Excellent Thermal Performance
Reduces heat loss in hot lines and heat gain in chilled lines, helping lower energy costs across your piping systems.
Rockwool Pipe Insulation for Thermal and Fire Safety
What we do
What is Rockwool Pipe Insulation?
Rockwool (mineral wool) pipe insulation from RPS Construction is a reliable thermal and acoustic solution designed for piping systems across industrial, commercial, and refrigeration applications. Manufactured from spun rock (basalt and slag), our Rockwool pipe sections provide excellent thermal resistance, fire safety, and long-term dimensional stability — making them a popular choice where performance and safety matter.
We supply Rockwool pipe insulation across Bangladesh, tailored to local project requirements and climates. If you need custom lengths, diameters, or protective claddings, we can provide specification support and onsite advice.
- Non-combustible / A1 fire classification
- Withstands up to 650°C continuous service
- Excellent acoustic damping
- Moisture resistant with proper cladding
- Dimensionally stable and durable
- Easy to install as pre-formed sections
Why Rockwool wins
Key Features of Rockwool Pipe Insulation
Non-Combustible
Inorganic fibre that does not burn, improving fire safety of piping systems throughout the life of the building.
Good Acoustic Damping
Reduces noise from fluid flow and mechanical systems, making it ideal for occupied buildings and industrial plants.
Moisture Resistant
When paired with vapour barriers or suitable jacketing, resists condensation and moisture ingress on chilled lines.
Dimensionally Stable & Durable
Retains shape under temperature cycles and mechanical stress, ensuring long-term insulation reliability.
Easy to Install
Manufactured in pre-formed pipe sections and flexible mats for fast application on straight runs, bends and fittings.
Where it goes
Typical Applications
Cold Storage and Refrigeration Piping
Insulates low-temperature piping in cold rooms, freezers and food processing facilities.
Chilled Water and HVAC Systems
Prevents condensation and energy loss on chilled water lines in commercial buildings.
Hot Water, Steam and Condensate Lines
High-temperature insulation with appropriate thickness and jacketing for boiler systems.
Industrial Process Piping
For chemical, food and pharmaceutical piping systems requiring reliable thermal performance.
Power Plants and Boiler Systems
Covers high-temperature steam and condensate lines in thermal and combined-cycle power stations.
Marine and Offshore Piping
For vessels and platforms where mineral wool is specified for fire safety and durability.

Protection options
Protective Finishes and Accessories
Aluminium or Stainless-Steel Jacketing
Weather protection and mechanical durability for exposed outdoor installations.
PVC or Polyethylene Jacketing
Economical protection providing weather and splash resistance.
Vapour Barrier Films and Adhesives
Essential for chilled systems to prevent moisture ingress and condensation.
Sealants, Banding and End-Caps
Ensure joints and terminations are watertight and airtight.
We can recommend the correct finishing for outdoor, buried, or indoor exposed installations. Talk to our team for guidance.
Practical guidance
Installation and Handling Notes
- Use pre-formed half-shells for quick assembly on straight runs; use flexible mats or custom cuts for bends and fittings.
- Ensure all joints are tightly butted and sealed with appropriate adhesives or vapour barrier tape for chilled lines.
- Protect the insulation with suitable jacketing in exposed or outdoor locations.
- Store materials off the ground and dry prior to installation.
- Follow project drawings and local codes; RPS Construction can provide installation guidance or work with your contractor.

Frequently Asked Questions
Is Rockwool suitable for chilled water pipes?
Yes. For chilled systems, combine Rockwool with a continuous vapour barrier and weatherproof jacketing to prevent condensation and moisture ingress.
Can Rockwool be used on steam lines?
Yes — choose a high-temperature grade and appropriate thickness. For very high-temperature service, confirm the maximum service temperature with our technical team.
How do I pick the right thickness?
Thickness depends on pipe temperature, ambient conditions, and desired energy loss or condensation control. We can calculate recommended thickness based on your operating temperatures and project location.
Do you supply fittings (elbows, valves) pre-insulated?
We provide custom-cut sections and guidance for insulating fittings. For complex jobs we can coordinate prefabricated insulation covers or site support.
