Thanks to its compact size and low weight, it is suitable for wall and ceiling mounting and is also a great decorative accessory. The panel offers increased absorption of sound waves that impact at an angle due to multiple passes through layers of material, and thanks to the pyramid structure also offers improved high frequency absorption. Dimensions: 50 x 50 x 5 cm. Dark Gray colour design. Product is made from fire retardant material and meets the fire standards MVSS302 and DIN4102 B2.
