Product Q&A

Q:Is industrial rock wool waterproof? Will humid weather affect its insulation performance?

Industrial rock wool adopts high-efficiency hydrophobic formula. It is water-repellent, moisture-proof and mildew-proof. Its thermal insulation performance remains stable even in humid workshops and outdoor environments.

Q:Is agricultural rock wool hydrophilic? Does it need soaking before use?

It adopts professional hydrophilic binder with fast water absorption and good water-locking performance. It fits drip irrigation and hydroponic systems, and can be used after simple soaking activation.

Q:What is the difference in customization process between industrial and agricultural rock wool?

Industrial rock wool is produced directly into large sheets with optional foil covering and simple cutting. Agricultural rock wool needs secondary precise cutting into small blocks and plugs to avoid fiber debris.

Q:Can I use industrial rockwool for planting?

Absolutely not. Agricultural rockwool is specially designed for high water retention and breathability, and is sterilized. Industrial rockwool contains binders and dust oils that will harm plant roots and cause rotting.

Q:Can industrial rock wool be cut into small pieces to wrap around pipes?

The sheet material has good toughness and can be cut at will. It can also be processed into strips for insulation. It is suitable for the special-shaped insulation construction of steam pipelines and boiler equipment.
