Advantages of rock wool color steel plate sun room:
I. Excellent fire resistance: the raw materials, production technology and formula selected by rock wool laminboard make it have excellent fire resistance.
2. Good thermal insulation: rock wool laminboard of the thermal insulation is calculated based on the thermal conductivity of rock wool & lambda;= 0.043W/m2K and the thickness of the rock wool core material of the corresponding share, fire level: Class A
3. Significant sound insulation and sound absorption:
Sound absorption: rock wool laminboard together has excellent sound absorption function, which can absorb static and dynamic movements in a wide frequency range. According to the ISO354/85 specification, rock wool laminboard sound absorption function level reaches DELTALA = 15.7dB(A).
Sound insulation: rock wool laminboard has a significant reduction in noise transmission, especially suitable for local places with designated flights. In addition, after rock wool roof sheathing was selected, the rain and hail impacted the roof steel plate of the building, resulting in indoor movement and movement, which was also significantly weakened.
After testing, according to ISO717/82 and UNI8270/7 specifications, the sandwich board with a density of 100kg/m3 Rock wool as the core material is selected, and the sound insulation effect can reach RW = 29 ~ 30dB.
