Product Description
Product display
Yara rock stone wool products are made from natural rock such as basalt and dolomite. The natural rock is melted into melts in cupola at a high temperature about 1500°C. And the melts lava is then pour to high speed spinners through which the melts get into fibers. After that, fibers are collected together to form the original wool mat. The original wool mats then pass through pendulum, crimping and pressing process, get into the curing oven through which the wool mats are cured and shape up to different kinds of products such as rock stone wool board, rock stone wool blanket, rock stone wool pipe section, hydroponic cube, rock stone wool strip etc with different usage.

Aluminum foils (FSK, aluglass etc.), black fiberglass nonwoven/ tissue, black fiberglass fabric, steel wire mesh,
stainless steel wire mesh, fiberglass mesh etc. can be used together with rock stone wool products.

OUR COMPANYFAQ
Q: Are you a manufacturer or a trading company? A: We are a professional manufacturer founded in 2001 with FM, CE, ISO certificates etc. Our own registered brand is Operfect and warmly welcome to visit our factory at your convenience. Q: Can you provide the sample for free? A: For small sizes, samples are free for clients, just charge a little courier fee. For customized samples, we need to charge the sample fee. Q: What's the delivery time? A: 7-15 days after receipt of advanced payment. Q: What's the payment term? A: T/T, LC. Q: What's the MOQ? A: For standard specification, just a 20GP container. Q: Which are characteristics for Rock wool and glass wool? A: (1)Rock wool can withstand temperatures up to 1000° C (1800° F), fiberglass melts is around 600° C (1100° F). (2)Rock wool density range: 40kg/m3 to 200 kg/m3, and special type is up to 560 kg/m3; Glass wool density range: 8kg/m3 to 100 kg/m3, and special type is up to 300 kg/m3; (3)Rock wool blanket size: 0.6m*5m, 1.2m*5m etc. Board size: 1.2m*0.6, 1.2m*2.4m etc. Glass wool blanket size: 1.2m*30m, 1.2m*15m etc. Board size: 1.2m*0.6m, 1.2m*2.3m etc. (4)Applications: Rock wool is widely used in civil, commercial, industrial and agricultural areas; For glass wool, it is mostly used in civil, commercial buildings; some is used in industrial area with lower temperature condition. Q: Glass wool vs Rock mineral wool for soundproofing? A: For glass wool & rock mineral wool for soundproofing and acoustics, glass wool is superior because of its longer fiber length. It's widely used as fiberglass ceiling, wall panel, suspended baffle with better acoustic performance for lower frequencies. Rock wool can also be used for as rock wool ceiling, wall panel when higher fireproof performance is needed.
