Product introduction

roof sandwich panel

Roof sandwich panels are composite building materials used for roofing, offering both structural support and insulation. They consist of an insulating core sandwiched between two layers of metal sheeting, typically steel or aluminum. These panels are designed to provide thermal and acoustic insulation, weather resistance, and are often used in agricultural, industrial, and service buildings.

Optional core materials:

PU(PIR)+Rock Wool; PU(PIR)+Glass Wool; PU(PIR)

Product advantages

☆Energy Efficiency & Thermal Insulation

Excellent thermal insulation performance—twice as effective as EPS panels at the same thickness.

☆Fire Resistance

Certified by the National Center for Quality Supervision & Inspection of Fire Protection Systems and Components, meeting GB8624 B2 flame-retardant standards.

☆Air Tightness & Sound Insulation

Superior sound absorption, significantly reducing noise from rain, hail, and impacts.

☆Waterproof & Anti-Corrosion

Wide-span design with fast drainage; hidden fasteners prevent rust, extending panel lifespan.

☆Aesthetic & Cost-Effective

Sleek appearance, reduced material waste, and lower installation costs.

☆Quick Installation

Factory-produced polyurethane panels ensure consistent quality and 35+ years of proven performance, enabling fast on-site assembly.
