performance description            
1:The flame resistance level reaches level A, which has improved the overall fireproof performance pf steel buildings,
2:the two edges of the tongue-and-groove are filled with polyurethane foams, which effectively stop heat conduction and rain leakage prevents the reduction of strength and thermal insulation performance caused by moisture absorption and makes fireproof and thermal insulation performance more durable.
3:the high volumetric weight core material guarantees better thermal insulation performance (the volumetric weight of rock wool core material.120kg/m3, the volumetric of glass wool .64kg/m3) the two edges of the tongue-and-groove is filled with rigid polyurethane foams to improve the overall strength and prevent deformation of the tongue-groove.
4:the fireproof wool rotates 90 so that the wool fiber is perpendicular to the panel and the strength of pressure and tension resistance increases by 50.

Insulation Effect - Compared with different core materials         

Materials Name	Density(kg/m3)	Heat Transfer Coefficient (w/m2.k)	The thickness required to achieve the same energy-saving effect(mm)
Polyurethane	40	0.43	35
Rockwool	120	0.69	60
Brick	1600	0.81	475
Concrete	2300	1.75	1075

Remark: normal temperature status
Compared with other building materials, the PU sandwich panel can effectively prevent cold energy transmission due to the larger temperature difference between the inside and the outside, so cold storages are more energy-saving and the working efficiency of cold rooms is improved.

Why choose PU/PIR                                                 
1. Low thermal conductivity of≤0.020. It has a high-efficient thermal insulation effect.
2. A high percentage of close area ≥90% and low moisture absorption ≤3%. It has an excellent waterproof effect.
3. It adopts the unique concave-convex type which improves the tightness of the socket of the panel. High viscosity, high strength≥220 and good load resistance performance≥2450.
4. Excellent flame-resistance level B.
5. Wide scope of temperature resistance.
6. The panel is even and stable.
7. The dimensional stability is good≤2.
8. It is a green and environmental-friendly product.
9. Easy and convenient construction.
10. Fast and quick installation.
