Energy conservation, environmental protection, economical heat insulting, good structure, easy-doing construction.
Wide range of profile options: smooth flat, micro-rib and embossing etc. Resulting high performance exterior walls integrated with other wall material,. Invisible screwing design and varied joint method .
Two sides of color steel , the thickness of steel can do as your order, the thickness of PU sandwich is 75mm, 100mm, 120mm, 150mm, 180mm, 200mm.
Feature: Good -quality color steel or aluminum foil board, filled with high-density polyurethane (The density can reach 40kg/m3) .
Rigid Polyurethane is till now the worldly recognized best insulated material for building.
Features
1. Fire Rating. PU reaches Grade B2fire rating.
2. Heat & Sound Insulation. Temperature suitable for PU ranges from -200+150. Low Temperature Brittleness does not occur to PU sandwich panel, so it is the ideal insulated material for freezer.
3. Good chemical resistance, waterproof, anti-corrosion, insect-free etc.
4. Advanced Tech. Automatic rolling machines make the whole process of manufacture time-effective and cost-effective.
5. Easy Installation. PU sandwich panel has male and female edges to make it easier to install on site, so it saves the construction time and periord and cost. It can be pre-manufactured in factory and assembled on site, so it saves the cost of labor considerably.
