How Does Belka Provide Sound Insulation?

Effective Sound Absorption

Belka is a revolutionary cotton-based wall finish that effectively reduces noise in your home or business by absorbing sound waves. The cellulose fibers that make up Belka are specifically designed to trap sound, preventing it from traveling through the wall and into adjacent rooms. Belka's textured surface creates a larger surface area for sound to be absorbed, further enhancing Belka's soundproofing properties.

Optimal Sound Insulation At 2 mm

Just 2 mm of Belka reduces noise pollution by 60%, making it an effective solution for homes and businesses. For additional sound reduction, apply a thicker layer of Belka wall design and enjoy even more peace and quiet.

Safe and Durable Wall Design

The benefits of Belka go beyond sound insulation: Our revolutionary wall design is moisture, chemical and fire resistant, making it a safe and durable option for any interior surface. Anyone can apply Belka DIY wall design without the need for professional help, making it the most practical and cost-effective way to add sound absorption to your walls.

Benefits Beyond Sound Insulation


We designed Belka to absorb sound waves, which can improve the acoustic performance of a room. In addition to a stunning TV accent wall, you’ll enjoy better sound quality when listening to music or watching movies, just from Belka wall design.

Belka’s unique composition and texture means you don’t need to apply a thick layer to achieve up to 60% noise reduction. A thickness of 2 mm is enough to make a significant difference in your life, reducing noise pollution from adjacent rooms, traffic, or other sources.

Improved sound insulation in your home also means more privacy for you, as surrounding rooms are less likely to overhear your conversations. Combined with our unique colors, Belka is the ideal bedroom wall design for a stylish, quiet environment where you’ll truly feel at home.


Belka is a versatile soundproofing solution that enhances both residential and commercial spaces. While bedrooms and living rooms benefit from increased privacy and improved sound quality, workplaces appreciate Belka for its effective sound absorption. This reduces noise levels and improves concentration.

When you choose Belka for your walls, you’ll enjoy even more practical benefits: Belka’s cellulose structure makes it fire resistant adding another layer of protection to your home and business. What’s more, Belka’s cotton fibers are a sustainable, eco-friendly resource, making Belka the most cost-effective, green way to soundproof any room!

Enhance your interior design with Belka and enjoy a quieter living space with more privacy. Whether you’re looking for a soundproofing solution for your home or office, Belka is the most versatile and effective DIY option for a peaceful interior.
