3-rib Roof Sandwich Panel with Polyurethane (PUR)
The PUR sandwich roof panel with 3 ribs and micro profile is a modern and innovative building material. It combines quality and technology, and it is widely used in construction projects. These panels are known for their good looks, strength, and energy-saving properties, making them a great choice for many types of buildings.
The panel has two steel sheets (0.3–0.5 mm thick, 1090 mm or 1130 mm wide) with a polyurethane (PUR) insulation layer in the middle. The steel is coated with a polymer layer to protect against damage. The polyurethane is slow to catch fire and safe to use in construction.
Key Features
- High thermal insulation: PUR keeps heat inside in winter and blocks heat in summer, which helps reduce energy bills.
- Lightweight and strong: Easy to carry and install, but still strong enough to handle heavy loads and impact.
- Good load resistance: The 3-rib profile and micro shape give the panel more strength and a clean, modern appearance.
- Anti-corrosion: The zinc coating on the surface helps protect the panel from chemicals and moisture.
- Sound insulation: The PUR layer helps reduce outside noise and improves indoor comfort.
- Eco-friendly and safe: The polyurethane material is safe for people and meets environmental standards.
- Fire protection: The panel does not burn easily and helps stop the fire from spreading.
Benefits
- Energy efficiency: Helps save heating and cooling costs, especially in hot or cold climates.
- Durability: The panel keeps its shape and function for many years.
- Easy installation: Fast and simple to install, saving time and money on construction.
- Modern look: The ribbed micro surface gives the roof a clean and stylish appearance.
Areas of Use
- Industrial buildings: Factories, warehouses, logistics centers
- Commercial buildings: Malls, office buildings, exhibition halls
- Residential buildings: Villas, apartment buildings, private houses
- Agricultural buildings: Farms, greenhouses, animal shelters
Polyurethane (PUR) roof panels with a three-rib micro-profile have become an integral part of modern construction projects due to their high quality and long service life. Meeting both technical and aesthetic requirements, this product is driving revolutionary changes in the construction industry thanks to its wide range of applications.
