Soundproofing is becoming ever more important because of the noise polluting our environment. Sheet lead is one of the basic materials for acoustic control systems, lead is an extremely efficient barrier material by itself or fastened to studs as part of a wall. Arslan Metal’s lead sheet products are widely used in different applications for sound proofing.
