    摘要: A dual-reinforced construction board is disclosed comprising a core having an upper surface and an opposing lower surface, a first reinforced fibrous facer adhered to the upper surface of the core and a second fibrous facer adhered to the lower surface of the core. Each of the first and second fibrous facer comprise a non-woven mat coated on a first surface with a coating composition. The first fibrous facer and optionally the second fibrous facer further include a reinforcement layer adhered to at least a portion of the first surface of the non-woven mat. The dual-reinforced construction board has a fastener pull-through strength of at least 400 lbf.

    摘要: An acoustically insulated machine including a source of noise positioned within a housing, a first insulation member positioned within the housing and including a first porous sound absorbing layer and a first dense layer, and a second insulation member positioned within the housing and including a second porous sound absorbing layer and a second dense layer. The first insulation member being is positioned closer to the internal source of noise than the second insulation member and the first insulation member being spaced apart from the second insulation member such that an air gap is formed between the first insulation member and the second insulation member.
