　　◆ Features of polyurethane

　　aluminum foil roof board

　　❖ 1. The indoor environment for livestock and poultry breeding is poor and high in ammonia content. With metallic

　　aluminum as the main metal component, aluminum foil has good corrosion resistance. Aluminum foil is also aesthetic

　　owing to its soft texture, good ductility and silvery white luster, as well as patterns which could generally be seen on its appearance.

　　❖ 2. The polyurethane roof board has four crests peaks with the spacing of 333 mm and is better in pressure resistance

　　since one more crest is added.

　　❖ 3. The four-crest aluminum foil polyurethane roof board has the characteristics of heat preservation and insulation,

　　sound insulation, flame retardance, convenient construction and high strength.

　　❖ 4. In particular, this type is low in dead weight, convenient to mount, and convenient and fast to construct.

　　❖ 5. Both budget and cost are saved.

　　❖ 6. The four-crest aluminum foil polyurethane roof board saves energy and is environmentally friendly.

　　♦ Scope of application

　　Plants for various breeding industries
