Premium options for energy-efficient masonry and partitions
Welcome to the [name] category — a carefully selected range of lightweight concrete blocks designed for modern construction. Here you will find aerated autoclaved concrete (AAC) blocks, lightweight aggregate blocks, foam and cellular concrete units, and specialty insulating blocks. Each product is described with technical parameters such as density, compressive strength, thermal conductivity and recommended applications, so both professionals and DIY builders can make informed choices.
Types and variants
Light concrete blocks come in several formats to suit different structural and thermal requirements. Typical variants include:
- Aerated autoclaved concrete (AAC) blocks — highly insulating, precise dimensions, easy to cut and lay.
- Lightweight aggregate concrete blocks — made with expanded clay, pumice or perlite for reduced weight and improved strength.
- Foam or cellular concrete blocks — good for non-load-bearing partitions and sound insulation.
- Hollow and solid blocks — hollow units reduce weight and improve insulation, solid units offer higher load-bearing capacity.
- Specialty insulated blocks — factory-integrated insulation or composite units for rapid thermal performance.
Key technical parameters
- Density classes (kg/m³) — affect weight and thermal performance.
- Compressive strength — choose according to load-bearing needs.
- Thermal conductivity — lower values mean better insulation.
- Frost and moisture resistance — important for external walls and humid environments.
Where they are used
[name] products are suitable for a wide range of construction tasks:
- Exterior load-bearing walls and energy-efficient envelope systems.
- Internal partition walls for residential and commercial buildings.
- Basement and foundation walling where lightweight insulation is required.
- Renovation projects and extensions where speed and ease of handling are priorities.
Thanks to good thermal performance and dimensional accuracy, these blocks are popular in low-energy houses and multi-storey construction alike.
How to choose the right block
Selecting the correct block depends on the project requirements. Follow these practical guidelines:
- Define the structural role: load-bearing or partition. Choose a strength class accordingly.
- Consider thermal needs: evaluate required U-values and pick blocks with suitable thermal conductivity.
- Check sizes and tolerances: accurate dimensions reduce mortar use and speed up installation.
- Assess moisture exposure: opt for frost-resistant and low-absorption blocks for external walls.
- Factor in finishing: some blocks accept plaster directly; others need additional render or cladding.

What are Light concrete blocks and where are they used?
Light concrete blocks are aerated autoclaved concrete (AAC) and foam/cellular concrete units used for external walls, internal partitions and thermal insulation. They come in various densities, compressive strengths and thermal conductivities, are easy to cut and lay with adhesive or mortar, suitable for homes and commercial projects.
How to choose block density and grade for an external wall?
For external walls choose AAC or lightweight blocks with density/grade matching load-bearing needs—commonly equivalent to D500–D700 for structural walls; lower density improves insulation. Consider wall thickness, required U-value and local climate when selecting block density and compressive strength.
What's the difference between aerated autoclaved concrete (AAC) and foam concrete?
AAC blocks are autoclaved, dimensionally precise and highly insulating, ideal for neat masonry; foam/concrete blocks vary more in density and strength. AAC is preferred for better insulation and easier cutting, while foam concrete offers a broader range of properties and can be more economical.
What block sizes are available and how to choose the right one?
Common sizes in the range include 200×200×600 mm and 150×200×600 mm, plus lintels and SILLUS elements in various lengths. Choose 600 mm length blocks for faster build-up; smaller height or specialised SILLUS units are best for precise openings and lintels.
Do I need special adhesive or can I use cement mortar?
Special thin-bed adhesive formulated for aerated concrete is recommended for lightweight blocks to achieve thin joints and better insulation, though cement-sand mortar can be used for thicker joints. Thin-bed adhesive reduces material use and thermal bridging at joints.
Which accessories and finishing products are needed for block work?
You will need AAC adhesive/mortar, reinforcing mesh and profiles for joints; for finishing use BAUROC PRIMER 10L, BAUROC VIIMISTLUSKROHV or KERGALUSKROHV renders and BAUROC PAHTEL 25KG filler. Mounting tools and adhesive trowels are also recommended.
What is the thermal conductivity and are these blocks suitable for energy-efficient homes?
Thermal conductivity varies by density; AAC blocks in the category offer low thermal conductivity and good insulation, making them suitable for energy-efficient homes. Achieve target U-values by selecting the correct block density and wall thickness.
Can these blocks be used for internal partitions and which to choose?
Yes, lightweight concrete blocks are suitable for internal partitions; select thinner blocks of 100–150 mm and lower density. For improved sound insulation choose acoustic products such as BAUROC ACOUSTIC 100×200×600 or 150×200×600.
Which blocks are best for load-bearing walls and are SILLUS elements available?
Use higher-density, higher-strength blocks for load-bearing walls; the range includes factory lintels and SILLUS beam elements (e.g. SILLUS 500×400×2000, SILLUS 250×600×6000) for openings and structural support.
How to cut and process blocks on site?
Cut AAC and foam blocks with a handsaw for aerated concrete, power saws with appropriate blades or mechanical cutters; use a straightedge and spirit level for accuracy. Finish surfaces with BAUROC PAHTEL 25KG and prime with BAUROC PRIMER 10L before rendering.
What sound insulation solutions are offered in the category?
The range includes BAUROC ACOUSTIC blocks (100×200×600 and 150×200×600) designed for improved sound insulation. For best acoustic performance combine acoustic blocks with reinforcing mesh and appropriate finishes.
