Sandwich Panels

Emaar Industries manufactures insulated sandwich panels with PIR and Rockwool cores for roof and wall applications. The appropriate panel system should be selected according to the project's thermal requirements, fire strategy, building use, structural conditions, environmental exposure, and applicable regulations. PIR and Rockwool systems serve different engineering priorities, while roof and wall panels are designed around different loading, weatherproofing, and envelope requirements.

PIR vs. Rockwool:

Primary Advantage:

High thermal insulation efficiency relative to thickness

Fire performance and non-combustible mineral insulation

Thermal Design:

Suitable where high thermal resistance with relatively low thickness is required

Suitable where thermal insulation is required together with mineral wool construction

Fire Consideration:

Fire performance depends on the tested panel assembly and certification

Rockwool core provides a non-combustible insulation material; complete system classification should still be verified

Acoustic Consideration:

Suitable for general insulated envelope applications

Particularly relevant where acoustic performance is also an important consideration

Typical Applications:

Warehouses, factories, logistics facilities, commercial buildings, food processing and temperature-controlled spaces

Industrial buildings, factories, fire-sensitive areas

Skin Material Selection

Material:

Main Benefit:

When It Makes Sense?

PPGI (Galvanized)

Strength + lower cost

General industrial projects

PPAZ (Aluzinc)

Corrosion resistance + strength

Humid / exposed environments

PPAL (Aluminium)

Very light + high corrosion resistance

Coastal projects

Aluminium normally costs more than galvanized steel, mainly because it offers lower weight and better corrosion resistance. For a coastal building, that extra cost can make sense when reducing corrosion risk and panel weight are important.

Coating Selection

Coating:

Main Point:

Typical Reason to Choose:

PE (Polyester)

Standard painted finish

Cost-effective general use

HDPE

Higher-performance coating

More demanding outdoor exposure

PVDF

Strong color and weather performance

Projects where appearance and long-term coating performance matter

PVC

Different surface protection options

Project-specific requirements

Do not select a coating only by its name. The right coating depends on the building location, UV exposure, humidity, corrosion risk, expected service life and appearance requirements.
