Energy-Saving EPS Foam Sandwich Wall Panels for Roofing & Exterior Walls

Product Introduction

Our EPS (Expanded Polystyrene) Foam Sandwich Panels are engineered for superior thermal insulation, lightweight durability, and rapid installation—making them the ideal choice for modern energy-efficient roofing and exterior walls. These panels feature a three-layer composite structure: high-strength outer surfaces (metal/cement fiber) bonded to a fire-resistant EPS foam core, delivering exceptional heat preservation, soundproofing, and weather resistance. Perfect for residential, commercial, and industrial projects seeking cost-effective, eco-friendly building solutions.
