Product Description
The HBC Prefabricated EPS Interior Partition Wall is a lightweight, modular, and non-load-bearing wall system designed for fast installation in residential, commercial, and industrial interiors. Unlike traditional panels, it uses pure EPS foam core combined with a reinforced polymer-cement coating for structural stability. This product excels in flexibility, sound insulation, and cost efficiency, making it ideal for modern drywall construction.

Frequently Asked Questions
🔹 What is an EPS Cement Sandwich Panel?
It is a composite panel composed of two layers of fiber cement or calcium silicate boards sandwiching an expanded polystyrene (EPS) core. It is lightweight, fire-resistant, and provides excellent insulation.
🔹 Is this material fire-resistant?
Yes. The cement facings combined with flame-retardant EPS typically achieve a Class A fire rating, making it non-combustible and safe for various building types.
🔹 How does it compare to traditional brick walls?
It weighs only about 1/10 of traditional brick walls, significantly reducing structural load. Additionally, it offers superior thermal and acoustic insulation and much faster installation times.
🔹 Can the panels be customized in size?
Yes, we offer custom lengths (up to 6000mm) and various thicknesses (standard 50-200mm) to meet specific architectural requirements.
🔹 What is the typical service life?
Under normal conditions and with proper installation, these panels have a service life of over 30 years.
🔹 Is the EPS cement panel moisture-proof?
Yes. The cement surface layer provides good waterproofing, and the closed-cell structure of the EPS core ensures a very low water absorption rate.
