Details

PU sealing Rock wool sandwich roofing sheet, PU double side sealing, It is also called PU sealing rock wool composite panel, PU sealing rock wool sandwich panel, PU sealing rock wool sandwich panel, new rock wool energy-saving insulation panel, new rock wool composite panel, metal surface new rock wool composite panel, etc. This is a non-combustible structural rock wool as the core material, with galvanized or aluminized zinc colored coated steel plate as the finish, both ends of the polyurethane edge, through the professional development of adhesive, the two form an interaction composite of high quality energy-saving building board. It sets fire prevention, thermal insulation, noise insulation and beautiful decoration in one. It is widely used in steel structure plant, power plant, electric power equipment company, automobile exhibition hall, cement warehouse, steel structure office, airport terminal, railway station, sports venues, large supermarkets, logistics center and other steel structure buildings.

Product Features

PU sealing Rock wool sandwich roofing sheet, the use of polyurethane products excellent water resistance to overcome the shortcomings of rock wool easy water absorption and dehydrating, in terms of physical properties effectively extend the service life of the product. It is a combination of the characteristics of polyurethane and rock wool.

1. Sealing performance:

Polyurethane double-side sealing rock wool sandwich board adopts the assembly line production process, which takes advantage of the excellent water resistance of polyurethane products to overcome the shortcomings of rock wool easy water absorption and dehumidify, and effectively extends the service life of the product in terms of physical properties.

2. Material selection

Rock wool selection of high-quality structural rock wool, rock wool are made of natural rocks and minerals as raw materials, high hydrophobic rate, low slag ball content, no asbestos, no mold.

The metal panel adopts high quality galvanized or color coated aluminum zinc steel plate as the panel, which has excellent anti-corrosion and anti-aging performance.

Binder for the international well-known multinational company professional development, strong bonding performance.

3. Process

The use of rock wool 90 degrees of the new production process, so that it and the steel plate into a vertical shape, greatly improve the compressive strength. The new rock wool composite board can be sealed with polyurethane edge to ensure good air tightness and water tightness.

The binder is distributed by spraying, the amount of which is 3 times that of conventional products, greatly increasing the bond strength.

4. Finished product

PU sealing Rock wool sandwich roofing sheet is structural rock wool in the middle, and 50mm wide polyurethane insulation material is provided on both sides from the end. It can also be made into a composite board filled with rock wool.

Core advantage

Compared to traditional rock wool board	Compare polyurethane sandwich board
✅ Edge sealing solves the problem of rock wool easy moisture absorption and joint heat leakage	✅ Make up for the lack of pure polyurethane fire rating (Class A)
✅ improve wind pressure resistance and edge strength	✅ Both thermal insulation performance and fire protection requirements
✅ Reduce installation losses (reduce field sealing)	✅ Better sound insulation
