How many types of sandwich roof panel are there?
Sandwich roof panel can be divided into the following categories according to the core material: rock wool sandwich panels, polyurethane foam sandwich panels, rock wool color steel sandwich panels, glass fiber sandwich panels and polystyrene EPS sandwich panels. It has the characteristics of heat insulation, heat preservation, waterproof, sound insulation, light weight, earthquake resistance, etc. Color steel sandwich panel is a new multi-functional building board. Widely used in industrial and civil steel structure buildings.
Feature of sandwich roof panel :
Exposed nails joint for convenient construction and installation. Unique design of waterproof tank effectively prevents rainwater from infiltrating and avoids cold bridge phenomenon.

The bonding strength of the polyurethane sandwich roof panel is not less than 0.09MPa, the combustion performance of the sandwich roof panel reaches B1 level, When the anti -bending loading capacity of the sandwich plate is deflection of LO/200 (the distance between the LO is the distance between the support), the bending capacity of the sandwich board is not less than 0.5kn/㎡. The effective width of the plate is usually 1000mm, and the length can be customized.
The production of polyurethane sandwich roof panel requires advanced continuous production lines. Internal and external galvanized (aluminum -plated zinc) color steel plates and middle are composite of polyurethane hard foam.
PUR sandwich roof panel are widely used in energy-saving industrial plants, civil buildings, residences, etc., with the advantages of beautiful atmosphere, energy saving and heat preservation, and long service life.
Polyurethane sandwich roof panel has the following characteristics :
1) Low thermal conductivity: The polyurethane composite panel has low thermal conductivity and good thermal insulation performance, and is the best thermal insulation material.
2) Beautiful surface appearance and easy installation
3) PU/PUR/PIR sandwich roof panel has good fire resistance
4) PUF sandwich roof panel is non-toxic and tasteless
5) Waterproof and moistureproof
