Roof Sandwich Panels

Home » Product » Roof Sandwich Panels

Introduction

Roof sandwich panels, also known as sandwich roof panels, are a type of building material that consists of two layers of metal sheets as the surface layer, with a core material in the middle that has functions such as fire prevention, sound insulation, and heat preservation. It is a building material that is formed by rolling, foaming, and bonding with high-strength adhesives. It has multiple functions such as high strength, heat preservation, heat insulation, and waterproofing.

We have roof sandwich panels of various sizes, colors, and patterns, which are highly decorative, have a long service life, and are easy to install. If you have purchasing needs, please tell me the product specifications and quantity, and we will provide you with a quote within 12 hours.

What Types of Roof Sandwich Panels Can We Supply

Classification by Core Material

Glass wool sandwich panel

Features: Class A fire protection, excellent sound absorption performance (better than rock wool), low strength.
Application: Theaters, computer rooms and other scenes that require high sound/heat insulation.

Rock wool sandwich panel (RW)

Features:Class A fire protection, high temperature resistance, good sound insulation and heat insulation, low strength.
Application: Cold chain cold storage, constant temperature workshop, energy-saving roof and other thermal insulation requirements.

Polyurethane sandwich panel (PU)

Features: B1 grade fireproof material, best thermal insulation performance, high strength.
Application: Suitable for scenes with high thermal insulation requirements, such as cold chain logistics cold storage, constant temperature workshop, energy-saving roof, etc.

Polystyrene sandwich panel (EPS)

Features: B2 grade fireproof material, poor fire resistance, medium thermal insulation/strength, low cost.
Application: Temporary buildings, warehouses, and other low fire protection requirements.

Classification by Metal Sheet

Color-coated steel roof sandwich panel

Substrate: Galvanized steel and aluminum-zinc steel.
Features: Excellent corrosion resistance, rich color (PE/SMP/PVDF coating on the surface to enhance weather resistance).
Application: Industrial plants, warehouses, gymnasiums and other large-scale building roofs; prefabricated buildings, such as container houses, movable panel houses.

Stainless steel roof sandwich panel

Substrate: 304, 316, 201 stainless steel, etc., stainless steel is used on both sides in extreme environments.
Features: Excellent corrosion resistance, dust and bacteria, wear and impact resistance (higher cost).
