Details

PU sealing Rockwool sandwich wall, is sealing the non-combustible structure rock wool as the core material, with galvanized or aluminized zinc colored coated steel plate as the finishing surface, both ends of the polyurethane sealing edge, through the professional development of adhesive, the two form the interaction of the high quality energy-saving building plate. It integrates fire prevention, thermal insulation, noise insulation and beautiful decoration in one. Polyurethane double-side sealing rock wool sandwich board gives full play to the unique properties of rock wool core material, and has significant effects in fire prevention, thermal insulation, sound absorption and sound insulation. At the same time, it retains the advantages of polyurethane plastic, airtight, high strength and no water absorption.

Product features

(1) Excellent fire performance:Raw materials, production process and formula of PU sealing Rockwool sandwich wall make it have good fire performance. The test shows that it has a fire resistance of more than 1000℃.

(2) Good thermal insulation and insulation: The thermal insulation and insulation of the polyurethane double-sided rock wool sandwich board is based on the thermal conductivity of the rock wool λ= 0.043W/m2K, and calculated by the corresponding proportion of the thickness of the rock wool core material.

(3) Sound insulation and sound absorption effect is significant: polyurethane double-side sealing rock wool sandwich board has a significant reduction in noise transmission, especially suitable for designated flights through the place. In addition, after the rock wool roof board is used, the indoor sound caused by the impact of rain and hail on the roof steel plate of the building is also significantly weakened. According to the test, according to ISO 717/82 and UNI 8270/7 standards, the sandwich board with a density of 120kg/m3 rock wool as the core material is selected, and the sound insulation effect can reach RW=29~30 dB.

PU sealing Rockwool sandwich wall also has a good sound absorption effect, it can absorb a wide range of frequencies of sound. According to ISO 354/85, the sound absorption performance level of rock wool sandwich board reaches DELTA LA=15.7 dB(A).

Material and structural performance relation

‌ performance index ‌	‌ Material impact ‌	‌Structure optimization means ‌
‌ Fireproof performance ‌	Rock wool class A non-combustible + polyurethane flame retardant treatment	The edge sealing layer is tightly wrapped with the rock wool to delay the spread of the fire
Insulation efficiency‌	Rock wool low thermal conductivity + polyurethane banding reduces thermal bridge	Multi-layer composite + continuous seal to block air penetration
Impermeable and moisture-proof ‌	Metal substrate corrosion resistance + polyurethane closed cell construction	Falcon buckle joint + butyl tape assisted seal
‌ Mechanical strength ‌	High density rock wool (≥120kg/m³) support	Reinforcement design + high pressure composite process to improve the overall stiffness
