A ceiling system includes a ceiling support structure supporting a plurality of ceiling panels, each ceiling panel including a core layer having a top surface facing a first interior space above the ceiling panels, a bottom surface facing a second interior space below the ceiling panels, and a plurality of peripheral edges extending between the top and bottom surfaces. A top frame layer extends from the top surface and a thermal layer is on the top frame layer opposite the top surface. The thermal layer has a first surface facing away from the top frame layer and a second surface facing toward the top frame layer. The top frame layer supports the second surface in a spaced-apart manner from the top surface to form one or more air gaps between the top surface and the second surface. The first and second surfaces have a thermal emissivity of 0.5 or less.

The present invention is related to a heterogeneous composite having a first layer which includes a fiber layer, a metal layer, a plastic layer or its combination thereof, a second layer which includes a fiber layer with a plastic layer, or a fiber layer with a non-woven cloth layer, and a base layer which is a thermoplastic layer. The first layer and the second layer are respectively mounted on the base layer by a glue layer, and the compressive strength value between the first layer and the second layer is less than 20%. The base layer enhances strength of whole composite and the heterogeneous composite provides a beautiful and competitive product.
摘要:
Fabrics containing hydrophilic expanded polytetrafluoroethylene (ePTFE) fibers and at least one non-ePTFE fiber are provided. The fabric provides a combination of high breathability and controlled moisture management. In exemplary embodiments, the fabric may be a woven, knit, or fleece fabric. The fabrics contain at least 15% ePTFE fibers based on the final fabric. The hydrophilic ePTFE fibers in the fabrics may be used to control moisture such as water vapor, liquid water, or sweat within the fabric by storing the moisture within the hydrophilic ePTFE fiber network. Also, little to none of the moisture remains on the outside of the hydrophilic ePTFE fibers, making the fabric feel dry even where there is moisture therein. A polymer membrane and/or a textile may be laminated to the fabric to produce a laminated article.
