Rock Wool Pipe
Rock wool pipe insulation provides preformed mineral wool sections for HVAC, industrial, and building piping systems. Service temperature up to 650 °C, available for pipe diameters from DN 15 to DN 800, wall thicknesses from 20 mm to 120 mm, fire classification up to Euroclass A1 — confirm exact pipe schedule and temperature rating by inquiry. Supplied from our own and partner factories — combined capacity up to 450,000 t/yr, with a one-container MOQ and LCL support.
- Handles service temperatures that rubber foam and glass wool pipe sections cannot — the standard for industrial hot-service pipe insulation.
- Non-combustible material supports fire-rated pipe assembly documentation in risers, fire barriers, and penetration seals.
- Preformed sections provide uniform coverage and faster installation than wrapping blanket around each pipe diameter.

Problems This Product Solves
Common pain points this product is built to address.
Wrapping flat insulation around pipes wastes material and creates gaps.
Cutting flat board or blanket to fit round pipe geometry produces off-cuts, uneven joints, and thermal bridges. Pre-formed rock wool pipe sections eliminate wrapping and reduce installation waste on pipe runs.
Wrong pipe diameter means loose fit and poor thermal contact.
When the pipe section inner diameter does not match the pipe outer diameter, insulation shifts, compresses unevenly, or leaves air gaps that reduce performance. Confirming pipe OD before ordering prevents rework.
Process piping needs higher service temperatures than glass wool pipe can handle.
Steam lines, process piping, and exhaust systems operate above the practical limit of glass wool pipe sections. Rock wool pipe sections cover the higher-temperature range these applications require.
Fire-review projects require non-combustible pipe coverage.
When the specification or fire review calls for non-combustible insulation on mechanical piping, rock wool pipe sections meet that requirement without additional fire-barrier wrapping.

Engineered for Consistent Performance
Every batch is produced under controlled conditions and verified against international standards, so what you specify is what you receive — project after project.
Product Benefits
What sets this product apart in real projects.
Pre-formed pipe sections
Faster installation than wrapping flat insulation around pipes; reduces labor, waste, and gap risk.
Higher service temperature than glass wool pipe
Covers steam lines, process piping, and exhaust systems where glass wool pipe sections reach their limit.
Non-combustible mineral wool
Meets fire-review requirements for mechanical piping without additional fire-barrier wrapping.
Pre-slit option for snap-on installation
Allows single-installer fitting on accessible pipe runs, reducing crew size and scaffold time.
Density provides mechanical stability
Supports the insulation at pipe hangers and supports without excessive compression or deformation.
Faced and jacketed options available
Foil facing, wire netting, or metal jacket options can be reviewed for outdoor, weather, or vapor-barrier needs.
Best-Fit Applications
Rock Wool Pipe is most useful when pipes operate at elevated temperatures, fire-review compliance is needed, or pre-formed sections reduce installation time compared to wrapping flat insulation.
Steam lines
Pre-formed sections handle the temperature range and non-combustible requirement typical of steam distribution.
Process piping
Covers hot-service and cycling-temperature piping in chemical, petrochemical, and manufacturing facilities.
Hot water distribution
Provides thermal insulation on medium- and high-temperature hot water pipe runs in commercial and industrial buildings.
Exhaust ducting
Non-combustible mineral wool suits exhaust duct and flue pipe insulation where fire review is required.
Mechanical rooms
Pre-slit sections speed installation on dense pipe layouts in boiler rooms, pump rooms, and plant rooms.
High-temperature industrial service
Covers service temperatures above the practical range of glass wool pipe sections, confirmed by product datasheet.
Options & Variants
Choose the form that fits your application.

Foil Faced Pipe Section
Foil facing — vapor-retarder surface for weather-exposed runs.

Unfaced Pipe Section
Bare pipe section — for use under jacketing or cladding.

When It's Not the Best Fit
Rock Wool Pipe is not the best first choice for every pipe insulation condition. Review the project before selecting rock wool pipe when:
Selection Guide
Answer these to narrow down the right specification.
What is the pipe OD and service temperature?
Confirms the correct pipe section inner diameter and whether standard or high-temperature grade is needed.
What wall thickness is required?
Defines the insulation build-up for the thermal or energy calculation.
Is facing, coating, wire netting, or metal jacket required?
Determines the correct variant: foil faced, wired, or unfaced for separate cladding.
Is pre-slit installation preferred?
Confirms whether snap-on sections or standard two-half sections suit the jobsite method.

Frequently Asked Questions
Answers to common questions about this product.
Use rock wool pipe when service temperatures exceed rubber foam limits — hot water, steam-adjacent lines, and high-temperature process piping. Rubber foam is better for cold-service condensation control.
It can, but rock wool is not vapor-tight. Chilled water applications need a vapor barrier strategy — wrapping, facing, or sealant. For integrated vapor resistance, consider rubber foam pipe.
Standard sections require sliding over the pipe end during installation. Pre-slit sections open to wrap around installed pipes for retrofit work without disconnection.
Fitting availability must be confirmed. Some projects use straight sections plus field-cut fittings for elbows, valves, and flanges.
Provide pipe OD or schedule, insulation thickness, operating temperature, quantity by size, facing or jacket preference, and destination country.
