1. What is Aluminum Sandwich Panel?

Aluminum Sandwich Panel is a specific kind of insulated product that is comprised of three main layers as an insulated core region that is sandwiched between two metallic aluminum facings.

The core region is constructed with low dense insulated material as mineral wool, polyurethane, polystyrene, extended polystyrene (EPS). Different insulating materials have different features and are selected according to the application requirements.

PUR and PIR are leading core materials renowned for their low thermal conductivity, heat insulation, and versatility. The core region of the panel is configured to bear the shear.

Aluminum facings are thinly layered but with high rigidity and stiffness configured to bear the bending loads. It is used for cladding, heat/ cold insulation in buildings, hotels, aircraft, and air plans construction for lower weightage, etc.

2. What are the Main Components of an Aluminum Sandwich Panel?

Aluminum Sandwich Panel consists of 3 basic layers as

• Two layers of aluminum sheets on the top & bottom sides.

• A core layer of foam or honeycomb-like comb core.

The core region is light weighted for compressibility, shear resistance, and heat insulation.

Sandwich panel skins are the outermost layers that are manufactured by a variety of materials. Aluminum is commonly used for facings.

Facings can be fabricated by using different finishing and coating materials. Fabricating material enhances the working capability and resistivity of the panel.

3. What are the Key Features of an Aluminum Sandwich Panel?

Superb Decoration

The Aluminum Sandwich Panel is featured with an attractive surface having diverse colors or pattern finishing, best looking for many decoration applications as hotel rooms.

Durability

Best anti-corrosion properties, longer life span. Don’t get rust like steel or get rust easily making the panel more durable.

Thermal Insulation and light Weight

Different types of core materials for insulation with lighter weight as foam or honeycomb core.

PUR has heat insulation and fireproofing, XPS and EPS are with thermal & sound insulation while Rockwool is fireproof & soundproof.

Economical

Aluminum Sandwich Panel with foam core is more economic in cost as compared to thick panel because here the aluminum skin generally is thick with more aluminum consumption

Flat-Panel Surface

The Aluminum Sandwich Panel is featured with a flat panel and does not have any oil canning difficulty.

Easy Fabrication

Easily fabricated with metal facings and finishing paints for corrosion resistance. Easy to cut the foam panel with the help of saws/ blades / CNC cutting machines.

Easy Cleaning

By using different cleaning materials available easily for panel cleaning.

4. How an Aluminum Sandwich Panel is Fabricated?

An Aluminum Sandwich Panel is fabricated with aluminum facings both on the upper and lower sides of the panel.

Different insulating materials are being used inside the facings for waterproof, heat insulation, combustion prevention, and compressibility.

Fabricated facings increase the stability of the panel to endure weight load and bending characteristics.

The insulation material that is used for facings can be polystyrene, polyurethane foam, and rock wool. The strength of the panel depends on fabrication. The greater the fabrication, the greater will be the strengthening.

5. How Many Types of Core can be used for Manufacturing of an Aluminum Sandwich Panel?

Aluminum Sandwich Panel consists of two facings and one core region.

Facings are made of aluminum with different coatings but the core region can be changed according to the application requirements as given below:

IPN-Isoprene Core

IPN is a refined foam core that is also known as refined PIR foam.

When it is exposed to fire, the exposed char protects the remaining core from heat damages. It has a high status of internal spacing and a good performance against fire.

PIR Core

It is a type of polyurethane core with high shear capacity. It prevents the whole core from fire or combustion by its exposed char portion. So a panel with a PIR core is most protective and stable than a PUR core.

PUR Core

It is denoted as the B-3 class among core varieties. PUR is a rigid core, do participate in fire emergency but it has less resistance against fire as IPN and PIR cores.

PUR doesn’t produce foam droplets during combustion but emits enough smoke.

Polystyrene Core

It discharges a lot amount of black smoke and heat during fire due to its heat-resistant features. With the whole core melting by fire, it can spread inside the whole panel.

Polystyrene starts to melt at temperatures below 180 degrees Celsius and produces flaming droplets.

Aluminum Sandwich Panel with polystyrene core is preferred to use in industries having high damaging risk by heating.

6. Which Material is used for Coating of an Aluminum Sandwich Panel?

Different types of coating materials can be used for the protection of the Aluminum Sandwich Panel from corrosion.

The coating type is being selected based on the buildings, applications, or specific structure for which you are using a panel. Different coating types are given below:

Polyurethane

Polyurethane Coating has high corrosion resistance. It provides a thickness of about 20 to 25micrmeter and great stability.

Plastisol Coating:

It is highly resistant to humidity and corrosion. It provides greater stability as compared to other coatings. The coating can vary due to its vast variety. Mostly 100 and 120μm thickness of plastisol coating is most preferable to use.

PVC Coating:

For lamination of metal as aluminum facings of Aluminum Sandwich Panel, PVC coating is being used. Its thickness ranges from 120-800μm.

The PVC coating is a strong and highly resistant coating against humidity and rusting. This coating provides an alluring look due to its alternative texture and feature.

Polyester Coating

Its coating thickness ranges from 20 to 25μm. It is renowned for its distinctive stability, resistance against humidity, corrosion, abrasion, and impact.

Its usage depends upon the application and its performance efficiency.

PVDF Coating

PVDF coating thickness ranges from 25 to 28μm. It has resistive capability against corrosion, abrasion, impact, and chalking, etc.

But it shows less resistance against scratch with the limited amount of gloss and coloring option.

7. What is Aluminum Sandwich Panel used for?

Aluminum Sandwich Panel is an insulating product that is renowned for its diverse featuring.

This light weightage feature configuring bending capability and shear resistance of panel is used for different purposes as:
