Roof Sandwich Panels

Roof Sandwich Panels are prefabricated building components made from two outer metal sheets and an insulating core, designed to provide thermal insulation, weather protection, and structural support for roofs. They’re widely used in industrial buildings, warehouses, cold storage, sports facilities, and even residential projects.

Structure

A typical roof sandwich panel consists of:

Outer sheet (usually pre-painted galvanized steel or aluminum) → provides weather resistance and strength.
Core insulation → common materials include polyurethane (PU), polyisocyanurate (PIR), expanded polystyrene (EPS), or mineral wool.
Inner sheet → also metal, sometimes with a different coating or profile for interior aesthetics and hygiene.

Key Features

Thermal Insulation – Excellent heat resistance, reducing energy costs for heating/cooling.
Weatherproof – Protects against rain, snow, UV, and wind loads.
Fire Performance – Mineral wool and PIR cores offer better fire resistance than PU or EPS.
Lightweight yet Strong – Easier installation, less load on structure.
Quick Installation – Large panel sizes with joint systems speed up construction.

Common Types

PU/PIR Roof Panels – Best for insulation and water resistance.
EPS Roof Panels – More economical but lower fire resistance.
Mineral Wool Roof Panels – Best for fireproofing and sound insulation.

Applications

Factories & warehouses
Commercial buildings
Cold rooms & storage facilities
Sports complexes
Modular housing

Advantages

Reduced construction time and cost
Long service life with minimal maintenance
Multiple color and profile options for aesthetics
Can integrate skylights, vents, and solar panels
