★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.

?Frequently Asked Questions
What is an EPS Cement Sandwich Panel?
It is a composite panel composed of two layers of fiber cement boards or calcium silicate boards sandwiching an expanded polystyrene (EPS) core material. It is lightweight, fire-resistant, and widely used for walls and partitions.
What are the main advantages of these panels?
Key benefits include high strength-to-weight ratio (1/10 the weight of bricks), superior thermal and acoustic insulation, Class A fire rating, and rapid installation that significantly reduces labor costs.
Are EPS panels environmentally friendly?
Yes. The materials are recyclable, and the production process releases no toxic substances, with significantly lower carbon emissions compared to traditional brick or concrete construction.
What is the expected service life?
Under normal conditions and proper installation, the panels have a service life of over 30 years.
Can the panels support heavy wall-mounted objects?
Yes, with preinstalled steel anchors, the panels can support loads up to 30kg/m², such as shelves, TVs, and air conditioning units.
How do they perform in terms of moisture resistance?
The cement surface layer provides good waterproofing, and the closed-cell structure of the EPS core ensures a very low water absorption rate, making them moisture-proof.
