Rockwool thermal insulation sleeve 800 60/20 1 m — Rockwool stone wool pipe insulation

Rockwool thermal insulation sleeve 800 60/20 (1 m) is a pre-formed tubular stone wool product designed for thermal and acoustic insulation of straight pipe runs and ducts. Manufactured from mineral wool, the sleeve combines high temperature resistance and low thermal conductivity to reduce heat loss and limit noise transmission in heating, plumbing and HVAC systems. The one-metre length and 60/20 profile allow fast on-site assembly and cutting to required runs.

Advantages

The stone wool composition offers stable thermal performance and good dimensional stability at elevated temperatures, while resisting moisture uptake and biological degradation. Pre-formed tubular shape simplifies installation compared with loose or wrapped materials, and the 60/20 profile matches common pipe and duct geometries to provide a consistent insulating layer. The material also contributes to acoustic attenuation of flow and mechanical noise in building services.

Suitable for

• Insulating domestic and commercial heating pipes
• Thermal protection of plumbing and hot water supply lines
• Acoustic and thermal insulation in HVAC ductwork and plant rooms

Key specifications

• Material: stone (mineral) wool
• Format: pre-formed tubular sleeve
• Profile: 60/20
• Length: 1 metre
• Performance: thermal insulation with acoustic damping properties
• Typical application temperature range compatible with heating and HVAC systems

How to use

Measure the pipe or duct run and select the appropriate sleeve length; the product is supplied in one-metre sections that can be cut to size with a sharp knife or insulation cutter. Open the pre-formed sleeve and place it around the pipe so the profile matches the pipe geometry, then close and align adjoining sections to maintain continuous coverage. Joints can be secured with suitable adhesive tape, mechanical fasteners or approved mastics according to installer practice and system requirements. Ensure proper sealing at flanges, valves and bends to minimise thermal bridging and air leakage.

Usage recommendations

Store the sleeves in a dry, ventilated area prior to installation. Use personal protective equipment when cutting or handling mineral wool to avoid skin and respiratory irritation. Follow local building codes and manufacturer guidelines for minimum insulation thickness and fire-safety clearances when applying around heat sources, and consult technical documentation for exact thermal conductivity and permitted service temperatures.
