VBLOK Barrier Insulation Pad with Lead Septum, 12 Sq. Ft.

VB-3 is a multi-layered composite material which provides shock absorption, a noise penetration barrier and thermal insulation in a single product. The first (isolation) layer is constructed of closed cell neoprene foam which decouples the center layer from the source of vibration. Next, the thin lead center layer is a floating wall, which, because of its high mass and relative thinness, is one of the most effective noise penetration barrier materials available. The third, or surface layer, is also made of reinforced neoprene. This is to protect the lead center layer and to maintain a "sealed" airspace for thermal insulation. It is ideal for application over transmission tunnels and firewalls. It easily conforms to round, curved or irregular su
