Thermal Insulation
Featuring low thermal conductivity of approximately 0.038‑0.043 W/(m·K), it effectively minimizes heat transfer and maintains stable indoor temperatures.
High Cost‑Performance
It delivers excellent cost‑efficiency with low costs for raw materials, transportation and on‑site installation.
Lightweight
Weighs around 10 kg/㎡, far lighter than conventional roofing materials. It lowers the building’s overall dead load, cutting expenses for foundations and structural systems.
Easy Installation
Adopting plug‑in or splice‑joint assembly for fast‑track construction, which significantly shortens project timelines. Panels can be freely cut for convenient on‑site fitting and adjustment.
High Mechanical Strength
Composed of high‑strength steel facers bonded with an EPS core, the panel offers favourable bending and compression resistance to sustain specified roof loads.
Fire‑Resistant Performance
Both facings and core material can be configured as non‑combustible options to satisfy relevant fire‑safety standards, with an oxygen index normally reaching 32.0 or higher.
Aesthetic Appeal & Long Service Life
Available in diverse colours and sharp clean profiles to satisfy varied architectural design requirements. The panels resist fading for 10‑15 years. With anti‑corrosion repainting every decade, the service life can extend beyond 35 years.
Sound Insulation
Superior sound‑insulating capacity blocks outside noise and helps create a relatively quiet indoor environment.
Eco‑Friendly Properties
EPS core material is recyclable, and no hazardous substances are emitted throughout its service life.
