Poroton Porous Bricks: Your Complete DIY Guide to Thermal & Structural Wall 2026

Poroton, also known as porous brick, is a specially engineered clay block designed for load-bearing walls in buildings up to 4/5 stories high. It offers excellent thermal resistance, vapor permeability, sound absorption, and fire resistance. These blocks are available in various thicknesses, allowing you to build walls from 10 to 38 cm, even in seismic zones (for thicknesses above 20 cm). Porous bricks provide a real defense in case of fire and are ideal for use as firewalls in garage partitions. Their particular structure, dimensions, vertical-hole laying method, and significant mass give the wall high rigidity and strength, allowing for secure fixing of shelves, hooks, etc., making installation fast and easy while ensuring great workability when creating channels for utilities. Using porous blocks meets the now widespread need to improve the intrinsic characteristics of internal partitions between rooms and the performance of double external infill walls.

Different Applications for Poroton Blocks

• Thin-web porous clay block for load-bearing masonry with high thermal performance. For related home improvement supplies, check our curated selection.
• Porous clay block designed to facilitate the creation of channels for utilities.
• Partition block made of porous clay, featuring interlocking vertical joints.

How to Lay Porous Bricks (Poroton)

Laying Poroton blocks is a straightforward process, especially with the right tools and materials. Here is the step-by-step method:

1. Proceed to lay the first course on the base mortar bed, ensuring the elements are leveled.
2. Prepare the adhesive by mixing the product with water (dosage about 6-7 liters of water per 25 kg of product).
3. The adhesive is designed to adhere perfectly to the block, forming a thin layer over the entire surface of the element. To achieve this, simply dip the block a few millimeters into a basin containing the prepared adhesive.
4. The blocks are laid quickly, staggered by about half their length. For a comfortable workspace, consider durable work surfaces from our collection.

Poroton Blocks Are Ideal for Insulation

Thanks to their porous structure, these blocks provide superior thermal insulation, reducing energy costs for heating and cooling. The material's vapor permeability also helps regulate indoor humidity, creating a healthier living environment.

Pre-Engraved Channels

Many Poroton blocks come with pre-engraved channels or are easily workable for running electrical and plumbing systems. This feature saves significant time and labor during construction. For organizing your tools and hardware during such projects, a shelving unit can be a great addition to your workshop.

Insulated Bricks

Some variants of Poroton blocks include integrated insulation materials, such as mineral wool or EPS, within their cavities. These insulated bricks offer even higher thermal performance in a single, easy-to-lay element. If you are working on an outdoor project like a garden wall or shed, consider complementing it with pre-built sheds for additional storage.

Frequently Asked Questions (FAQ)

What is the difference between Poroton and traditional bricks?

Poroton bricks are lighter, have better thermal insulation properties due to their porous structure, and are designed for faster laying with thin-joint adhesives compared to traditional clay bricks.

Can Poroton blocks be used for exterior walls?

Yes, absolutely. They are excellent for both load-bearing and non-load-bearing exterior walls, providing good thermal performance. For exterior finishing, you might also be interested in outdoor lighting to highlight your new wall.

What tools are needed for laying Poroton blocks?

You will need a mixing drill, a bucket for adhesive, a spirit level, a rubber mallet, and a brick saw or grinder for cutting. For general home improvement tools, browse our selection.

Are Poroton blocks environmentally friendly?

Yes, they are made from natural clay and are fully recyclable. Their high thermal efficiency also reduces the energy consumption of the building, lowering its carbon footprint.

Can I hang heavy items on a Poroton wall?

Yes, the blocks have good mechanical strength. For heavy items like kitchen cabinets or shelves, use appropriate wall plugs designed for porous materials. For organizing your kitchen, consider a kitchen island for extra counter space.
