Abstract
Abstract An infiltration and energy barrier comprising a flexible substrate sheet having at least one metalized layer thereon is applied to a structure in a substantially continuous manner and is disposed between the structural underlayment and the finish material to enhance the energy efficiency of the structure. In accordance with the desired application, the infiltration and energy barrier may be either impermeable or vapor permeable.
