Abstract
Multiple layer interlayers having enhanced optical and acoustic properties are provided, along with methods of making and using the same. Interlayers as described herein may include at least two outer skin layers and an inner core layer, with one of the outer skin layers having a different thickness than the other at one or more locations along the interlayer. The multi-layer interlayer may also exhibit acoustic properties and, in some cases, may have an overall wedged thickness profile. Additionally, in some aspects, interlayers and laminates formed therefrom may also provide reduced infrared energy transmission, without sacrificing acoustic and/or optical performance.
