What is a Sandwich Panel?
A sandwich panel is a type of composite building material consisting of two layers of high-strength metal sheets (usually steel tai aluminum) bonded osoitteeseen an insulating core material in the middle. This “sandwich” structure combines lightweight design, excellent strength, thermal insulation, and durability.
It offers structural efficiency—such as superior tensile and compressive strength from the dual metal layers, while the lightweight core reduces overall weight without sacrificing load-bearing capacity—making it suitable for wide-span roofs, wall cladding, and modular buildings.
Sandwich panels also provide outstanding thermal insulation (the core effectively blocks heat transfer, reducing energy consumption), enhanced fire resistance and safety (some core materials like rock wool are fire-resistant and improve the building’s fire rating), and ease of installation (modular design enables quick and efficient assembly).
Mikä on sandwich-paneelikone?
