertical cells forcing heat into a tortuous zigzag path, this virtually doubles the real insulating thickness.

02Thermal Inertia and Single-layer Solutions

Unlike dry walls, porous block masonry retains considerable mass, providing exceptional thermal phase shift. Thicker blocks allow single-layer load-bearing walls without added insulation, guaranteeing robust, breathable walls.

Usage environment

Porous blocks must be cut with diamond disc saws or angle grinders, never with percussion. Mortar joints can be thin-bed (1-3 mm) for rectified blocks, guaranteeing thermal continuity without mortar bridges.
