Description

Rock wool insulation rolls gives a practical insulation layer for steel roofs, workshops, wall cavities, and large flat areas needing fire-safe fiber. It is not selected by one number only because thickness, density or grade, facing, and joint treatment all affect the finished work. When the route includes corners, flanges, hanging rods, or narrow wall spaces, the product is prepared around fire-safe roll coverage and the installation method.

Installation Notes

Check the fixing side first, then place rock wool insulation rolls from the straight section toward the special parts.

Around access doors and dampers, leave a clean opening line so later inspection does not tear the insulation.

If the route is humid or cold, seal joints carefully because small gaps can become condensation points.

FAQ

Q: How can wrong material form be avoided?

A: The order should state board, roll, blanket, tube, or wrap clearly. Similar names can still mean different installation methods.

Q: What should be watched when installing rock wool insulation rolls?

A: Keep the surface clean, avoid sharp burrs, close seams, and leave access covers or labels visible if the drawing needs them.

Q: Is facing always required?

A: Not always. Facing depends on visible surface, moisture control, fire report, and whether the material needs easier cleaning or taping.
