Poly Urethane Sandwich Panel


Brief Introduction of Sandwich Panels:

PU Sandwich panel (Polyurethane sandwiched panel )is composed of 2 layers of weather-proof colored steel sheets and jetted the hard forms of polyurethane between 2 layers which feature fireproof materials. It is suitable for the various roofs and walls referring to the large-size factory buildings, storages, exhibition halls, gymnasiums, freezing stores, purifications workshops, etc, which features temp-keeping, heat insulation, weight-bearing, weatherproof with the rich colorfulness and good appearance.

Winstrongtech takes the lead in combining structural advantages with composite materials and insulation properties of inorganic materials to develop a unique sandwich wall system. The Sandwich Wall comprises two aluminum alloy panels (face panel/back panel) and a core of high-density mineral wool. This is a functional curtain wall system that integrates decoration and insulation to offer a wide variety of shapes to meet all the comprehensive requirements that modern architectural façade needs in terms of durability, aesthetics, environmental protection, energy efficiency and fire protection, etc. This product is widely used in public facilities, industrial plants, combined cooling units and many other buildings.
