What are the advantages and disadvantages of sandwich panels

advantage

Rock wool sandwich panels give full play to the unique properties of rock wool core materials, and have significant effects in fire prevention, thermal insulation, sound absorption and sound insulation.

1, excellent fire performance: rock wool sandwich panels using raw materials, production processes and formula, so that it has a good fire performance. Tests have shown that it has a fire resistance of more than 1000°C. Rockwool sandwich panels have passed the test of Italian authoritative testing agency GLOROANO SPA. According to the standards of the International Organization for Standardization (ISO), British BS and German DIN, rock wool sandwich panels meet the fire protection standard M.I14/09/61 letter 91 And DM30/11/83 requirements. The test results are as follows: 1) 50mm thick rock wool sandwich panel RE130 80mm thick rock wool sandwich panel REL60 100mm thick rock wool sandwich panel REL 120

2) Good thermal insulation: The thermal insulation performance of the rockwool sandwich panel is based on the thermal conductivity of rock wool = 0.043W/m2K, and is obtained by calculating the thickness of the rockwool core material correspondingly.

3) Significant sound absorption and heat insulation effects:

Sound Insulation: Rock wool sandwich panels have a significant reduction effect on noise transmission and are particularly suitable for use by designated flights. In addition, after adopting the rock wool roofing panels, rain and hail impacted the roofing steel plate of the building and caused indoor sound, which was also significantly reduced. Through tests, according to ISO 717/82 and UNI 8270/7 standards, sandwich panels with a density of 120 kg/m&sup3 and rock wool as the core material are used, and the sound insulation effect can reach RW=29-30 dB.

Sound Absorption: The rockwool sandwich panel has excellent suction effect at the same time. It can absorb sound in a wide frequency range. According to the ISO 35/85 standard

, Rock wool sandwich panel sound performance level reached DELTA LA=15.7dB(A)..

Shortcomings

The intensity is not good enough.
