The sandwich panel system is a type of construction system that consists of three layers - two outer layers and a core material sandwiched in between.
The outer layers are typically made of metal, such as steel or aluminum, while the core material can be made of various materials like polyurethane (PU), polystyrene (EPS), rock wool, or mineral wool.
PU (Polyurethane) and PIR (Polyisocyanurate) are both types of insulation materials commonly used in construction. PIR offers improved fire resistance and thermal stability compared to PU, making it suitable for applications where these properties are critical.
The main differences between PVDF and PE-coated steel lie in their durability, weather resistance, and application suitability.
PVDF coating is more durable and weather-resistant, while PE coating is more cost-effective and suitable for indoor applications.
Non-combustible materials (Class A): are the highest fireproof grade and do not contribute to the spread of fire.
Fire-retardant materials(Class B): are designed to slow down the spread of fire and reduce its intensity.
