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 provides excellent insulation.
What are the main advantages over traditional bricks?
The panels weigh only 1/10 of traditional brick walls, reducing structural load. They offer superior thermal/acoustic insulation, achieve a Class A fire rating, and allow for much faster modular installation.
Is the panel moisture-proof?
Yes. The cement surface layer acts as a waterproof barrier, and the closed-cell EPS core material has a very low water absorption rate, making it suitable for humid environments.
What is the expected service life?
Under normal conditions and with proper installation, these panels can last over 50 years with minimal maintenance.
Can dimensions and colors be customized?
Absolutely. While standard thicknesses range from 50mm to 200mm, we can provide custom lengths and various surface coatings or textures like stone or wood-grain.
Can it be used in seismic (earthquake) zones?
Yes, the flexible EPS core and composite structure allow the panels to absorb vibrations, providing exceptional seismic resistance compared to rigid brick structures.
