The Next Generation Composite Doors -BERGMAN's uPVC Composite Entrance Door Our composite door is quite simply the future of doors,available today. Offering distinctive aesthetics, strength and security combined with the latest advances in thermal efficiency. The doors can be solid panels or they can incorporate glass, with over 100 styles available. WHAT IS SANDWICH PANEL? Sandwich Panel is a composite, lightweight structure by duly bonding two outer layers onto a core insulation material to provide higher mechanical performance in lightest possible way. The ingredients of those Sandwich panels show different mechanical properties than each other, but however the total performance of output composite brings excellent results to intended use. Nowadays, the properties of Sandwich Panels like strength, flexibility and visibility have been carefully examined and analyzed by related sciences. Those panels are widely used in many fields as an ideal building material together with usage of Extruded Poly Styrene boards inside. The structural mechanic property of the Sandwich Panel outcomes from Beam Principality of the composites, so the outer materials/layers offer tensile strength while the core material resist against pressure, and moreover the thickness of inner material keeps needed space between two layers in order to have higher moment of inertia, that is certainly brings higher strength to new system with highest possible economy and the Sandwich Panels fulfills its functions without confronting undesired plastic deformations. THE ADVANTAGE OF SANDWICH PANELS ·Lightweight construction and high strength ·Durability and long lasting to outer effects ·Max, thermal and sound performance ·Easy and fast installation, free from seasonal conditions ·Economy on workmanship and time ·Custom sized production ·Aesthetic application, rich color alternatives ·Ease of surface cleaning and maintenance.
