Product Overview

EPS sandwich panels consist of PPGI/GI steel sheets with an EPS foam core. The panels are manufactured through continuous lamination and are used for wall, roof and partition applications in prefabricated structures.

Technical Highlight	Source Specification
Thermal conductivity	0.032–0.041 W/(m·K)
EPS density	12–20 kg/m³
Fire grade	B1/B2 - verify the applicable test standard and report before publication

Quick Decision

Project Requirement	EPS Panel Fit	Note
Temporary building / partition	Suitable	50 mm is listed in the source as a cost-focused option
Prefab house / commercial building	Suitable	75 mm is listed as a balanced option
Warehouse / workshop	Suitable	100 mm is listed as the most popular choice in the source
Higher insulation requirement	Consider thicker panel	120–150 mm options are listed
Cold storage / high fire requirement	Do not decide from thickness alone	Confirm project temperature, fire standard, core specification and test requirements

How to Choose EPS Panel Thickness

Thickness	Recommended Application in Source	Buyer Decision
50 mm	Temporary building / Partition	Cost-focused option
75 mm	Prefab house / Commercial building	Balanced performance
100 mm	Warehouse / Workshop	Most popular choice
120 mm	High insulation building	Higher insulation
150 mm	Cold climate / Cold storage	Maximum insulation in the source

Important: final thickness should be confirmed against the project's thermal, structural, fire and local-code requirements.

EPS vs Rock Wool vs PU/PIR

A comparison of EPS, rock wool and PU/PIR core materials helps you select the proper sandwich panel according to budget, thermal requirements, fire rating and application scenarios.

Factor	EPS	Rock Wool	PU/PIR
Relative cost	Lower in the source comparison	Medium	Higher in the source comparison
Thermal insulation	Good	Good	Higher in the source comparison
Weight	Light	Heavy	Light
Installation	Fast	Medium	Fast
Fire performance	Project-specific; verify test result	Generally selected where higher fire performance is required	Project-specific; verify test result
Typical application in source	Warehouse / Prefab	Fire-required projects	Cold storage
