Insulation Materials
Dacheng County in Langfang is China's largest insulation materials base, producing rock wool, glass wool, rubber foam and foam glass at scale. Building codes in cold and hot climates alike make this one of the most stable demand categories we handle.
Typical specifications we quote
Specifications are indicative. Final ranges depend on the factory and your application — tell us the requirement and we will confirm what is actually available.
What to check before you order
- → Density drives both price and performance. State the required density in kg/m³ rather than asking for "rock wool board".
- → For building projects in cold climates, check the fire classification and thermal conductivity requirement in the local code before ordering.
- → Insulation is bulky and light — freight often matters more than unit price. Ask for a consolidated loading plan with other goods.
- → Confirm whether the facing needs to be factory-applied. On-site facing is slower and usually looks worse.
Minimum order
Usually one 40HQ container per product type for export pricing to make sense.
Lead time
15–30 days depending on density and facing.
Shipping from

Can I see the factory before ordering?
Yes. We arrange live video factory tours over WeChat, and if you need it we run real-time video spot-checks of the finished goods.
