Steel Building PU PIR Sandwich Panel For Roof

PUR/PIR steel structure cladding ststem/Cold Storage/room Special materials

As the world’s best thermal insulation material, polyurethane is widely used in various fields for its excellent performance such as environmental protection and light weight, and in recent years, it has been used more and more in the cold chain industry.
Polyurethane composite panels are also called PU sandwich panels.
The composite panel with polyurethane as the core material is composed of the upper and lower layers of color steel plate and the intermediate foamed polyurethane, which adopts the world’s most advanced six-component online automatic operation mixing and pouring technology, which can complete the proportioning and mixing process of the social batching center or factory online at one time, and can be adjusted at will according to the temperature online, so as to produce a unique high-strength, energy-saving, green and environmentally friendly building panel.
Polyurethane sandwich panels are widely used in large industrial plants, cold storage, garages, mobile homes, exhibition halls, exhibition halls, gymnasiums, shopping centers, airports, power plants, villas, hospitals, strata and high-rise office buildings and other fields.

1. Advantages of roof panels

The polyurethane roofing panels are connected by concealed nails, and the board surface is tightly overlapped. The unique waterproof groove design effectively prevents rainwater from penetrating and avoids the phenomenon of cold bridges. The peak height of 40mm greatly improves the bearing capacity of the roof panel. While ensuring the thermal insulation effect of the building, it can effectively reduce the construction cost of the customer, and the roof slope can reach as low as 3%.

2. Advantages of polyurethane composite board wall panels

Concealed nail connection, no exposed screws on the surface, beautiful and smooth building wall. Extremely high flexural capacity, superior mechanical properties of wall mechanics, reducing dependence on auxiliary steel structures. Excellent thermal insulation performance, reducing the cost of indoor air conditioning in the building. A variety of appearance effects, beautiful wall.

1.What is a PU sandwich panel used for?

Sandwich panels are used as cold storage panel in buildings such as cold rooms and cold storages which requires certain air-conditioning features, based on their thermal insulation feature. Cold storage panels maintain the desired temperature and control the heating and cooling process.

2.What is the difference between PIR and PU sandwich panels?

(1) Difference in fire resistance: PU foam: generally B3 grade, by adding flame retardants, it can reach B2 grade. PIR foam: generally B2 grade, by adjusting the concentration of polyisocyanurate acid ring and other formula technology, it can reach the B1 level, and the oxygen index can reach more than 35%.

3. What is the life expectancy of a PU panel?

For example, under normal wear and tear, a durability of more than 50 years can be expected for polyurethane insulation systems for buildings, more than 25 years for polyurethane used for insulation of refrigerators or more than 20 years for the application of polyurethane in vehicle bumpers.
