What Is Zinc Cladding?
Zinc cladding is a high-performance metal exterior wall material that integrates thermal insulation into the face and back materials.
Zinc cladding is a three-layer exterior wall material with excellent heat resistance and durability.
The surface material is painted corrosion-resistant GL-plated steel sheet (55% fused aluminum-zinc alloy-plated steel sheet), the insulation material is rigid polyurethane foam or isocyanurate foam, and the back surface material is aluminum laminated paper that reflects radiant heat.
Uses of Zinc Cladding
Zinc cladding is a metal exterior wall material used on the exterior of residential and corporate buildings, often in new construction or during remodeling.
The metal appearance blends well with both Japanese and Western-style homes.
Zinc cladding has a thickness of about 18 mm, which is due to the core insulation material, and is particularly suitable for residential applications due to its high thermal and sound insulation properties.
Principle of Zinc Cladding
The surface material of zinc cladding is a coated, highly corrosion-resistant GL-plated steel sheet, which has a zinc-rich layer surrounded by an aluminum-rich layer in a mesh-like structure.
This allows the zinc sacrificial corrosion protection and the aluminum passivation protection to function to the maximum extent, and the composition of the plating layer provides excellent corrosion resistance.
The surface material, coated high corrosion resistant GL-plated steel sheet, can demonstrate high durability even at the edge of the steel sheet.
On the other hand, the insulation used for zinc cladding is rigid polyurethane foam and isocyanurate foam, which have excellent heat and sound insulation properties.
The combination of this insulation material and the aluminum-laminated paper used for the back of the siding, which reflects radiant heat, provides a high level of thermal insulation.
Zinc cladding with thermal insulation can also be used to improve the secrecy of the house by overlaying the siding, which is also advantageous in terms of sound insulation.
The double-layer construction of the existing exterior wall and the new zinc cladding provide better thermal insulation, durability, and sound insulation.
