Product introduction

11

Curved sandwich panels are building components consisting of three layers—two rigid outer skins and a lighter core material—that are shaped to form a curve, combining structural integrity, insulation, and aesthetic versatility for features like curved facades, roofs, and walls. They are used in architecture to create visually interesting, energy-efficient designs by combining space-enclosing, supporting, and insulating functions.  

Optional core materials:

PU(PIR)+Rock Wool; PU(PIR)+Glass Wool; PU(PIR)

Product feature

Curved Geometry

Unlike standard flat panels, these are manufactured or formed into a specific curve, allowing for more dynamic and unique architectural shapes.  

Structural

The rigid skins and the core work together to provide excellent load-bearing capacity and stiffness.  

Thermal Insulation

The core material, often a foam, provides significant thermal insulation, enhancing energy efficiency.  

Aesthetic

The ability to create curves allows for distinctive and visually striking designs that are difficult to achieve with flat panels.  

Lightweight

Despite their strength, the core material significantly reduces the overall weight, making them efficient and easier to handle.  


Product application

☆Architectural Facades

They are ideal for creating curved facades on buildings, giving them a modern and energetic look.  

☆Roofs and Walls

They can be used in both roof and wall structures, including specialized corner panels, to diversify building architecture.  

Specialized Structures

Their unique properties make them suitable for applications requiring high performance, low weight, and resistance to impact loads.
