FREQUENTLY ASKED QUESTIONS

We use an insulation material called glass wool, which is made from glass fibers arranged using a binder into a texture similar to wool. These layers are then pressed together for increased strength and stability. Glass wool is an effective sound absorber as it traps sound waves in small pockets of air between the fibers. In contrast, dense, solid, and impermeable materials reflect sound.

The glass wool we use poses no risk to human health, the environment and contains no formaldehyde. Our acoustic products are covered with a tightly woven polyester fabric that prevents glass fibers from being released into the air. In the unlikely event of accidently inhaling glasswoool there is a possibility of minor irritation to the respiratory system. Potential symptoms include a sore throat and cough. While uncomfortable, these symptoms are temporary and easily treated.

We use 24 kg/m³ density glass wool in our standard acoustic panels, providing our customers with an optimal price-to-performance ratio. If you are looking to treat specific frequencies, we offer higher-density acoustic panels at 48 kg/m³.

A good guideline to follow is to cover 10%-20% of your wall surface area. To obtain optimal results you may need roughly 40% coverage. In other cases, you might only need to install a few panels that are positioned strategically. The number of acoustic panels needed largely depends on your specific goals. Factors such as the room layout, construction materials, seating arrangement, and window placement all play a significant role. Additionally, the room's intended use matters—acoustic treatment for recording studios differs greatly from that of conference rooms or restaurants. Feel free to reach out for a more accurate estimation that aligns with your acoustic needs.

Generally, most panels should be centered roughly around your ear or tweeter height. Hoewever this can vary depending on the frequencies and reflection points you wish to target

No, our acoustic products are not designed to isolate or reduce sound transmission. They are intended to enhance the sound quality within a room by absorbing sound waves that would otherwise bounce around. For effective soundproofing, construction adjustments are typically required.

No, our bass traps absorbs high, mid and low frequencies. Providing a full range of absorption across the entire frequency spectrum. The effectiveness of bass traps also depends heavily on placement. Bass traps are most effective when placed in room corners, as this is where low-frequency sound tends to concentrate. Installing them along walls or in corners where sound waves naturally build up will maximize their performance.
