5. Advantages of PUR sandwich panels:

1) Excellent fire performance:

It has passed the test of Italy's authoritative testing agency GIORDANO S.P.A. It meets the requirements of the fire protection standards M.I. 14/09/61 letter 91 and D.M. 30/11/83 in accordance with the standards of the International Organization for Standardization (ISO), British BS, and German DIN.

2) Good thermal insulation:

The maximum heat resistant temperature is 120 ℃ and thermal conductivity is 0.022(W/m·k).

3) Excellent waterproof function:

The hard cell closed cell rate is 90%, and the self-skin closed cell rate is 100%. Especially in the case of overall foaming, all the gaps can be blocked, and the airtightness is very good.

4) Environmental freindly:

Polyurethane is fluorine-free foaming, which guarantees its green environmental protection.

5) Stable size&High strength:

Fluorine-free foaming, uniform cell, high strength, ensuring stable overall layout.

6. Site Installation notes:

1. Before installing polyurethane wall panel and ceiling panel, check the material, type, size, performance and core material of the sandwich panel to check whether it meets the design requirements. When necessary, test the sample's properties (fire resistance, safety) without toxicity, bending strength and other properties;

2. Prior to installation, inspection and acceptance of PUR wall panel and ceiling panel shall be conducted for the concealed works on the ceiling and wall, and qualified requirements can be met before the construction of the wall panel and roof panel;

3,PU ceiling panel and wall panel in the installation of efficient filter air outlet smoke components, lamps and lanterns, thermal, speakers, door, window, tube through plate, around the hole to smooth, tight, clean, do not produce dust, gap seal with non-combustible material;.The perimeter of the inspection port is also well sealed;

5,Wall steel sandwich panel installation should be vertical, and sandwich panel roof installation should be level, board face level off, the position is correct, metope and floor, walls and roof, walls and walls intersect, top, top should have reasonable structure, ensure the sealing, prevent the CR. Play ball with rounded corners;

6. The vertical degree of panel installation is less than 1.5mm, the surface flatness is less than 1.5mm, and the height difference between plate and plate is less than 1mm;

7. After installing panels, should be protected, prevent collision damage board surface;

8. The surface of sandwich panels shall be smooth, smooth and consistent in color. The protective film on the surface of the plate shall be in good condition and shall be removed before delivery.
