Attenulead - noise control lead sheet

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.  Lead sheet can also be adhesively bonded to gypsum board or plywood. Mayco Industries is America's leading producer of sheet lead.

In general, there are three functions for describing Acoustical Control:

  1. Blocking of sound paths by barriers
  2. Damping of structures and surfaces - to reduce vibration and radiation of airborne sound
  3. Absorbing sound - usually by light fibrous materials

Attenulead has been developed to help control noise in various interior environments: hospitals, schools, office buildings, industrial plants, apartment buildings and other multi-family housing.

Advantages of Attenulead are:

High Density, Natural Limpness and Easily Adaptable.

Attenulead is generally available in 1/64" thick x 4' wide x 25' long.  Special sizes are available upon request.
