Building Strong and Sustainable Walls with Silka

Silka, the world’s leading brand for calcium silicate building materials, offers a wide range of wall elements and kicker course blocks designed to provide strength, durability, and flexibility for modern construction projects. From residential homes to commercial buildings, Silka products ensure quiet, energy-efficient, and sustainable structures.

Silka Wall Elements
Silka wall elements are engineered for load-bearing performance and acoustic comfort. Their thickness and compressive strength can be matched to the specific needs of a project, allowing builders to optimize both structural integrity and space efficiency. Some of the popular Silka wall elements include:

  • E 214/643 – W = 214 mm, fb = 28 MPa

  • E 150/643 – W = 150 mm, fb = 28 MPa

  • E 100/543 – W = 100 mm, fb = 20 MPa

  • E 175/643 – W = 175 mm, fb = 28 MPa

  • E 300/543 – W = 300 mm, fb = 20 MPa

These elements are designed to provide excellent load-bearing capacity, thermal insulation, and soundproofing, ensuring comfortable and safe indoor environments.

Silka Kicker Course Blocks
Kicker course blocks are essential for laying precise foundations and corners, enabling fast and accurate construction. Silka offers a variety of sizes and compressive strengths, such as:

  • K 214/145 – W = 214 mm, fb = 20 MPa

  • K 214/160 – W = 214 mm, fb = 20 MPa

  • K 100/085 – W = 100 mm, fb = 20 MPa

  • K 100/130 – W = 100 mm, fb = 20 MPa

  • K 100/070 – W = 100 mm, fb = 20 MPa

These blocks complement Silka wall elements, allowing builders to construct robust corners, load-bearing walls, and durable partitions with minimal effort.

Why Choose Silka
Silka products are massive, resilient, and ecologically friendly. Made from sand, lime, and water, they offer long-term durability, frost and weather resistance, and non-combustibility. With their high mass, Silka walls also excel in sound insulation, creating quiet, comfortable living spaces. In addition, Silka supports sustainable construction practices, helping reduce CO₂ emissions and promoting environmentally responsible building.

Conclusion
Whether you’re planning a single-family home, a multi-residential building, or a commercial project, Silka wall elements and kicker course blocks provide the performance, flexibility, and sustainability needed for modern construction. By combining proven materials with innovative solutions, Silka makes building easier, faster, and more reliable.

Silka Common Questions

1. What is Silka made of?
Silka is made from sand, lime, and water, forming calcium silicate—a natural, ecologically friendly, and biologically safe building material.

2. What types of Silka products are available?
Silka offers a range of wall elements and kicker course blocks in various thicknesses and compressive strengths, designed to meet different construction requirements. Popular wall elements include E 214/643, E 150/643, and E 100/543. Kicker course blocks include K 214/145, K 100/130, and K 100/070.

3. What does the “fb” value mean?
The fb indicates the characteristic compressive strength of the product, measured in megapascals (MPa). It shows how much load the block or wall element can bear.

4. What are the advantages of using Silka?

  • Excellent load-bearing capacity

  • Sound insulation for quiet indoor spaces

  • Durable and weather-resistant

  • Non-combustible and safe

  • Supports radiation protection when needed

  • Contributes to sustainable construction

5. Can Silka be used for both residential and commercial projects?
Yes. Silka products are suitable for single-family homes, multi-residential buildings, and industrial or commercial constructions.

6. How does Silka contribute to sustainability?
Silka is made from natural raw materials and supports low-carbon construction. Its products are designed for energy efficiency and durability, reducing CO₂ emissions and promoting environmentally responsible building practices.

7. Are Silka walls easy to build with?
Yes. Silka wall elements and kicker course blocks are designed for fast, accurate, and cost-effective construction. Coordinated systems and large-format products simplify the building process.

8. Does Silka provide good acoustic comfort?
Absolutely. Due to their high mass and density, Silka walls are excellent at sound insulation, creating quiet and relaxing indoor environments.

9. Can Silka be used for radiation protection?
