Insulated Sandwich Panels Manufacturers

Insulated Sandwich Panels

-- Steady & Reliable Manufacturer --

Introduction

Insulated Sandwich Panels are prefabricated composite elements consisting of two outer color coated steel sheets (PPGI or PPGL) bonded to a core of insulating material. These panels offer exceptional thermal performance, structural integrity, and rapid installation, making them the cornerstone of modern, energy-efficient building envelopes. They are widely used for walls and roofing in industrial and commercial construction to provide high-level insulation, sound damping, and fire resistance.

We offer panels with various cores, including EPS (Expanded Polystyrene), PU (Polyurethane), PIR (Polyisocyanurate), and Rockwool, tailored to meet specific project thermal and fire safety requirements.

Application

  • Commercial Buildings: Office parks, retail stores, and service buildings.

  • Industrial Facilities: Factory halls, processing centers, and heavy equipment storage.

  • Cold Rooms/Freezers: Specialized panels (see Tag 14) for low-temperature environments.

  • Temporary & Modular Structures: Prefabricated housing and site offices.

Advantages

  • Exceptional Energy Savings: High R-values significantly reduce heating and cooling costs.

  • Single-Step Installation: Structure, insulation, and finish are achieved in one component, saving labor and time.

  • Superior Airtightness: Reduces air infiltration when properly sealed, enhancing thermal envelope efficiency.

  • Acoustic Performance: Rockwool and thick panels provide effective sound reduction.
